Demogorgon

Demon lord. Originally one of the Old Gods, Demogorgon supported Ema at the Godmoot when the gods split into two factions - those led by Ema who wanted the lesser races to be given the Gift of Death (the 'Demons' and those led by Eyal who wanted them to be given immortality. When the two factions went to war, the Demons chose Demogorgon to command their army.
