Mercurius strives to achieve the unknown, not because he wants to learn more, but because he is hopelessly bored. He naturally possesses a relaxed, calm and manipulative demeanor, something that infuriates virtually everyone that he come into contact with. He is also philosophical and poetic and has a tendency of speaking for long periods of time.His true identity is the Hegemony God of the fourth heaven, who became tired of eternal recurrence and began to seek his own end.
