Age of Heroes MUX is a multiverse comic MU featuring characters from the DC and Marvel universes (and potentially others, at Staff Discretion) early in their lives (but not Year One).

Age Of Heroes picks up not long after the Spectre's curse restricting supernatural influences on the world is lifted, once again allowing heroes and villains to do with their powers as they will. This world is fresh and primed for various influences to begin trying to further their own goals. There are many hooks written into the timeline for potential FCs as well as OCs, and the game world is waiting for players to make their mark.
