I'm working on a new setting for my first 5E campaign, sometime in the distant (but hopefully not too far) future.
The world has had a cataclysmic invasion by elves and lesser fey (gnomes, goblins, etc.) and the only safe places from them for humanity to live in are within the territory of dragons. It's been a few generations later, and the dragons are encouraging humanity to strike out and reclaim their old lands.
Humans aren't the only ones wanting to kick out the elves, as the dwarves have been holed up in their delves, and the orcs, goliaths and other Bulky Folk have maintained their own lands still, but are starting to waiver. Halflings have gotten by purely because they escape the fey's notice due to their crafty nature. And new people have also arisen though, the various fey touched and the dragonborn, and both bring sorcery.
There are a number of factions (and associated Icons, borrowing that design element from 13th Age) that (almost) all agree that the elves should be removed, but with enough disagreement about other issues to make things Interesting.
Game play I'm thinking will be sandboxy hexcrawling, with plenty of Old Kingdom ruins (and armories) to find and loot, as well as fey dwellings. Also the occasional young dragon to help establish a new lair & town.
The fey touched will be using the PC stats for elves, half elves, gnomes, and maybe tieflings and genasi. I'll probably use both the regular dragonborn stats and the aarakabirdthing's stats refluffed to be draconic. I haven't decided if they're just a change on humans due to living so close to dragons, or the more classical half-dragon route, though I am leaning towards the latter.
Dragons are not color coded, particularly in regards to alignments but also for abilities and general personalities, and they're about as variable as humans are.
I've got more details in a
