Green Lantern Corps
In "Hal Jordan and the Green Lantern Corps" #1, after the events where the Green Lantern Corps found themselves displaced in another universe, Mogo and the other surviving members of the corps find their way back home to their own universe. Thereafter, Mogo also serves as the current headquarters of the Green Lantern Corps. For a period, during the "Prism of Time" and "Fracture" story arcs of "Hal Jordan and the Green Lantern Corps", Mogo also served as the joint headquarters of the Green Lantern Corps (under the leadership of John Stewart) and the Sinestro Corps (under the leadership of Soranik Natu).
