Katrina Ravencroft

Backstory

Adopted by muggle parents, Katrina had no idea that she belonged to a world full of magic. Until one day, a strange woman by the name of Fiona showed up at her door, claiming she was her biological mother. Katrina, of course, did not believe her and with the help of her father, sent her off. 

Then came her 11th birthday. Katrina's father was infuriated, mumbling something about him thinking that living in the muggle world would keep them away from magic. Katrina fled. She was picked up by a purple bus called the "Knight Bus", where she found Fiona waiting for her with a concerned look. Her mother explained everyhting, how she had been in captivity by the Dark Lord, and how Katrina's father had taken her at a young age due to hate for the wizarding world after the First Wizarding World. 

Katrina agreed to attend the magic school, Hogwarts. There, she was sorted into Slytherin, and met a boy named Arion Whitlock. The two fought in the Second Wizarding World against the Death Eaters. They came back for an eighth year at Hogwarts to replace their seventh, and graduated. 

Katrina studied to become an auror, Arion a healer. He proposed on her 23rd birthday, and they got married a year later.
