The floating headquarters for the mutant group, the Acolytes, which has since been destroyed.
History
Avalon was salvaged from parts of Cable's ship Graymalkin. X-Force deceptively destroyed Graymalkin after S.H.I.E.L.D. attempted to invade it and use it for their own purposes, but most of its critical parts remained cloaked or within X-Force's possession.The mutant messiah Magneto later acquired several parts, eventually building the mutant sanctuary Avalon, a haven for mutants that floated in space. The base became headquarters to Magneto's group the Acolytes, including high ranking member Exodus. While Exodus tried to recruit Magneto's former students from the New Mutants (who were now part of the Cable-led militant group X-Force) to stay in Avalon, Cable returned to his former ship and tried to destroy it.
Unfortunately, the ship was later destroyed when Onslaught attacked the base leading to it crash landing into unknown parts of Australia. Many members of the Acolytes died, but several--including Exodus, Scanner, Frenzy, the Kleinstock brothers, and Unuscione--were able to survive.
Ironically, Avalon's parts once again came into the possession of Cable, who used the remnants of Avalon to build his isolated island nation Providence.
