Agartha of the Netherworld
In a world ruled by a reptilian race known as Draconians, humans serve as a subclass labor force. A miner named Alec has always held disdain towards draconians and seeks to free his people. While working in the mines he comes across an ancient demonic being that offers to give him the power to free his people in exchange for the slain souls of draconians so he can retrieve his body. Alec makes a deal with the demon and with his first action turns against the general Dracovus that rules over his camp. The demon helps Alec make an example of him and curses him, turning him into a human so he can live a life separated from all he has ever known. Dracovus refuses to accept his fate and as his army turns against him, he defeats them and wears their bones as his armor. What follows is a war lead by Alec and his demon. Dracovus learns what it means to be human and fights against Alec.
