Before the self-proclaimed "Galactic Federation" hunts him to the death, Revan was a lone space traveler. Until Susu, a formidable bounty hunter, comes after him. She waits for his bounty to grow until it reaches a considerable sum before handing him over to the authorities. In the meantime, she protects him like a living treasure. Dystopian Future, AI, Mega Death and Rebellion are the terms that represent the world of SPACEM.
