In an age without the X-Men, mutants are hated and hunted. The surviving mutants create a last bastion for their dying race: Fortress X. With this AGE OF X, humanity vows to see mutants destroyed and a team of champions find themselves united.

The Avengers have been ordered to find Magneto and his army of fugitive mutants. But when the team is given a license to kill, not every member is up to the task. Who will kill and who will be killed?

In a world where the X-Men never existed, and mutantkind has been hunted to extinction, the few remaining mutants have banded together to make their last stand. They spend each day securing the walls of their stronghold, Fortress X, beating back the anti-mutant forces that would see them wiped out. But when a conspiracy is discovered within Fortress X itself, could it be that mutantkind's last bastion will crumble from the inside out? When the dust settles, no one will be left unscathed.
