Thanks!
Yeah, Deseret is mostly there just to fill out the Rocky Mountains. I filled that part out last. If I would've thought of it I would've put a Deseret in Missouri. I tried with this version of it though to include the more Mormon populated portions of Idaho, Arizona, and the Pacific Northwest. They also got a bunch of the various other chunks of land that were leftover when I filled out the map. No offense taken!
To be honest, I just like exploring the concept of theodemocracies as envisioned by Joseph Smith hence why Deseret shows up.
Most of the world (and heroes and villains that inhabit it) are still in need of fleshing out, but I will do my best. (Also, ignore a good portion of internal borders, they're placeholders for now.)
The POD would probably be sometime in the 1770s, but it is most likely earlier as the French still have some control over the Louisiana territory. That would be when super-powered individuals would appear, like Legatus Americana as an embodiment of the United States. The Confederation of America comes from a division of the North and South of the US between the Free States of the North and the Slave States of the South in the 1830s. Deseret, Texas, and California are all breakaways from Mexico, but the Mormons carve out an empire for themselves. California and Texas help keep themselves from being conquered (and doing most of the legwork during the revolution) thanks to a historic team up between Ursa Major, Ursa Minor, Davy Crockett and Pecos Bill. Louisiana eventually gains independence with the most northern region becoming an autonomous province for the Plains Indians, specifically the Lakota. The Republic of Lincoln is mostly Anglo-Mormon settlers not wanting to be part of Louisiana or the Republic of the Cascades. The Republic of the Cascades is mostly former lumber region, but now is mostly know for having the most supers there (I'm from Washington State, of course I'm going to be biased.) Who they are and what they do is still up in the air. Libertaria is an excuse to have an evil rich business villain who wouldn't break every government regulation in the book.
I know none of this backstory is very historically (or alt-historically) accurate, but it's still in its very early stages of drafts and ideas. I might borrow that idea of a Deseret that exists in a non-Utah location.
