I figured that was the case.
Do all the races have a plac ein the default setting?
If so that must be one crowded world.
An answer is complicated...
All of the races have a place OR a time OR a world in the default setting.
In the "now", akin to 1912 IRL, most people are human, though there are other lands over the ocean with hobgoblins, slith, and a few other races here and there that occupy niches.
In the far future, there are other races more in abundance due to medicants tinkering with biological forms and/or people from other worlds.
The world's timeline is organized as a loop. In the distant future, an ark is sent into the far past. The ark was/will be manned by the 5 major races (human, atlan, elf, hobgoblin, and slith). Later, the atlans raise a whole empire, and are decimated. The elves are not big on procreation but they stake their places.
Also, though other races will be created in the future, or come from other worlds, a few figure out how to use the temporal vortex created by the same folks who build the ark. Among those folks, some villages and eventually larger communities survive and spread, albeit never enough to outshine humans.
That's the short answer...
