Just spoilers; I don't know when, or if, I'll ever finish the Arakiel book; this is just the basic summary of whats left that I would be using as the basis if I ever got it started up again.
In Arakiel's universe, Lightning and his cousin Steven get into a deathmatch under the influence of Hate's aura. Lightning dies because he was strong-willed enough to hold back. Shame, he seems to die in most universes. Doctor Disaster has been working on a machine to transfer himself into a new body; and has been spending decades both perfecting that machine, as well as working on the technology to build himself the perfect body; his primary motivation for everything. He's given the opportunity to take a grieving, depressed Steven's body, and does so; learning as he does that Steven wanted this to happen.
Loki and Arakiel are already on the way to stop him when Hate triggers the artifact; and this time, Loki's able to immediately suborn the ritual, steal hate's power, and crush him. He initially just flat shuts-off the artifact, but Odin asks him to turn it back on and push out something other than rage; billions of people are dying, and he hopes to slow or stop this. His initial attempt to replace it with joy only amplifies things; while swapping it with sorrow drags it to a stop. When the event is over, and the false emotions die out, Loki has absorbed billions of people worth of life energy, and knows that its probable that most of humanity is gone.
As they start cleaning up from the disaster, and the recorded death toll is determined to be almost two thirds of the human population from the event now simply called the Rage, they learn that the preparations in orbit have also fallen apart; the ships to get a remnant of humanity to another star, the ships to defend humanity against the Jotun; all gone. Mining operations in space can still continue; but the facilities in earth orbit to build ships are ruined.
When a corporation on the west coast takes delivery of a shipload of old russian super-tech not long after the disaster, the corporation discovers 'Dark Ascension'; and decides to reprogram it as best they can, and try to build their own group of machines to help rebuild.
The reprogramming is a failure; the machine is damaged, much of its core programming removed, but is still a sentient being; just without its primary directives. It escapes; and, damaged, goes on to build itself manufacturing facilities in secret.

Years later, Apollo and Arakiel meet again in the ruins of a city destroyed by the war between Dark Ascension and humanity. They discuss the new future they see; a humanity already broken and fallen, with most of the world ruled by an AI overlord and resistance mostly pitiful, only for the Jotun to easily conquer them on arrival. They don't see anything they can do to prevent it; the only reason the AI hasn't already won is thanks to Doctor Disaster's new powers; their foresight became ever more convoluted and worthless as a handful of precognitive children were born thanks to the artificial insemination with Arakiel's sperm. They have a discussion. Apollo contacts Doctor Disaster and brings him in; and suggests doing something the doctor believes is impossible; building a time machine to go back and prevent the events from ever happening. Insisting it can work, but that Hephaestus refuses to do it, he gives Disaster everything he needs; and suggests a three-person team go back in time; Arakiel, Disaster himself, and Loki.
Disaster builds Apollo's machine; and at Apollo's request, moves it to the middle east; a set of coordinates Arakiel recognizes as where he got shot in the head. As he activates it, Disaster realizes what the machine actually is; a device that will take whoever is there and send them to another universe; it was Apollo's plan to send them to a universe that was earlier in the timeline, dooming his own universe but sending the best three people he could think of to save the future.
Disaster decides Apollo's plan is interesting; but that he didn't think big enough. Shutting off the machine, he takes advantage of his own effectively infinite speed and travels the globe; building a series of devices scattered around the world. Over the course of a few hours, he gathers together millions of people; literally handing out leaflets asking them to raise their hands if they wanted to go; and after collecting a mass number of volunteers, triggers the devices.
The initial device works exactly as Apollo planned; Jason Bennet from the new world is gone, as is the metahuman he was killing; with Arakiel and Loki taking their place. And in orbit of the planet, a series of stations suddenly appear; carrying millions of refugees of a fallen earth, having left the world doomed to death at the hands of either the Jotun or the machines to die... supposedly.
Disaster builds one last machine as an escape hatch, just in case... before digging in to use his mind and powers to fight both the machines and the Jotun with the help of those who remain; without as many civilians to worry about he's confident he can handle it.
This is then revealed to be the new universe Eyeball was sent to when he arrived in Andromeda. When he finally gets back to earth, he's greeted at a defensive space station by Loki, in the guise of a superman-like figure defending the earth, and of course, gets to meet himself. Exactly what led up to his arrival back at earth will, of course, be in the Galaxy of Death book.
