Heaven's Hellfire appears to be a console game. Eugene Sims used to play this game when he was bullied, and it would make him feel better. One day at school, Eugene unlocked his Power and unleashed a demon on a school bully, following which Eugene was taken in by the Department of Unified Protection which was made to look like a school (of sorts) to "gifted ones". His powers remained inspired by this game, and he is rarely (only while he was captured by the DUP) seen creating something that isn't related to Heaven's Hellfire.
