Cassandra Nova Xavier was an Omega-level mutant and the twin sister of Charles Xavier. Being banished to the Void by the Time Variance Authority, Nova took a liking to it and gained permission to run her operations there as she pleased, building an armed community of survivors.

”So… your timeline was terminated too huh? What’s… your name?”
