Privalia
Risen from the Eternal Sea, via pact betwixt a girl and the Universe. A linchpin in the ever-changing, uncaring depths beyond. Here you will find hope pushing back against the mindless monsters, both sentient and not, that threaten to tear it down, gods that are both human and concept-made-manifest, end-of-the-world prophecies being thwarted by plucky heroes, and magic shaping everything from continent-sized calamities to simple everyday life. Welcome to Privalia.
People
The world of Privalia is home to all manners of creatures both big and small. Most races you'd find in the D&D 5e Player's Guide could be made to work in some way, but the main playable peoples I have are, in no particular order
Monsters
In Privalia, most monsters aren't sentient, but the ones who are either constantly struggle to be recognized by the more 'civilized' peoples as, well, not monsters, or they hide out and live simple lives amongst themselves, trying to not get killed by wandering adventurers. Goblins are the prime example of this, with a solid three quarters or so being sentient and trying to distance themselves from their more blood-thirsty cousins. Often forced to live in shanty towns outside of the proper city walls, Goblins have long felt the cruelty of the other peoples, but they haven't let that stop them from creating a culture all their own. Any monster can be a Person, and therefore can be a player character, but the more monstrous a character is the more difficulty they'll have interacting with other people. Most Towns and Cities won't ban monsters outright, and you'll always find a few monsters living together in any major population, but the smaller Villages and communities, the ones that live with the reality of non-sentient monsters trying to eat them every day, don't take so kindly to people that look like them.
Elves
The Elves are well, elves. Long-lived, pointy eared, live in the forest and keep to themselves mostly. Masters of magic? Well sure, but it's easy to master anything when your life-span is measured in centuries and decades rather than decades and years. To an Elf, you're still a child until you've lived at least a century, and other peoples, except Dragons maybe, never grow past childhood, so most don't have dealings with other peoples because of that. When they're in their first century it's a lot more common for elves to mingle with other peoples, but after their twelfth battle-companion or lover or companion has died from old-age most can't stomach the idea of doing that for a few more centuries, and turn to their own people for companionship.
Humans
Humans are your bog-standard bipedal ape-things, the player is one, probably, and your character can be too!
Flin
Twinned souls bound in two bodies, one of flesh and one of stone, the Flin are what I've replaced Dwarves with, mostly because of the underground mining bit, but also because Dwarves are kinda tolkien-esque anyways and also why not?
The Girl has three names. Gwendolyn, the one her Mother gave her. Ee-Gaspira, the one she took from the Universe, and finally, the common one, the one everyone calls her, the one she accepted when she became something more than herself, Simply~ Privalia.
