United Underworld/Outpost Omega
From Unofficial Handbook of the Virtue Universe
Located in the remote recesses of the Shadow Shard, Outpost Omega is the secret, untouchable base of operations used by United Underworld. Floating on a distant rock in the vastness of empty space with built-in defenses manned by a garrison of H.E.N.C.H. Men, the only practical means of entry is by special portal code sequence granted only to United Underworld members.
Upon its conception, teams of H.E.N.C.H. Men were transported to the alternate dimension to begin construction. When trouble arose in the form of Longbow forces, a result of a deception contrived by Nemesis, the villains themselves arrived to eradicate the nearby Nemesis base. When the emptied base then became infested with vermin in the form of the Soldiers of Rularuu, explosive charges were planted to destroy it entirely, isolating Outpost Omega's location from the rest of the Shard.
While far from complete, the base provides an adequate hall for the Council of Chaos to meet. Its continued construction is designed and supervised by the mechanical monster, Autosaurus Wrecks.
