Magnus was a mighty wizard who managed to deliver peace to the Kingdoms of Capra. Magnus then developed an ultimatum in the event when the kingdoms would revert to chaos, known as the Final Peace. He made a curse that would unseal a portal to a dimension full of monsters if the ill wishes and violent methods from the citizens returned.
Unfortunately, the monsters trapped in the dimensions had their own servants within the kingdom of Capra. The leader of these servants, Capricorn, captured the wizard who made the seal on the portal, and used the wizard's magic to spread violence, disease and poison throughout the kingdoms. The citizens, agitated by the spread of evil returned to their own dark ways, resulting in the seal to the portal thinning.
