The mutant population has gone from millions to 198 since M-day. Not only have more than 90 percent of them been depowered, but mutants have been killed or mutilated and mangled by Wanda’s spell. The Office of National Emergency (O*N*E) sends manned sentinels to guard the X-mansion—both to keep anti-mutant terrorists like the Sapien League and Purifiers out and to keep the desperate, fearful mutants in. The X-men offer refuge to any mutants remaining. Some of the mutants are chomping at the bit for some freedom because the mansion is being treated as a comfortable prison in the name of safety.
