n the wake of the Battle of the Department of Mysteries Harry was sent home to 4 Privet Drive for the summer holidays. There, he obsessed and brooded over his godfather's death where he hardly left his room and refused meals. As the battle had taken place at one point in the famed Hall of Prophecy, many in the wizarding community including the Daily Prophet began to speculate about the relationship between Harry and that place, leading to, accidentally correct reports calling Harry "the Chosen One", the one destined to defeat Lord Voldemort once and for all.

Dumbledore and Harry searching for Horace Slughorn
Early in his summer, Dumbledore requested that Harry join him in some unknown adventure and arrived to pick Harry up on a Friday, late in the evening. However, they could not depart immediately, because there was a piece of business to attend to: Sirius's will. Much to his chagrin, Harry inherited his godfather Sirius Black's estate, including Grimmauld Place and the Blacks' melancholic and half-crazed house elf, Kreacher. They soon were off, and Dumbledore Apparated Harry to the village of Budleigh Babberton, where Harry was introduced to Horace Slughorn.

In their time together, Harry and Slughorn discussed some of the professor's old students and the improved security at Hogwarts. When Harry and Dumbledore made to leave, Slughorn agreed to return to the school if he got a raise and a larger office. Following their visit, Dumbledore dropped Harry off at The Burrow, where Harry spent the rest of the summer playing two-sided Quidditch, but not before informing Harry that he was to be given special lessons by Dumbledore himself. Later in the summer Harry learned that he had achieved seven O.W.L.s: one 'Outstanding',[86] five 'Exceeds Expectations',[86] and one 'Acceptable'.[86] He also received a surprise when he was made Captain of the Gryffindor Quidditch team, which put him on equal standing with prefects.

Having learned of Professor Slughorn's propensity for hand-picking favourites, Harry experienced this first-hand when he was invited to join Horace Slughorn's Slug Club during the ride to Hogwarts aboard the Hogwarts Express. He did not enjoy the experience, and made to leave as soon as possible. Instead of returning to his seat, Harry made to eavesdrop upon Draco Malfoy, who in a meeting weeks earlier had led Harry to believe he had taken the Dark Mark. What he heard did nothing to dispel his suspicions.

Arriving late to the Welcoming Feast, due to an encounter with Malfoy, Harry learned that Severus Snape had been promoted to Defence Against the Dark Arts professor. While this disappointed Harry greatly, his career as an Auror reopened, as Professor Slughorn would accept his 'Exceeds Expectations' score in Potions. Harry proceeded to take five classes this year: Charms, Defence Against the Dark Arts, Herbology, Potions, and Transfiguration. As Harry had not bothered to buy a text book, Slughorn allowed Harry to borrow an old one from the supply cabinet. When Harry examined it, he found that it once had belonged to a student identified only as the "Half-Blood Prince". The book contained copious handwritten notes that helped Harry excel in Potions for once. In fact, his skills won him a prize from Slughorn — a small vial of Felix Felicis, also known as "liquid luck".

Within the first week of school, Dumbledore made good on his promise of private lessons. He informed Harry that they would be viewing memories of Tom Riddle, before he came to be known as Lord Voldemort. These lessons regarding Riddle's past were in order to learn his secrets and weaknesses. Dumbledore promised Harry that this information would help him survive and would prove crucial to the eventual defeat of Lord Voldemort. In their first lesson the pair delved into the origin of the boy Tom Riddle, by viewing the Gaunt family that once lived around Little Hangleton. During this lesson Harry learned who Tom Riddle's parents were and how they came to be married. He also learned what kind of mindset of the Gaunt family possessed. How Marvolo and Morfin Gaunt believed strongly in blood supremacy, something the Voldemort's mother (Merope) did not share.

Quidditch Captain Harry supervising Gryffindor tryouts
The Saturday following Harry's first lesson, he assumed his Captain's duties holding open try-outs. The first test he administered was a basic flying test, something that proved to be a good ide as it became clear to Harry that most of the students present where not adapt flyers. After an arduous morning of tantrums, foolishness, and many complaints Harry picked the members of his team. The three Chasers, one of which was Ginny Weasley (who out flew all her competition and scored seventeen goals), two Beaters, and Ron Weasley as Keeper. Ron had only survived the tryouts with Hermione's help, whom confunded his competition, Cormac McLaggen.

In studying the Half-Blood Prince's book, Harry discovered numerous spells that the Prince supposedly invented himself, such as Levicorpus and Muffliato. Hermione Granger disapproved of the book, partly because some of its spells have a dark nature, but mainly because it allows Harry to outperform her in Potions. Three times, Slughorn attempts to invite Harry to one of his "Slug Club" parties, but Harry avoids them. Throughout the autumn, Harry used Quidditch to dodge Professor Slughorn's Slug Club events, doing this because he disliked the idea and because it was kinder than leaving Ron alone as Hermione had been invited as well.

Harry pensinive
A private lesson with Dumbledore, Harry about to view a memory in the Pensieve
Harry's lessons were quite sporadic that autumn, and he did not have another one until after tragedy befell someone at Hogwarts. In October, during a Hogsmeade visit, Katie Bell was nearly killed after being bewitched to carry a cursed necklace to Dumbledore. The following Monday, Harry shared his suspicions of Malfoy with Dumbledore during their lesson, only to be rebuffed. In this lesson, Harry first sees Caractacus Burke talking about Slytherin's Locket which a pregnant and desperate Merope had sold him, her husband having abandoned her when she stopped giving him love potion. Dumbledore then focused on Tom Riddle just as he was on the cusp of his Hogwarts years, and Harry discovered a troubled orphan who consciously used his magic to bully and intimidate the other children.

Not long after that meeting, Quidditch season was upon them. In preparation for their first game, Harry replaced the injured Katie Bell with Dean Thomas. The change produced some results, both expected, as the team excelled on the pitch, and unexpected, as Harry found himself in a jealous rage after seeing Dean kissing Ginny after practise. The team's only problem was Ron, who was suffering from a lack of confidence. In an attempt to boost Ron's confidence, Harry blatantly acted as if he had spiked Ron's pumpkin juice with Felix Felicis. Ron took the bait and played a flawless match; however, Hermione took the bait as well and acted unkindly toward Ron and Harry. While she made up with Harry when he told her of the ruse, Ron's sudden relationship with Lavender Brown led to continued strife, as it spiked jealousy in Hermione.

Harry overhears a strange conversation between Draco Malfoy and Severus Snape
While Harry attempted to reconcile his best friends, the Christmas holidays were fast approaching and with them the Slug Club Christmas party out of which Harry could not wrangle. Since "the Chosen One" rumours had been printed, Harry had received an unnatural amount of attention from the young ladies at Hogwarts, specifically a fourth year named Romilda Vane. As Harry could not ask Ginny to the party, he was left to ask Luna Lovegood to attend with him as a friend. This hugely disappointed the gaggles of giggling girls who awaited Harry below every doorway with mistletoe. At the party, Harry was surprised to learn that Hermione attended with Cormac McLaggen, a large Gryffindor seventh year whom Ron despised, and told her that it served her right when he was less than gentlemanly. Later, after Malfoy was apprehended "gate-crashing" the party, Harry learned that Malfoy was indeed up to something and that Professor Snape had made the Unbreakable Vow to protect him.

Harry's Christmas was less than enjoyable, as he was cornered by the new Minister for Magic, Rufus Scrimgeour. Scrimgeour had been hoping to speak with Harry for months and used Percy Weasley as his in. The Minister interrupted the Weasley family Christmas. He tried pitching Harry on becoming the Ministry's mascot, an idea that Harry was not prepared to accept. During the meeting Harry proceeded to tell the Scrimgeour why he would not offer the Ministry his support. The main reasons for his lack of support being: the Ministry's ineffectiveness in dealing with the Death Eater threat, the knowledge that Dolores Umbridge still held a position within the Ministry, the Ministry's refusal to come to his aid when he tried to inform the wizarding community of Voldemort's return the following year, and the mere fact that Harry had no desire to be used. This discussion left Harry and Scrimgeour on increasingly bad terms.

Upon returning to Hogwarts, Harry's sporadic lessons with Dumbledore continued. Early in January, Harry delved into a memory that all but proved that Riddle had murdered his own paternal family after his fifth year at Hogwarts. Then Dumbledore showed Harry a most curious memory, a memory that Professor Slughorn had apparently tampered with, and he gave Harry his first homework assignment: to get the real memory from Slughorn. After impressing Slughorn using a bezoar in class, Harry tried the direct approach only to be instantly shot down.

Slughorns Memory HBP
Harry retrieves the true memory from Slughorn
By 1 March, Harry had still not acquired Slughorn's true memory and had begun to grow more obsessed with Draco Malfoy. That morning he awoke to find Ron under the influence of a very powerful love potion, and he took him to Slughorn, only for Ron to end up poisoned. Harry managed to act quickly and save him with a Bezoar. This was enough for Hermione to overcome her animosity toward Ron, and the three became friends again. Ron survived, but was not fit for the upcoming Quidditch match, so he was replaced by McLaggen. This turned out to be a bad choice, as McLaggen accidentally knocked Harry unconscious mid-match. Upon his recovery, Harry had yet another lesson with the Headmaster.

In his lesson with the Headmaster Harry was upbraided by Dumbledore for not completing his assignment, witnessed the young Tom Riddle murder Hepzibah Smith for the famous artefacts (Slytherin's Locket and Hufflepuff's Cup) she owned, and jinx the Defence Against the Dark Arts post at Hogwarts. However, Harry still could not figure out how to obtain the memory and focused on Malfoy. His interest was bordering on obsession, when Ron came up with the solution to Harry's dilemma with Slughorn: Felix Felicis. In the evening, Harry took the potion and not only managed to obtain the memory, but also solved many of his and his friends's problems, including breaking up not only Ginny Weasley and Dean Thomas, but also Ron and his overly clingy girlfriend Lavender Brown.

Harry&Ginny
Harry and Ginny kiss for the first time, thus beginning their romantic relationship
Even though it was after midnight, Harry immediately went to Dumbledore with the new memory. It confirmed Dumbledore's theory that Lord Voldemort had created not one but multiple Dark magical objects called Horcruxes to ensure his immortality. Together, they theorised that the Dark Lord had created Horcruxes out of special objects such as Riddle's diary and Slytherin's locket. Before Harry left, Dumbledore promised to let Harry join him if he found another Horcrux. With the memory found, Harry had only Quidditch and Malfoy on his mind.

In the week prior to the final Quidditch match, Harry discovered Malfoy crying in the toilet, and a duel ensued. With Malfoy on the verge of using an Unforgivable Curse, Harry cast Sectumsempra, a curse with unknown effects that he found in the Half-Blood Prince's book. The curse nearly killed Malfoy and earning Harry indefinite Saturday detentions. Unable to play, Harry waited with anticipation as he sat through his first detention. When he arrived back at Gryffindor Tower he was happy to discover that they had won the Quidditch Cup. In the heat of the moment he spontaneously kissed Ginny while over fifty people watched, about whom he had been thinking quite often, when she embraced him in the post-match elation; this marked the beginning of their relationship.

Harry inferi
Harry and Dumbledore in the cave overwhelmed by Inferi
On 30 June, Dumbledore led Harry out of the castle in search of a Horcrux. From Hogsmeade, they Apparated to a sea-side cave, where Tom Riddle had traumatised two young children from his orphanage in his youth. The cave was difficult to enter with a toll paid in blood, and to get to the island in the centre of the cave there was only a small boat, only made to fit one. Once on the island, Dumbledore found a basin from which he could not remove the Horcrux without drinking the emerald potion that the Horcrux resided in. Dumbledore extracted a promise from Harry that he would force him to drink, no matter how much he tried to persuade him not to. With this promise, Dumbledore drank and Harry watched as Dumbledore was driven out of his mind, but upheld his promise. When the basin was empty Dumbledore asked for water which Harry was forced to get from the lake, triggering the Inferi that were waiting there. Panicking, Harry was dragged below, but was saved when an incredibly weakened Dumbledore conjured a firestorm that fended off the Inferi. Harry then proceeded to Apparate them back to Hogsmeade Village.

After a short broomstick ride through the village they landed atop the Astronomy Tower. Once on the tower they discovered that Hogwarts had been invaded by Death Eaters, but Harry's friends Ron, Hermione, Luna, Neville, and Ginny, who had been ordered by Harry to watch the school lest Malfoy accomplish his nefarious goal. The D.A. members battled alongside the Order of the Phoenix, on the floor below Harry and Dumbledore, with some help from the remainder of Harry's vial of Felix Felicis. Dumbledore had stopped Harry from fighting and frozen him against a wall with a Freezing Charm, hidden underneath his invisibility cloak, so all he could do was helplessly watch and wait.

The Lightning-Struck Tower, B6C27M1
Harry witnesses Albus Dumbledore's death at the hands of Severus Snape
Harry witnessed the death of Albus Dumbledore at the hands of Severus Snape, and Dumbledore's body then plummeted from the tallest tower at Hogwarts. With Dumbledore dead, Harry was free of the spell that petrified him. He immediately set off after Snape, petrifying a Death Eater and seeking revenge. As the Death Eaters made their way out of Hogwarts Castle and on to the grounds, trying to reach the border where they would be able to Apparate again, Harry pursued and faced off against Snape. Harry tried many times to defeat Snape, even weakly attempting the Cruciatus Curse and Snape's own hand crafted spells, all with no effect. In the process, Snape identified himself as the Half-Blood Prince, and escaped Hogwarts with Draco Malfoy and the other Death Eaters.

Hagrid found Harry and together they managed to extinguish the fire that burnt Hagrid's hut (caused by Thorfinn Rowle) with the Water-Making Charm. Harry then told Hagrid that "Snape killed Dumbledore", but Hagrid refused to believe him. Harry and Hagrid returned to the castle to find people staring at Dumbledore's crippled and lifeless body. Harry moved forward the base of the Astronomy Tower and found his mentor's body lying still upon the ground and Hagrid finally believed him. Harry proceeded to stay next to Dumbledore's body thinking that everything that previously happened that night had been all for not. Harry started crying over Dumbledore’s corpse as well as straightening his half-moon spectacles upon his crooked nose and Harry wiping a trickle of blood from the dead Headmaster’s mouth with his (Harry’s) own sleeve. Hagrid tried many times to get Harry to move, but did not succeed. It was only when he was comforted by Ginny that Harry finally consented to move.

Harry and Dumbledore

Harry took the locket from Dumbledore's robes and was beside himself when he learned it was just a plain bit of jewellery. It was in fact a decoy; there was a note inside the locket that revealed the real Horcrux was taken by someone called 'R.A.B.'. It appeared to Harry that Dumbledore had died in vain and that they had achieved nothing that night. Ginny escorted Harry to the Hospital Wing on McGonagall's orders, where he found a injured Neville apparently asleep in bed, as well as: Ron, Hermione, Luna, Tonks, Lupin, Madam Pomfrey, and Ron's brother Bill Weasley. At some point during the battle Bill had been horribly scarred by Fenrir Greyback. When Ginny announced that Dumbledore was dead, everyone appeared horrified. Harry explained to everyone what had happened on the Astronomy Tower and when he was finished, they were all shocked by what he had said.

The Funeral, B6C30M1

Following the death of Albus Dumbledore, his funeral was carried out. Harry was disgusted to see that Dolores Umbridge and Rita Skeeter had the nerve to attend his funeral, but he did not want to make a scene at Dumbledore's funeral and bit his tongue. Knowing that he would have to hunt down Voldemort's Horcruxes and, fearing for her safety, Harry took Ginny aside, and broke off their romance. Ginny told him that she did not care about the danger of being his girlfriend, but Harry still thought it was best if the two stopped seeing each other. He then spoke to Ron and Hermione, who committed to forgoing their final year at Hogwarts in order to accompany him, despite his protests.

After Albus Dumbledore's death (Dumbledore was the one who began the hunt in July 1996) at the hands of Severus Snape during the Battle of the Astronomy Tower, the mission fell to Harry Potter to complete, if he was to finally defeat Voldemort. He was joined by Hermione Granger and Ron Weasley. With four Horcruxes remaining (plus the unknown soul fragment residing inside Harry) the trio made plans.

Harry, Hermione, and Ron all remained committed to their goal to locate and destroy Voldemort's Horcruxes. To protect their families Hermione altered her parents' memories so that they forgot they had a daughter, then instructed them to move to Australia, and with some help from Fred, George, and their father, Ron transfigured the family ghoul to resemble himself with Spattergroit. Harry's aunt and uncle were taken into hiding by several members of the Order of the Phoenix, such as Dedalus Diggle and Hestia Jones, despite many misgivings on the part of the Dursleys.

The seven Potters
Harry stayed at 4 Privet Drive for a time, but the Order of the Phoenix needed to evacuate him to the Burrow before he turned seventeen. On 27 July the Order sent the Dursleys into hiding first; Harry was surprised by Dudley's gratitude towards him and his goodbye. Six out of thirteen of Harry's escorts took Polyjuice Potion to take on Harry's appearance in order to be diversions if they were attacked, despite Harry's protests. Harry also secretly thought that he wished they would respect his body more. Upon leaving, the group was attacked by over thirty cloaked Death Eaters. Harry rode with Hagrid on his godfather Sirius' old motorbike, that had been modified. They were attacked by multiple Death Eaters, including an Imperiused Stan Shunpike and eventually Lord Voldemort himself, who had invented and mastered unsupported flight.

Harry's owl Hedwig was hit by a stray Killing Curse a Death Eater sent Harry's way. When Voldemort caught up with them, Harry thought this was the end, but his wand acted on its own to strike out at the man who was both "kin and mortal enemy", destroying Voldemort's borrowed wand. The chaos ended when Harry and Hagrid passed the protective enchantments placed over the house of Nymphadora Tonks' parents, although Harry was still completely grief-stricken over the death of his beloved owl. After finding Hagrid safe and sound, the pair took a Portkey to the Burrow, where he found a worried Molly and Ginny Weasley standing watch outside in the darkness.

After the battle of 7 potters

Harry was relieved to see that Hermione and Ron were fine, but was shocked when Remus Lupin arrived with George Weasley, who had lost an ear. Everyone else arrived safely, but Alastor Moody who had been murdered by Voldemort and Mundungus Fletcher, who had Disapparated as soon as the fight started. Many amongst those gathered at the Burrow believed that they had been betrayed, but Harry refused to believe any of those he loved would sell him to Voldemort, much to the chagrin of Remus Lupin. Harry then stormed outside, where he was struck by a vision of Voldemort torturing Ollivander.

Rufus Scrimgeour: "Remembered you're not at school, have you? Remembered that I am not Dumbledore, who forgave your insolence and insubordination? You may wear that scar like a crown, Potter, but it is not up to a seventeen-year-old boy to tell me how to do my job! It's time you learned some respect!"
Harry: "It's time you earned it."
— A row during the reading of Albus Dumbledore's will[src]
Once settled in at the Burrow, Harry, Ron, and Hermione helped prepare the wedding ceremony of Bill Weasley and Fleur Delacour. The day before the wedding, the group celebrated Harry's seventeenth birthday. Harry received a watch from Mr and Mrs Weasley, a traditional coming-of-age gift. Ginny also gave him the most passionate kiss they have ever shared. It was something to remember her by in case he "meets some veela" during the Horcrux hunt. Harry responded by saying that "dating opportunities will be thin". The pair was then interrupted by Ron and Hermione.

Scrimgeour gives the first Snitch Harry caught, willed to him by Albus Dumbledore
At the party that night, Minister for Magic Rufus Scrimgeour arrived to release the contents of Albus Dumbledore's will. Harry was left the first Snitch he had ever caught in a Quidditch match and Godric Gryffindor's Sword; Scrimgeour withheld this second gift, claiming that it was a historical magical item and was not exclusively Harry's property. Noting that Harry, Ron, and Hermione were the only students mentioned by name in the will, he asked the trio why this was; the three were unable to give him an answer.

On 1 August, Harry attended Bill and Fleur's wedding disguised as a distant Weasley cousin, Barny Weasley. They used polyjuice potion and the hairs of a red-haired Muggle boy from the village to disguise him. During the party, Harry met Luna Lovegood's father, Xenophilius, (who wore a necklace bearing an Triangle-Eyed symbol) and Viktor Krum, (who dislikes the symbol for it is synonymous with the dark wizard Grindelwald, who attended Krum's school, Durmstrang). The reception was interrupted when the Patronus of Kingsley Shacklebolt arrived and announced the fall of the Ministry of Magic and the death of Rufus Scrimgeour. Chaos erupted and guests started to flee, while Harry and Hermione drew their wands and grabbed Ron before Disapparating to Tottenham Court Road.

There, Hermione revealed that she had planned ahead, packing supplies in her bag, which had an Undetectable Extension Charm on it. Ron changed, and Harry put on his Invisibility cloak, and the three then entered a nearby café to hang low for a while. Whilst at the café, Ron and Hermione discussed the events of the wedding and Voldemort's coup. They unwittingly broke the Taboo curse that had been placed on Voldemort's name when the Death Eaters overthrew the Ministry of Magic, alerting Death Eaters Antonin Dolohov and Thorfinn Rowle to their location. After a brief skirmish, the trio defeated the Death Eaters, whose memories Hermione wiped at Harry's suggestion. Harry, Ron, and Hermione then found refuge at 12 Grimmauld Place.

Harry labelled as "Undesirable No. 1" by the Ministry
Having found no leads regarding the Horcruxes over the summer, Harry discovered R.A.B. during the trio's first morning at 12 Grimmauld Place. Once Hermione remembered that the locket had been in the house during its occupation by the Order of the Phoenix, Harry summoned Kreacher, and they learned that it had been stolen by Mundungus Fletcher. When the trio questioned him about it, he revealed that it was now in the possession of Dolores Umbridge. On the same day, Remus Lupin had been to visit. He asked Harry if he could join them, but once Harry found out that Tonks was pregnant, he refused. This caused a temporary rift between the two of them.

For the following month, the trio would take turns under the Invisibility cloak to watch the Ministry entrance. On 2 September after formulating their plans, they managed to infiltrate the Ministry. Using Polyjuice Potion Harry transformed into Albert Runcorn. He searched Umbridge's office but did not find the locket. He did, however, take Moody's eye from her door. Finding Umbridge trying Muggle-borns for "stealing" magic, Hermione managed to trick Umbridge into revealing the locket, and she lied about how she obtained it.

Furious, Harry stunned both her and Yaxley. He and Hermione freed the Muggle-borns who were being held by the Muggle-Born Registration Commission, and Hermione conjured a copy of the locket while they took the real thing. They met up with Ron again and escaped, though Yaxley grabbed Hermione’s arm while they were Disapparating. She evaded him with a Revulsion Jinx, but the location of 12 Grimmauld Place was revealed to him, and they were forced to abandon it as a hide-out. But instead Hermione took them to the woods that were once the location of the Quidditch World Cup.

Ron Weasley : "Yeah, I thought I did too."
Harry: "So what part of it isn't living up to your expectations? Did you think we’d be staying in five-star hotels? Finding a Horcrux every other day? Did you think you’d be back to Mummy by Christmas?"
Ron Weasley : "We thought you knew what you were doing! We thought Dumbledore had told you what to do, we thought you had a real plan!"
— Harry and Ron have a nasty row before the latter's departure[src]
After securing Slytherin's locket, the three friends took turns wearing it, to ensure it was not lost. The locket had a negative influence on all of them, straining relations and causing them to all act moody and inclined to get into petty arguments. They overheard a goblin saying that the sword protected by Snape was a fake. They learned that the Sword of Gryffindor in Snape's office was a copy of the real sword, and that they would have to trace the location of the real sword.

Harry ron fight
Harry and Ron Weasley row before Ron abandons the hunt
Harry and Hermione were excited at knowing what object they could use to destroy Horcruxes, but the locket's negative energy pushed Ron over the edge. Knowing that they now had something they were not close to destroying, Ron and Harry got into a horrible row. Ron accused Harry of not knowing what he was doing and not being very concerned when they learned that Ginny Weasley had been punished for attempting to steal Gryffindor’s sword for them, along with Neville Longbottom and Luna Lovegood. Ron then abandoned his friends accusing Hermione of preferring Harry to himself.

Ron’s departure left both Harry and Hermione depressed. After some listless time in which they accomplished nothing, they decided to head to Godric's Hollow, as Harry wanted to visit his parents graves, and Hermione had convinced herself that Dumbledore might have entrusted the Sword of Gryffindor to Bathilda Bagshot, a magical historian who lived there and who had been friendly with the Potters and the Dumbledores.

They arrived on Christmas Eve. After seeing the memorial dedicated to his parents and himself, Harry and Hermione searched the graveyard for the Potters's grave and came across the grave of Kendra and Ariana Dumbledore and that of Ignotus Peverell. Harry was filled with regret that Dumbledore had not shared this connection with him. Upon discovering Harry's parents's grave Hermione called out to him and comforted Harry when he reached the grave. After placing a conjured wreath of flowers on his parents’s graves, the two then met Bathilda Bagshot, who motioned for them to follow her into her home. Believing Bathilda wanted to give him Gryffindor's Sword, Harry accompanied her upstairs alone when she indicated that Hermione should stay downstairs.

Once there, she questioned Harry in what he did not realise was Parseltongue, revealing herself to in fact be Nagini, Voldemort's snake. Voldemort had murdered Bathilda and animated her corpse to hide Nagini, who attacked Harry, biting and coiling herself around Harry. Hermione raced upstairs and repelled the snake, while Harry's scar burned, alerting him to Voldemort’s approach. The pair managed to escape, but Harry was knocked unconscious and such a close call with Voldemort caused the connection to re-open and Harry had a vision of his parents' demise. And in the scuffle, Harry's wand was accidentally broken by Hermione's Blasting Curse.

After escaping Voldemort, Harry and Hermione camped out in the Forest of Dean, where Hermione healed Nagini’s bite with Dittany. When they were camped out there, Harry and Hermione read parts of Rita Skeeter's biography of Dumbledore, The Life and Lies of Albus Dumbledore which Hermione had stolen from the home of Bathilda Bagshot. Upon reading, Harry felt betrayed, because Dumbledore had not shared this information with him. Hermione tried to convince Harry that Dumbledore had his best interests at heart, but Harry became quite disillusioned.

A couple nights later, while standing guard outside the tent, Harry was lead by a silver doe Patronus to a frozen pool into which someone had placed the Sword of Gryffindor, which leads Harry to strip to his underwear and jump in the pool. While trying to acquire the sword, the locket attempted to strangle him, but he was rescued by Ron, who had returned through the use of his Deluminator.

As Ron had saved his life, Harry forgave him for leaving, and after seeing the Horcrux torture Ron, explained that he had no feelings for Hermione beyond that of a sibling. Hermione, who had been inside the tent during the destruction of the Horcrux, was angry with Ron for a longer period.

Xenophilius-Lovegood
The trio speaking with Xenophilius Lovegood at his home, near the village of Ottery St Catchpole
On 30 December at Hermione's request, the three friends travelled to Luna Lovegood’s home to question Xenophilius Lovegood. They asked about a triangular symbol Dumbledore had left them to decipher in the book he bequeathed to Hermione. After learning of the Deathly Hallows, Harry, Ron, and Hermione discovered that Xenophilius summoned Death Eaters in an attempt to persuade them to return his abducted daughter. The trio escaped the Death Eaters when Hermione blasted the floor open to show them Harry, but managed to keep Ron's alibi of being sick at home with spattergroit intact by covering him with the Invisibility Cloak.

Harry soon became obsessed by the Deathly Hallows. He spent everyday brooding over the possibilities forgetting about his responsibilities. With Harry's new found obsession with the Hallows he became more and more withdrawn and listless. He came to believe that the Resurrection Stone was enclosed within the Golden Snitch bequeathed to him by Dumbledore. He also surmised that Lord Voldemort was abroad in a search for the Elder Wand. This obsession troubled his friends, and with the drop in Harry's attentiveness, Ron's leadership qualities flourished.

"You're a lying, you filthy Mudblood, and I know it! You have been inside my vault at Gringotts! Tell the truth, tell the truth! What else did you take? What else have you got? Tell me the truth or, I swear, I shall run you through with this knife! What else did you take, what else? ANSWER ME! CRUCIO!"
—Overheard parts of Bellatrix's interrogation of Hermione Granger[src]
After listening to a broadcast of Potterwatch around Easter 1998, Harry determined that Voldemort was seeking the Elder Wand, and accidentally broke the Taboo on Voldemort's name. Captured by a gang of Snatchers led by Fenrir Greyback, the trio were questioned about who they were. Hermione had previously hit Harry in the face with a Stinging Hex, attempting to conceal their true identities, but it all amounted to nothing as the Snatchers then found the Sword of Gryffindor. After Greyback and Scabior realised that they had caught Harry Potter, the trio were taken to Malfoy Manor in Wiltshire. The Snatchers decided to forgo taking Harry to the Ministry, but instead to Voldemort directly.

When Bellatrix Lestrange learned that Harry had been caught, she sought to summon Voldemort, until she noticed one of the Snatchers had the Sword of Gryffindor, which was supposed to be in her vault at Gringotts Wizarding Bank. From her drastic change in tone of voice and her worries that they would all perish, Harry determined that another Horcrux was hidden there, as well. Bellatrix isolated Hermione for interrogation based on the knowledge that she was Muggle-born, stating that she wished to talk "girl to girl with her" and proceeded to brutally torture her with the Cruciatus Curse. While being tortured Hermione lied, claiming that the Sword was just a copy. Harry convinced Griphook (a goblin prisoner) to support this story, knowing that Bellatrix would interrogate Griphook next, as she would want a goblin's opinion on the Sword.

In panic as Hermione screamed in pain upstairs, and Ron sobbed at hearing her, Harry called out for help — a cry heard by Aberforth Dumbledore through a fragment of a two-way mirror in the cellar. Aberforth sent Dobby the house-elf to rescue the prisoners. Harry had him take Luna Lovegood, Garrick Ollivander, and Dean Thomas to Shell Cottage, while he and Ron went to rescue Hermione. On the way, they had to fight Peter Pettigrew, whose silver hand strangled him to death when he hesitated to hurt Harry, who reminded him that he had once saved his life. A skirmish ensued upstairs, during which Harry took Draco Malfoy's wand from him, and he and Ron saved Hermione and Griphook with Dobby's assistance.

As they escaped Malfoy Manor by Apparition, Bellatrix Lestrange threw a silver dagger to where they were Disapparating. Harry was initially relieved to realise he had managed to apparate to Shell Cottage with Ron, Hermione, and Dobby in tow, but was horrified to see the knife protruding from the elf's chest. Harry managed to lie him on the grass, where Dobby collapsed and died in Harry's arms his last words being Harry's name.

Harry decided that he would not dig Dobby's grave with magic, opting instead to do so manually, using a shovel; this was his way of both repaying Dobby's bravery and ebbing his own grief. As he dug, he got glimpses of Lord Voldemort furiously punishing Bellatrix Lestrange, the Malfoys, and the others that were present in the manor for their failure to keep him in their custody and allowing him and the other prisoners to escape.

Harry, his scar now burning temptingly threatening to have Voldemort's thoughts engulf him, was finally able to learn control of denying Voldemort's entry into his mind. He attributed this to his grief and love for Dobby. While digging the grave, more understanding came to Harry. He realised that though the Deathly Hallows were tempting objects, Dumbledore had tasked him with destroying Horcruxes. He decided to trust Dumbledore, reaffirming his faith in his mentor. During the funeral, Luna Lovegood gave a short eulogy to Dobby, and Harry managed to say his final goodbye to one of his most loyal friends.

Harry: "Nor do I, much."
— The solution to Griphook's demand for the Sword of Gryffindor[src]
Following the death of Dobby, Harry, Ron, and Hermione stayed at Shell Cottage for some time. During their stay, the trio formed a plan to break into the Lestrange Vault to obtain the Horcrux within, with the help of Griphook. Due to the fact that Griphook would only help in exchange for Godric Gryffindor's Sword, Harry decided to word his request so that the handover would not take place until after Harry had used it to dispose of the remaining Horcruxes. Harry also found out information regarding the Elder Wand from Ollivander. He learned that his hunch that Elder Wand was real and that Voldemort was going abroad to search for it was correct. Harry also learned some complex wandlore, such as what happens when a wand's allegiance changes to that of another individual and that a wand's allegiance doesn't necessarily have to change hands through murder, as most (including Lord Voldemort) believed.

Although feeling guilty for the deception, Harry knew that the sword was their only known weapon against the Horcruxes. The other residents of Shell Cottage could not fail to notice the trio's behaviour. Bill Weasley took Harry aside and advised Harry to be cautious when making deals with Griphook who Harry was increasingly disliking. Around the same time, Remus Lupin came to Shell Cottage bearing tidings of new birth. He asked Harry to be the godfather of his newborn child, Edward Lupin. It seemed as if the incident between them at 12 Grimmauld Place had never occurred.

The trio and Griphook left Shell Cottage early on the morning of 1 May to break into Gringotts. Hermione disguised herself as notorious Death Eater Bellatrix Lestrange, using Polyjuice Potion. The goal was to try and fool the goblins at Gringotts into believing that it was really Bellatrix who was entering the vault. The trio had Bellatrix's wand that Harry had captured at Malfoy Manor as further proof for the disguise. Ron was Transfigured to look like a foreign wizard named Dragomir Despard, and Harry had Griphook on his shoulders; both were under the Invisibility Cloak.

Their plan proceeded reasonably well; Hermione made a convincing Bellatrix, despite a close encounter with a Death Eater named Travers, whose suspicions seemed to be eased and accompanied the group to Gringotts. Two human guards there had Probity Probes that detected concealment charms, and Harry used a Confundus Charm on them to get Hermione passed unchecked. Inside, the Goblins requested Bellatrix's identification. When Hermione hesitated, one nervously said that her wand was sufficient proof, though Hermione claimed it was new. Harry suspected the goblins knew that Bellatrix's wand was stolen and were looking for an impostor.

Griphook told Harry to use the Imperius Curse, he complied and Bogrod then accepted the wand as being correct. Bogrod requested the Clankers, and then led the trio, Griphook, and Travers into a passageway. The door slammed shut, and Harry sent Travers away to hide. Bogrod, still under the Imperius curse, summoned a cart that descended deep within Gringotts. After many twists and turns, the cart passed through Thief's Downfall, a security waterfall that washed away all illusion charms. When the cart overturned and dumped them out, Hermione and Ron had been reverted to themselves. Griphook believed the other Goblins knew they were impostors, but Harry wanted to continue and cursed Bogrod again.

The trio and Griphook found the vault guarded by an aged, half-blind dragon. Griphook subdued it using the Clankers. Hearing pursuit approaching, Harry forced Bogrod to open the vault, which was filled with precious objects. Hermione screamed in pain, and they discovered that the vault's protective charms included the Flagrante and Gemino curses: the contents would multiply and become searing hot every time something was touched. Harry spotted Hufflepuff's Cup, the Horcrux, but it was out of reach. Hermione levitated Harry by the ankle and he snagged the Cup by using Gryffindor's Sword. Meanwhile Hermione, Ron, Griphook, and Bogrod all struggled to stay above the searing-hot rapidly multiplying objects below.

As Harry was setting himself down, he dropped both the Sword and the Cup. Griphook grabbed Gryffindor's Sword, and flipped Hufflepuff's cup up into the air. Harry caught it, ignoring the searing heat. Borne by a treasure avalanche spilling from the now-opened vault, Griphook ran off with Gryffindor's Sword, yelling that thieves were in the vault. Harry, Hermione, and Ron hurled curses at the Goblin throng. Harry released the half-blind dragon and the three jumped on its back. The freed dragon took flight, the three blasting holes into the ceiling for it to fly through as they made their escape.
