Race is acknowledged and important, but the role it plays is more that of our society race rather than fantasy race. No race in the world is evil per se. Some (the yuan’ti particularly) do claim that all others deserve to be their slaves. And the orcs are very brutal. It’s still as a race being evil, and the dislike of drow is more similar to a dislike of Germans after World War 2, rather than a certainty that drow are evil forever.
For this world, race works slightly differently. Some species are too different to have viable offspring, however many species can interbreed. In the vast majority of places, the offspring ends up being more one race than the other, with one set of racial characteristics being dominant, with perhaps some traits from the other parent. For example, a Tiefling and an Elf could have a child. The child might be nearly entirely tiefling, but may have pointy ears, or live a surprisingly long time and age slowly.
Below are links to each race’s individual page in the wiki, divided up by their native region.
Note: Currently only playable races are listed below. There are more races on the continents (particularly Katsina) that are not listed here yet.
