Asgard was accepted as apart of the UN and peace came to earth for a time. Asgard was a Utopia compared to earth's cities especially when we worked towards making it look more like the old Asgard. Years passed and Kang the Conqueror came only to be killed after a multiversal war which ended badly for some. The multiverse was repaired and our timeline was set in stone, irreversible from our branch which prevented anymore time travel within our branch of the timeline and reality itself.
Soon a decade had passed since the blip that brought everyone back and Jean lost the Phoenix as an avatar while our daughter Krista became the new avatar of the Phoenix force. Jean's powers were magnified permanently, but just as a metahuman of omega level. Asgard was in a peaceable time while earth was going through sweeping changes. A fourth of earth's population had become powered individuals while the enhanced including Extremis and the super soldier serums had been spread wide.
The Avengers were needed far and wide while the Shi'ar empire had come to war with earth for harboring the avatars of the Phoenix force. The galactic war began and Sword was soon too busy to worry about matters on Earth while Shield was busy dealing with supernatural threats. The young avengers came to be trained five years into the war. Asgard contributed and my children basically all joined.
They'd all awakened Inhuman powers of varying degrees with three having Metahuman powers as well. Kratos proved himself repeatedly in the war and seemed kind beyond words, honest and loved by the people. He didn't want to fight, but did so when necessary because he knew earth and all his people would be in danger if he didn't. The war with Shi'ar ended in a stalemate for a time as the young avengers took over policing the powered individuals who tried to harm earth for various reasons.
Even Banner's daughter the She-hulk herself was a member of the young avengers. Tony's younger adopted brother and real Stark by blood thanks to Tony having been adopted, Arno Stark, was healed from having to use an iron lung with Extremis and now led the young Avengers. I retired when Kratos turned twenty-five and took the throne. The kids were raised, off fighting or having fun in some cases so it was just time in my eyes.
Ironheart, Tony's daughter, was a prodigy and smart enough to make things interesting in the tech business now that the world was extremely advanced. I built more stable two way portals as they were my specialty these days because I understood wormholes, dimensions and teleportation like no one else alive. After that and Tony's help, Morgan and I were able to build a terraforming ship and terraformed a half dozen planets in the Goldilocks zone around appropriate stars.
Humanity soon expanded into the stars as overcrowding had become a thing. Even Asgard had moved out as the city-ship could only hold a million people with it's housing and life support. More city-ships were built for earth's population for the great move. They carried shrunken containers with supplies and people with the right qualifications to begin building a proper colony and civilization.
Soon enough earth's population had gone down by more than half as only a dozen countries remained. Besides China, all the countries shared the planets. China had the largest single population and required an entire planet to themselves or they'd overpopulate the planet too fast before the cities could be built. With less stress on the planet's resources, the cleanup of earth began in earnest.
With technology and magic, I rebuilt the old Asgard but with changes to accommodate the changes it had gone through under my reign. It took several years and a suitable place which was the location of the old Asgard. Thor absolutely loved it when he returned from his ventures outwards with the guardians of the galaxy. Shield and Sword became interplanetary defense and offensive groups for the collective collaboration of worlds known as the fifteen realms.
That included the nine realms from Asgard's domain which already included earth. The six other worlds were just the human worlds we'd terraformed and populated. They were relatively close together by ship and the portals connected them all for easy access. I retired on Asgard where it wasn't too crowded and stayed there for a total of three centuries, having morned all of my lovers except Sif in that time as the Extremis couldn't give them longer and none of them would take the Ten Rings from me over the others.
It tore me apart and because not long after them, all except three of my children passed away and by then I'd had ten in total. My grandchildren and great grandchildren were grown while my son Kratos sat on the throne, Krista as the avatar of the Phoenix remained and Osborn, my son with Wanda who inherited my Metahuman longevity and his mother's talent for magic.
I hid my ring with the gauntlet away the day Sif passed away nine centuries later and stepped into the Dwarves neutron star without a suit on. I wanted to die and yet I only burned a bit around the edges which healed faster than I could burn. I asked Krista to have the Phoenix end me and it tried only to fail because my healing had become absurd. I tried stepping into a black hole next with the ring I had so as to take the stones with me in death only pain was the result.
I didn't die and it enraged me beyond words when I got out. I was about to use the infinity stones only Krista said they couldn't do it because it would've killed me before if they could. In the end I left that reality, looking for one that had something that could kill me when even the celestials tried and failed. The concepts refused to even meet with me beyond the astral plane and said they couldn't destroy my body without altering the laws of the multiverse I was in and they couldn't do that themselves, needing the one above all for such a thing.
I went out of my way to try for an audience with him when Galactus refused to eat me, saying he wasn't interested even when I punched him with the force of all my might in the planet sized head. He hit back and that's how I left that reality, punched so hard I was flung through a tear in reality, through the void and into another reality.
