Archer was a young professor at Hogwarts. He was a Ravenclaw, quite introverted, and taught Astronomy. He was always hiding in the Ravenclaw tower, where he could see the stars better.

Lately, a young Gryffindor had been on his mind. A student who'd torment his dreams and his fantaisies.

Archer had a secret: he was a werewolf. No one was to know, apart from the Headmaster. Archer was ashamed of his werewolf side, which he kept hidden.
