I was in the line of first years ready to be sorted into a Hogwarts house. 
"Lili...SLYTHERIN" I saw some professors look at each other sadly what did that mean? I walked over to the Slytherin table i had heard lots of adults talking about the strange kids at Hogwarts in accidents and dying or staying at Hogwarts for the summer but I realised something all of them were Slytherins why? What was his Mystery? I decided I would find out. I ate my food and settled into my dormitory but professor Penrose came in and called 3 of us Slytherin 1st years to his office in the dungeons "yes professor" we said there was me and two other boys. "What do you want us for professor?" I asked "aaah you will be my special students who get extra house points!" He answered but I could tell he was lying by the look of his eyes. But the other two boys sounded excited "really us but why us?" Professor penrose didn't answer. We soon came to his office "inside kids" I could tell I was about to find out something big.   
"Now before I do what I'm going to do I will explain everything to you three"     
"Explain what?" I asked     
"Well after you know who died the ministry for magic decided we didn't want to risk any more Villians so they cam up with a way to stop Villians from rising and that way is killing all of the Slytherins so I bet you know what I am going to do now... Avada kadavra" he said calmly and the boy to my left fell forward Dead "avada Kadavra" he said calmly again and the boy to my right slumped forward Dead I realized I can't let him kill me im the one with the answer I'll escape!  Apparently escaping wasn't as easy as I had thought I ran to the door but it was locked "Alohamora" I said pointing my wand at the lock nothing why won't it work? Please work work work work. "alohamora, alohamora, alohamora, alohamora click it unlocked I ran through the door down the hallway into an empty class room. "What in the worl is going on?" I asked my self "killing all the Slytherins that's not going to solve anything!" Then I realized I wasn't alone there was a girl she was prabably maybe a 2nd year. "Hello what's your name?" She just starred at me then finally she said "don't trust the professors there going to kill all the Slytherins I'm stuck in the castle last year I escaped from them trying to kill me but I haven't been able to leave this hidden room"    
"What do you mean by hidden room?" I asked    
"The room of requirements" she said simply     
"Ooh, what's your name?"   
"Piper"   
"Nice to meet you Piper I'm Lili"   
"Hi Lili you will have to stay with me now it's the only safe place left".   
"What about classes?"    
"Do you have your books?" She asked    
"Yah I do" I said    
"Practice in here I can't because I've already memorized all the books".      
"I can write to my parents to get me more books if you want to they don't ask questions"   
her eyes lit up "yah that would be great!"     
so I called my owl over and wrote the letter. 
I didn't know at the time but I had just found myself a true friend.
