The Citadel

A thousand years ago, a group of galactic heroes banded together to battle evil and injustice across the stars. Known as the Citadel for their asteroid fortress, given to them by a Karnak Emperor, they dealt with threats like the D'Harque and the Shadowlords. The banner of the Citadel has brought hope to the hopeless for nearly a millenium since.

The Citadel maintains a corps of heroes, known as the Citadel Guard. Several Earth heroes have joined their ranks, including Power Man and Falcon.

Several years ago, the original asteroid base was destroyed in a cataclysmic battle with the Karnak Imperium. In the course of the fight, many of the Citadel's greatest heroes were slain. The survivors regrouped and rebuilt a second Citadel as an orbital habitat, which, equipped with hyperdrives, can travel freely between the stars when needed.
