Sanctum

The Centurion’s sanctuary and headquarters, hidden under the ice caps near the North Pole (and the hidden city of Ultima Thule). The Sanctum is, among other things, a monument to the Centurion’s lost home world, and now a monument to him as well. It contains an arsenal of advanced weapons and a menagerie of alien creatures as well as the Centurion’s original dimensional life-pod. Heroes sealed up the Sanctum after Centurion’s death.
