Warlord Cassius
From Jenny Everywhere Wiki
Warlord Cassius of the Tharsis Quadrangle was among the people and groups who bid for the venom of the Wyrm of Loki when the Prime Universe's Sigyn decided to auction it off. Like the other bidders, he dissipated like smoke, sent back to his own dimension, after Tero Trollgarsson rendered the auction moot by drinking all the venom, leading Sigyn to interrupt the spell she was using to summon them all. (PROSE: The Winter Quests)
Behind the scenes
The Tharsis Quadrangle is a region of Mars. Cassius is therefore assumedly a Martian.
