The Warcraft universe is inhabited by many races of sentient and sapient beings. These races speak many different languages, have different homelands and racial traits, and can pursue different classes.
Though most races are native to the world of Azeroth, some have arrived from other worlds, such as Draenor. The armies of the Burning Legion are culled from many worlds throughout the Twisting Nether.
In Warcraft lore, race often has the same definition as species. Occasionally, within a race/species are groups called subspecies/subraces
Subraces (aka subspecies) are generally considered lesser groups within a main race/species. However, even these subgroups are considered separate race or species themselves in some sources.
- Dwarf subraces can include Wildhammer, Ironforge, or Dark Iron dwarves.
- The various types of trolls are usually considered separate subraces, though occasionally separate races. The terms appear to be interchangeable to Blizzard.
- Aesir and Vanir are considered two of the titan's various subraces.
