Since time immemorial, the land of El Sallia has been influenced by the power of the gods.
Among them, the evil god Chaos was worshipped by the Devil tribe, while the goddess of light, Lushiris, had the devotion of the humans.
Both gods had an avatar to act as their representative on earth, Böser, a prince of darkness bound to the soul of a human, and Jessica, a powerful mage.
