Thanatos is... The God of Death and brother of HYPNOS. God of Death? It's all so morbid. Why can't we have a God of Death by Chocolate?But we can soften the blow and call him the God of Everlasting Sleep. People think that Hades is the god of death but Hades is really the god of he underworld, and partly the god of wealth because a lot of rich material (gold,obsidian,etc.), check Hades for more information.
