After the X-Men are chased out of their new base in San Francisco by Norman Osborn and the Dark Avengers, in the conclusion to the Dark Reign storyline Utopia, Cyclops sets up the new headquarters and mutant sanctuary on the ruins of the original Asteroid M which was raised from the bottom of the ocean. Christening it "Utopia," this version is more of a haven than a base of operations, brought on not by a desire to make a place among mankind, but to simply get away from it.
The island first appeared to be in trouble of only being a temporary home as the technology keeping it afloat was not stable and the island was starting to sink back into the ocean. However, the X-Men were able to broker a deal with one of their newest members, Namor, in which he and his people would help construct a pillar underneath the island, connecting it to the ocean floor and keeping it afloat. This pillar would also serve as the new home to the Atlanteans, who had been scattered across the sea ever since Atlantis was destroyed.
