Genosha:
When you join a group branded by the world the T word to wage a war to take over an island of millions of mutants and about a million humans you don't do it peacefully. We see her depowered at war with a gun for weeks as an insurgent fighting the Magistrates and we see her pitch hitting for Magneto in the long periods he is injured leading the Genoshan Army. The war was a vicious civil war which turned openly genocidal as many historic race wars do.
Genoshan Genocide Fallout:
This is the era where we see Lorna use deadly force on panel for the first time. Lorna pulls the pins on the grenades of anti-mutant religious fanatics and reverses their bullets and frankly isn't about to play on Xavier's terms.
Polaris in space:
The X-Jammers with Lorna and Rachel were less blog standard x-team and more space warriors at war with the Shi’ar Empire.
