Edited on 10/17/20 because new info

This dimension is largely the same as 416, except for a big difference:

How it turns out in the long run.

In 416, Loki and Olivia's rule lasts for the better part of the rest of their lives, meaning they stay in power with no opposition. Their children inherit the throne eventually (that, I have no idea how it would go after).

412 is a little bit different.

About 11 years after their success (because it'd be 2023 lol), a small group of insurgents create a plan to take back their home.

I call them the 'B List' Avengers cause Idk what else to call them.

The team consists of:

~Wanda Maximoff
~Pietro Maximoff
~Bucky Barnes
~Peter Parker

As well as two other faces:

~Carson Ambrose
~Maya Adams

And they request help from their only hope:

~Thor Odinson

Once this squad and the entire freakin Asgardian Army show up on Earth to take back control, it's an all out war.

The Avengers and the Asgardian Army, plus Odin and Frigga

Vs.

Loki and Olivia and their army provided by Thanos (cause he was pleased they suceeded, so he sends whatever they need to keep Earth).

Obviously, Loki and Olivia lose. They're taken back to Asgard to be locked up in the dungeons (Dark World Loki style) while Earth rejoices it's freedom, thanks to the Avengers. Nat, Steve, Bruce, Clint, and Tony are freed from their mind control as well during this.

Now, Asgard

Odin wants the death penalty because he's Odin and a certified douche (but, also, justified because that was like the ultimate crime against the universe). Frigga shuts the idea down because she's Frigga, instead deciding on something closer to life in jail unless they're released by trial. And, of course, she lets Olivia and Loki share a cell because she's just that awesome.

Then, three standard Midgardian years in incarceration, someone sneaks into Asgard to let Loki and Olivia out. It's one of Thanos's children, Proxima Midnight, come to take them to the Mad Titan. You know, the blue haired woman(??) with horns.

Anyways, Loki's been under Thanos' control for so long that eventually, his old state of mind was completely destroyed. His new default is power, vengeance, ruling, and his love for Olivia (cause that transcends everything, though she's also in the same state of mind).

The two of them, plus Proxima, escape Asgard without raising any alarms.

Thanos is surprisingly understanding towards the loss of Earth, probably because in the long run, he still got what he wanted: the Infinity Stones he was after.

Thanos takes Loki and Olivia in to become Children of Thanos, just for the drama aspect.

About three years after that, Olivia gets the idea to try and take over Asgard (in reference to Amora's plan in the Loki book). Thanos agrees to it for the idea of a nine for one deal (Because World's Tree) plus the chance of finding the Aether. Planet after planet falls under their control to collect resources and troops, Loki and Olivia even going as far as to return to Jotunheim for their support in return for peace.

Then they basically sneak into Asgard, take out the leadership by banishing Odin, Frigga, and Thor to Midgard indefinitely, then send in the troops. It's very easy because without direction, Asgard's army doesn't know what to do.

Baby spoiler, but then Olivia and Loki betray Thanos in the end, killing him so they have total control over the Stones, the Realms, and the Army.

***

Key events for the dimension to exist:

~The Maximoff Twins plus Carson escape captivity (Bucky escapes his HYDRA base on his own)

~Thor answers the call for help (along with the rest of Asgard)

(The stuff after the Avengers take back Earth involves a lot of stuff happening, so draw your own conclusions).

This dimension seems like there are a lot of scenarios that can be formed. It's like my sandbox where the depth of Olivia and Loki's evil can fluctuate a lot.

I never expected this dimension to be so interesting for me, and yet I've been writing more and more chapters for it to do some world building, specifically the 11 year reign on Earth. And, yes, I sort of made 412 an honorary main/base multiverse, but not completely because it branches off of 418/419/416 and isn't it's own thing.

413 is next. Not as deep winded as this one (at least I hope not)
