Elysion, with the rest of the soon-to-come Terror Firma, was born in exile on a planet where the United Planets used to dump criminals. Elysion was, together with other superpowered kids there, drafted by Praetor Lemnos to a war to shake the UP out of inaction. Elysion became the leader of Terror Firma, Lemnos' strike team.
Elysion is able to manipulate ground and earth-based material; he likes to use giant hands of stone.
