Being the X-geek that I am I had to pick up X-tinction Agenda from the Secret Wars event. The title is set in the X-topic domain of BATTLEWORLD and is overseen by Baron Grey (Rachel Grey aka Phoenix). Because it's a four issue auction-packed miniseries it has to stuff a whole lot in each issue; so my receive only gives the basics:
X-tinction Agenda #1
The first issue kicks off with the final battle for Genosha that left Havok and Rahne as new leaders in this country. It fast forwards to years later when the country is plagued by an extinction virus causing them to be quarantined and cut off from the rest of X-topia. There are food riots and the only thing Havoks team is left to do is have Mystique pose as Xavier (who is no dead) to quell them.
The Genoshan leaders plead with both Lord Emperor doom AND Baron Grey but to know avail. The Genoshans believe the with the help of mutant healer Triage and Rogue, under the advice of their gene engineer, could help them stop the plague. Under the advice of Beast, Baron Grey refuses to lift the quarantine.
