Thorfinn Rowle

Thorfinn Rowle was a wizard and a Death Eater who fought in the Second Wizarding War. He fought at the Battle of the Astronomy Tower, where he accidentally killed fellow Death Eater Gibbon, burned Rubeus Hagrid's cabin, and tortured Harry Potter. In 1997, he tracked Harry Potter, Ron Weasley, and Hermione Granger to Tottenham Court Road along with Antonin Dolohov, but the two Death Eaters were defeated and their memories were modified by Hermione to cover their escape. After this failure, Rowle was punished by Voldemort. He also fought at the Battle of Hogwarts. His fate after the battle and Voldemort's final defeat, however, is uncertain. Though, he is most likely to have been sent to Azkaban for his crimes.
