For 500 years, Oz the Dark Lord was paralyzed inside a magic barrier. Long ago Oz led the war against humans, until the humans won. Since then, his demons had learned to coexist with humanity. There were halflings. Yes, the species were interbreeding. It was deplorable. Demons should be driven to kill all humans. Violence and mayhem. This coexistence was an offense to the Dark Lord. Oz has risen again, and while evading hunters he is gaining strength. Every victory brings him closer to his former glory.
