Tulip Karasu

Tulip Karasu (born c. 1973) was a witch who began attending Hogwarts School of Witchcraft and Wizardry in 1984 and was sorted into Ravenclaw.

Early life
When she was young, she lived a very strict life due to her parent's employment in the Department of Magical Law Enforcement in the British Ministry of Magic. This resulted in her growing a rebel spirit, which she hid from her parents or anyone else.

Early years
When she first attended Hogwarts School of Witchcraft and Wizardry, she met Merula Snyde and was attracted her lifestyle (with her parents in Azkaban, Merula was free to do what she wanted), so she became friends with her. As the Cursed Vaults became important in their first school year, they made their destiny to open the Vaults and show the world that they were as good as everyone else. They soon stumbled upon Jacob's old research room, but then started to gather information behind the others back, thus causing a falling out. They locked the room with two keys, one for each of them, so that neither could do any research nor could anyone else get in.

Third year
In the 1986–1987 school year, she met Jacob's sibling, who was in the same year as her. She helped them to get the Key from Merula Snyde, and taught them the Boggart-Banishing Spell.

Etymology
Tulip, the flower of the same name, originated from Persia and Turkey; Tulip, as a name, is also of Turkish origin as a result of it. In Turkish, tülbent means turban – the shape some thought the flowers resembled.

Karasu, as a surname, is relatively most common in Turkey. It means "black water" derived from Turkish kara meaning "black, dark" combined with su "water". Karasu is also the romanization of crow in Japanese, though not known to be a surname on its own.

Behind the scenes

 * Given the origins of her first and last names, she's likely of Turkish descent.
 * As her last name could also mean raven, it may be a hint or a play on the character's sorting into Ravenclaw.
