Chaos, supreme god, creator of the Universe and all its inhabits, decided at one point in his creation to make the world of Aeterna. He populated it with different races and appointed wise rulers to show the way. Before long, these beings turned against their creator, grouping into two large groups and giving rise to war, death, and hatred. This angered Chaos who, in his infinite immortality, took it as an insult to his magnificence and cast a terrible curse on the kings of both factions. He named them King of Darkness and Queen of Light and condemned them to fight each other until the end of days. Cursed, even death could not free them from their destiny since, even if they defeated their opponent, Chaos granted them the Gift of Immortality and they were reborn again to regain their power and continue their eternal war.
