*In Space
From outer space, the three X-Men blast into the Starjammers ship. Its crew begins to transform into their true selves, green war Skrulls.
Lila and Deathbird teleport to a ring of asteroidal rocks called the Maul. They came here after the real Professor X put a suggestion of coordinates into Lila's mind. Here is where the Skrulls have their genetic matrix. *Source: Back of card
