Ellis and Bianchi's first issue, Astonishing X-Men #25, featured the team relocated to San Francisco, with a base in the Marin headlands. The story takes place in the aftermath of the "House of M" story arc, which put mutants on the verge of extinction. The initial "Ghost Box" arc was printed under the "" label, but did not feature any crossovers with other titles. The only addition to the team was Storm, with Colossus and Kitty Pryde having left the team.
