LOTP Angel Summons! SI

This is kinda an Lord Of The People: I Recruited a Mutant Succubus self insert. If you haven't read the original then you probably won't understand what is going on as I'm not going into to much detail on the explanations. Sue me I was bored as crap.

Also since original doesn't really go into world detail as far as I read such as other countries surviving or rebuilding something different, mine will be based in the United States or what's left of it though it will be in the same universe as the original story, all New Lords Spaces will be transported to the same black fog area, im just expanding the world as the original pretends only Asian countries, maybe only China, survived basically or so it seems to the point I read.
———————————
It has been many years since the old world has been destroyed, there were no longer any of the old countries left standing though new territories arose in their places.

The whole world mutated. Mysterious resurrections happened in real life. The Tribulation descended.
Everyone would awaken the ability to rule over beasts at the age of 18 and obtain a Lord Space of their own. After one month, their Lord Space would materialize and they would become a Lord.

When they awakened, each Lord would obtain a summoning pool to summon their own troops a month before their 18th birthday. They had to plunder resources, strengthen their troops, expand their territory and defend themselves against the invasion of demons!
