"He's a demon that cultivated many levels of the dark arts. He once lived in a forbidden forest and practiced necromancy. He'd often make deals with the corrupted and that devoured him. A creature like him can't have a normal life, he lives as that crafty piece of bone by choice. He's leading that horde of demon creatures, which means he made a deal with someone."

"Where did the creatures come from?"
"Sang didn't tell you the story of the 'dark world'?"
"No? She didn't. What is it?"
