The setting of the "Going Rogue" expansion was Praetoria, a parallel dimension version of Paragon City where the world was ravaged by Hamidon and his Devouring Earth legions and only Emperor Marcus Cole managed to bring stability to a world ravaged by the Hamidon Wars. Superpowered individuals living in Praetoria begin as Praetors, working for Emperor Cole, but decide to either join the Loyalist faction and remain a member of the Praetorian armed police force or join the Resistance and attempt to reveal the corruption of Emperor Cole (otherwise known as Tyrant) and free humanity from his rule.
