History
Storm along with several other X-Men stopped N'astirh from opening a portal to Limbo and releasing a swarm of Demons. However, unknown to them, S'ym had absorbed N'astirh's power and joined forces with Madelyne Pryor. The pair surprised the X-Men and their combined powers killed Storm along with several other X-Men.[1]
