There are a number of diverse races and cultures across Thraea, but the settled lands are predominantly controlled by humans. While it is not strange to see an elf or dwarf outside of their hereditary homelands, it isn’t the norm either except for in the largest of cities. The most common “non-human” travelers are actually hybrids that share parentage with both humans and another race, and typically allow themselves to be mistaken as full human.
The links below will provide information on the world specific races, classes, languages, and time keeping system. If you are looking for more descriptions of the various cultures of the races, those may be found under the pages discussing places.
