For the fourth city introduced in the Four Cities saga (see the three prior issues), we go back to the Negative Zone. Human Torch tells Valeria the story of how he was recently lured there (and if you’ve read ahead, you know that he’ll be tied to the Zone in later Hickman issues)

Valeria notes that this is the fourth city from her brother’s prophecy of a coming war.

Johnny was reckless (as usual) in going into the Zone by himself, so Reed gives him a scolding.

There’s also a check-in with Susan Richards in Old Atlantis, as she greets a diplomatic representative of Namor’s Atlantis, and with the Inhumans as well as a team of warriors from each of the races who now dwell there (called the “Light Brigade”) also go to the Negative Zone–apparently on a suicide mission–and begin the “War of the Four Cities.”

The reasons for the war are as yet unknown.
