Issue opens with the fanatics of Orchis stationed outside the perimeter of Krakoa. Using a satelite, they manage to link up to the baby machine that Nanny had adopted. Orchis is uncapable of commandeering the infant bot... they are however able to pigback off of it to other machines in Krakoa, notably Nanny's ship.
Sinister and Sinister make it to Murderworld, where Sinister reveals that he's made significant progress outside of the eye of Krakoa via the information procured from Tarn. It's also confirmed that the Locus Vile are Chimera
The Locus Vile manage to slaughter Sinister's clones and Tarn prepares to cruelly torture and kill the Hellions. Kwannon however prevents this by providing Tarn with the information he so desires. Which in turns causes him to leave the Locus Vile to confront Sinister (And create an open portal to Murder World in the process).
Abominal Fetus hungers, and the vile in response become too concerned with trying to quell him that they can't mount a defense/assault on the Hellions.
Kwannon comes clean about the truth to the Hellions and Greycrow snaps, killing the Vile and unintentionally feeding Abominal Fetus. We then learn Fetus is a mutant that comes in four stages and that when it reaches stage four, it will begin to devour time from the universe, unless it's disposed in a Black Hole. This situation causes Tarn to let Sinister go as he can't allow the Abominal Infants destroy the Infants.
The Hellions confront Sinisters from the Portal he created, and we discover Sinister's goal. To create a Sinister with the powers of Tarn, the powers of a reality warper.
The Hellions initially are about to blow Sinister and his facility away, but Psylocke manages to convince them not to by revealing the reason she's been working with Sinister this entire time. That being the hope of resurrecting her Human daughter.
The issue ends with the reveal that Empath is a double/sleeper agent who mind controls alex to destroy the entire Sinister facility while also telling Sinister that Emma sends her regards.
I think I'd like to speak for everyone and say that the most mind blowing parts of this issue are at the very beginning and very end. I also can't imagine the situation is going to be better on Krakoa with what Emma has made Havok do.
