With most of the original X-Men team trapped on the sentient island Krakoa, Professor X recruits new members to rescue them alongside mainstays like Cyclops, Havok, and Lorna. By combining her abilities with those of her fellow X-Men, Lorna is able to reach incredible new levels of power, and launches the living landform into orbit!
Havok leaves to check in with the X-Men, leaving his paramour Polaris alone at their homestead. However, the Marauders are also there, stalking Polaris from out of sight, and she has to take on Sabretooth, Arclight, and Scalphunter singlehandedly! But in a shocking twist, the evil mutant known as Malice was in control of Polaris the entire time, and was testing her abilities against the Marauders.
After finally freeing herself from Malice’s possession, Polaris is almost immediately kidnapped by Savage Land priestess Zaladane, who claims to be Lorna’s sister. Spirited away to Zaladane’s Antarctic homeland, Polaris’ best chance of liberation lies with Havok, who infiltrates Zaladane’s army in disguise.

While still reeling from the loss of her powers in the wake of House of M, and anxious over recently revealing that fact to her teammates, Polaris encounters a mysterious being called Daap that only she could understand.

Magneto discovered his young daughter in the aftermath, and had Mastermind rewrite Lorna’s memories.
