Wow, what an issue.
Hank comes back and tells everyone what he saw and how:
The Beyonders are confirmed to be a race and the one that they met just took a human form.
He found the last of the Builders on their multiversal station where they engineered a new Manifold that could get them anywhere.
The Mapmakers were definitely built by the Ivory Kings and they used them as a way to lure others in that would stop them. Though the Builders destroy most of the Sidera Maris and Mapmakers, it was the first part of the ruse.
The Captain Britain Corps captured a Mapmaker and set off a beacon but were wiped out by Mapmakers.
The Builders were drawn into an ambush around along with, ALL THE UNIVERSAL ABSTRACTS. Each Beyonder in all those realities was killing a Celestial Host, explaining why they left the Illuminati.
Eventually the Beyonders killed the Living Tribunal scattering its pieces across all realities.
Hank says to give up all hope as the Gods were killed, so there is no chance for man.
