Graymalkin
Cable's base in space assembled with technology from his future timeline. SHIELD attacked it and partially destroyed it, sending several parts of it to Earth. Magneto later reformed it into Avalon.
Named after the Xavier Institute's address, Graymalkin was operated by the Professor, Cable's sentient computer that was formerly X-Factor's Ship, and later became Prosh. It had technology allowing Cable to teleport or bodyslide as he called it as well as a timecore that allowed for time travel.
