Oni

Descendants of bloodlines that were banished to the Outerlands of Diyu for crimes against Sheng, the Oni are a  hardy race of people that can withstand the intense heat of the volcanic ashlands. They're a rare sight, given how hostile the predators in the region are, but Xuantong's border villages are occasionally raided by Oni tribes.

Not much is known about them beyond the tales told around campfires. Given their disgraced heritage and mutated appearance, they're considered less than human by the citizens of Sheng.

In 1285AC, a tribe of Oni acted as mercenaries to the infamous dread-sorcerer Baomun the Silver. The aged magi was discontent with his life as a noble, and appealed to creatures of the night to rally an army. He succesfully captured the Izhurian palace for four nights, before sailing eastward to unknown lands with numerous treasures upon his ship.

The Oni were described as brutish, foul-mouthed, but with enough physical strength to match a kaor-class demon.
