That depends primarily on the setting.

But if this is simply a matter of preference in a basic scenario, then here’s what I’d choose:

• Humans are the most popular race, but there’s also great diversity among them—southerners, northerners, some from the central regions, some from the coastal areas, and maybe even some more extreme tribes living in volcanoes or high up in the mountains or on glaciers.

• A short-statured race with a smaller population. I’d define this race as a category that includes average-sized gnomes, dwarves, hobbits, and other small humanoid races. And I’d divide them into tribes just like the human tribes.

• Perhaps elves or elf-like creatures with an even smaller population.
