Years later Eimin was seen to be on the ruling council of mutants along with (Cyclops, Storm, Nate Grey) on Planet X. After Havok destroyed the Tachyon dam, Kang came with a team he had assembled to save the Earth. Said the team then attack Eimin to save members of the Unity Squad (Wolverine and Sunfire) that she was secretly torturing, there Kang tells her that every thing she did was part of his plan.
