Hesper Starkey, the current Head Girl of Slytherin

Two of you found Hesper Starkey, the current Head Girl of Slytherin, outside the dungeon. You're quite acquainted with her, as you two were in the top 3 students of Potions class.

"Hi, I heard that you're studying how the moon's phases affected potion fabrication. I think it sounds promising."

"Thank you. What brought you here?"

"I think this girl needs your help."

Under your convincing, Clarisse began to tell her story.

She was engaged to Corvus Lestrange. His mother Eglantine was the older sister of her mother Leonie. And now her fiancé wanted her to quit school to become a bride since she just had her 18th birthday yesterday.

You asked: "Why did he do that?"

"I think that's related to the **** of his wife."

"Hold on, I think you're his fiancée?"

"Corvus was acquainted with Mustafa Kama, head of the Kama Family. He was charmed by the beauty of his wife Laurena. One night, Corvus Lestrange put Laurena Kama under the Imperius Curse, then kidnapped and **** her..."

"That's horrible."

"Corvus never loved her. He just wanted an heir, and Laurena has had a son with Mustafa. However, after forcibly had a daughter with him, she died shortly after giving birth..." Clarisse couldn't continue, but everyone knew what was waiting for her.

Hesper frowned: "The Lestrange family is very powerful. I knew that at least two of the Hogwarts Board of Governors are from this family. They have influence in the Ministry of Magic too, otherwise, Corvus can't get away after using an Unforgivable Curse. This is beyond our abilities."

"Can we talk with the Headmaster?"

"We should not. The Black family and the Lestrange family are closely related. I think we should ask the Head of our House for help."
