Fall Of X gives readers the end of the Krakoa Era, as the Orchis Initiative has been able to break the power of the mutant nation of Krakoa. The X-Men have been fighting a guerilla war against Orchis, as the majority of Krakoan citizens do their best to survive being trapped in the White Hot Room by Mother Righteous. Things aren't at their best for the X-Men right now, with even some of their most powerful members separated from the team. The X-Men could use a miracle to defeat Orchis.
