Killed by the bloody baron. Helena Ravenclaw is naturally the resident ghost of Ravenclaw College. She is the daughter of Rowena Ravenclaw, one of the founders of Hogwarts. In that year, in order to gain more wisdom, she stole her mother's crown (Ravenclaw's crown, which Voldemort later made into a horcrux) and was chased by the Blood Baron.

The bloody baron caught her in Albania, but she refused to go back to Hogwarts with Barrow, who killed her in a rage. The crown is hidden in a black forest somewhere in Albania.

One of the four founders of Hogwarts School of Witchcraft and Wizardry in rowena ravenclaw's literary work Harry Potter, and the founder of Ravenclaw College.

She believes that "the students we teach must be superior in wisdom."

Rowena ravenclaw likes intelligent, fair, intelligent, knowledgeable, intelligent, far-sighted and curious students, and likes to study things. Ravenclaw is beautiful and a bit harsh, and comes from a quiet river. She thinks that the cleverest mind is the most promising.

Famous saying: Extraordinary intelligence is the greatest wealth of mankind.
