In 1720, Damien LaCroix was a young man of good standing. He was in love with a servant in his household. Preparing to elope with her, he startled his brother. In the dark, they shot each other. His brother survived, but Damien died instantly. Hours later, he woke up, an immortal. For years he remained at home, guarding his family, until his family was killed by a vampire. From then on, Damien devoted his life to the destruction of all vampires. He discarded his name, adopting Thorne instead. At the site of each of his victems death, he leaves a blood red rose, in remembrance of his family.

Thorne appears to be in his mid twenties. He stands 6'1", has blonde hair, blue eyes, and well defined cheekbones.
