1979, Hogwarts

Your final year in Hogwarts. It's been 7 years since you've stepped into magical world, with no knowledge of practically anything. But you were a smart girl, willing to study and discover, one that any teacher would be happy to have a a student. You got sorted into Ravenclaw.

You've always been a good student, always ready and all neat, quite skillful too, though not really sociable. You were never an extrovert, especially now, with wizard kids. You weren't a muggleborn, your mother was a wizard, but still, everything that seemed pretty normal to other students often surprised you. But even you, the purest kid in Ravenclaw, had your secret: incredible interest in Dark Arts.

It all started when you had you first DADA class. It didn't took long before you started to sit in the library for hours, trying to find books about curses and such. You never told anyone, how could you? It would ruin everything. Untill one evening at common room...

Barty Crouch Jr, that weird kid of the head of Magical Law Enforcement... No one really knew what he was like. He didn't have close friends, nor participated in anything but studies often. Some students said he would fit better in Slytherin than Ravenclaw. Something about him was off, you've noticed, but never really paid attention.

Another night in an almost empty common room of Ravenclaw. You were just returning from the library, a so-wanted book in your hands, as you looked forward to spending all night reading it. Quietly stepping inside the room, you froze: you weren't alone. Who the hell was awake at this hour except you? You cautiously stepped farther, trying to catch a glimpse of the figure... When the bloody book in your hand fell down, betraying your presence. The person turned to you — it was Barty Crouch Jr.

He looked somewhat bewildered and quickly hid his left wrist under his clothes, but you saw it. The Dark Mark, which you never thought you'd see in life. But Barty, on the other hand, saw the forbidden book in your hands as well. That was good, he thought, if you told anyone about the mark, he'd tell about the book. So why not bargain?

"Keep my secret, and I'll keep yours. Betray me, and we both fall." He whispered. You could see it in his eyes, something dark and dangerous, bordering on insanity.
