Well, I don't know who's interested in this buuut I've been making my own setting/world, sort of for fun.
The current name is Eterna, thouuugh I might change it. It is mostly based around magic, freedom, and the ever evolving nature of life.

There are a few base rules and concepts I'd like to stick with.

1. Every intelligent species is an anthro. No humans, elves, dwarves, humanoids like that. You may ask why, well.... Because I like anthros! There is an in world reason i'll explain later. For now, though, civilizations and sentient species are divided into five. Insectids, Cloudseekers, Beastkin, Steelborn, and Seafolk. These, broadly, encompass the five main types of anthros one may find.
Insectids = Insects, most notably, moths, butterflies, spiders, and beetles.
Cloudseekers = Birds, from big to small, with lots of variations, as usual.
Beastkin = Furred mammals, dogs, otters, bears, goats, and a looot of them.
Steelborn = Lizards, Crocodiles, Geckoes, Salamanders.
Seafolk = Aquatic species, these vary a lot... and are basically an underresearched group of species in world too, as it's hard to put them in a single category.
These species and subspecies have lots of similarities and differences. I wanted to be able to have anthros while also making them unique. I'll make a journal on species alone!

2. There are No gods. No physical gods, that is. There are no higher beings capable of shaping the world and of being immortal, even if gods as ideas are still real. This means every creature is free, and in theory, each of them could harness as much power as they could, from other living beings, or from their surrounding.

3. Magic is the force behind it all. Living and non living, all things and creatures. A crystal may harness raw light power, for example, while a type of deer may use it's own magic to adapt to a cold climate. Anthro's use this magic, usually channeling it through them and into the exterior world.

These are the basics, I'll elaborate more later. As you can see, I am missing things like continents, and strict civlizations. The thing is I am not! I just wouldn't want to infodump.
Feel free to give ideas!
