I'm working on a story where all the characters are various Undead (we're talking typical D&D Ghosts, Wraiths, Zombies, and Skeletons, albeit with sentience) that all live together in the highly stratified kingdom of Nekros.
Clarifications:
- Corporal and non-corporeal undead exist in this world. Basically, if it's undead, and appears in the D&D MM or MToF for the 5th edition, it appears in this society.
- All are sentient and sapient and capable of some means of communication. Sign language is common, as not all the undead have vocal cords.
- Humans do exist, but they are largely regarded as 'boogeymen' of sorts, a scapegoat the upper class uses to justify the state of things. Basically an "at least we aren't being enslaved/eradicated by the humans" excuse. Either way, humans don't show up with any amount of frequency, and if one did show, it would be the first in the vast majority of people's memories.
- The undead don't decay. They also don't conduct heat well at all. They feel discomfort at either extreme heat or extreme cold.
Basically, I'm wondering if a literal representation of the class-based hierarchy flipped on its head, where the ruling class lives a life of luxury deep underground while the lower class toil near the cold surface above them, makes any sort of sense for a kingdom like this.
