Isn't that a topic best suited for the World-building forum? Although admittedly, you will get much less traffic.

It's not an easy request to fulfill, given that there often isn't a good starting point.

The primary "schtick" of mine is that monsters are given the spotlight and humans (and most other PHB races) are relegated to the background.

In D&D terms, if you don't have a level adjustment, what are you even doing here?

The other part is, I tried to make it high-magic, without turning it into a tippyverse.

Also, no monocultre races - before it was cool, before all that diversity crap brought on by IRL events that shall remain unnamed.
