Demons of Lust, are twisted and inhumanly beautiful seducing and corrupting those around them.
Demon of War, powerful and terrible harbingers of war and destruction. Covered in spikes and barbs wielding gore-dripping weapons. Massive horns sprout from their heads and barbed tails slash.
Demon's of Corruption, twisted and deformed spreading plague and disease. Swarms of rats are normally the first sign of a demon of corruption. The rat-headed monstrosity is covered in boils and scabs, weeping puss and blood from ulcerous wounds. Swarms of flies buzz around them.
