Darcyan is the Eternal of Darkness. Originally made to be Eternyas equal, he quickly overpowered her is combat, beginning the first Eternya War. After some fierce battles, he was subdued by the combined forces of Moon, Sun, and a severely weakened Eternya, and he was locked up in the ZERO VOID.
Despite his Element, Darcyan is not evil by nature. He can be somewhat mean at times, but this is unintentional, as Darcyan lacks a lot of social skills.
