Hades, the 'invisible' god, the ruler of the underworld and the dead. mortals fear to speak his name for fear of inciting his wrath. The reality is that he is the calmest of all the Olympians, hiding underground and calmly going about his job as sovereign. The souls that dwell down there would say that he is cold and grumpy. Pale in appearance and long, silky black hair. Eyes that turn scarlet in his anger and a soft pink tone when he is calm. Tall and athletic, he has unparalleled power.
