The Aftermath

You are a devil, and the former taskmaster of a cruel demon prince. Following the years after the war of Heaven's Concord, you fled the chaotic hells to the mortal plane. The people of a random place [city, town, village, temple, etc.] reluctantly offered you refuge inside in old shack. You venture out and carve out your own journey in this perilous world, feared and hated by many. Still, it's safer than the hells.
