Fantasy Story Idea

So like, I imagine this. What if there were 3 dimension. The Overworld, The Middle World, and the Underworld. The overworld is inhabited by all the “happy little whimsical” creatures reside (gods, fairies, mermaids, angels) The Middle world is where Earth resides, and the Underworld is where all the “nasty” creatures lie (demons, vampires, werewolves, sirens).

            At some point 1000’s of years ago certain overworlders decided to take underworld territory. These beings were the gods associated with the underworld in ancient mythology. There was a war that took place between their forces and the underworld forces, but eventually, they underworlders were defeated and had their homes taken from them.

In this world all races, cept those in the middle world have a certain way their societies are based on.

The Royals, are essentially the rules of a certain clan/group of a certain race. They possess no known weaknesses and the only way to kill one is decapitate them.

Soldiers. These make up the army they possess no weakness but they don’t possess a natural immunity to certain things

Citizens are the same except they are not soldiers

A Royal, soldier ,citizens powers depend on whatever race they were born into. But they mostly possess the same things

Royals have ultra-advance regeneration, their strength levels are in the 1,000s of tons  and they are super quick

Soldier’s strength levels are in the 100s but usually are class 75-100 and have good regeneration

Citizens Strength level range from 20-50 tons range

So it should like take place in the modern world, with remnants of the underworld army trying to take back their homes form the overworlders.
