The Captain Britain Corps were assembled by Merlyn and his daughter Roma to guard the Omniverse. Based out of Otherworld, each Captain Britain is native to a separate reality, drawing their power from the Omniversal Energy Matrix at the center of Otherworld. A worthy individual becomes Captain Britain after Merlyn and Roma offer them the ceremonial choice between the Sword of Might and the Amulet of Right. All members of the Corps chose the Amulet, but those who chose the Sword were still granted power, merely not accepted into the Corps. One such being named Albion eventually assembled the Shadow Captains for those who chose the way of the Sword.
