Azeroth is the name of the world in which the campaign took place in the Tiu'lo universe. The world of Azeroth is the birthplace of many species, most notable being elves (night elves, high elves, and blood elves), humans, dwarves, tauren, goblins, trolls, gnomes, and dragons. Other major powers include the Qiraji, Naga and Argent Crusade. Although ravaged by conflict, somehow through trickery, betrayal, and sheer blood, Azeroth has survived the Axis assault 2 times. However, Azeroth is still torn by conflict, hate, and war, and following the second assault, uninhabitable. The Azeroth Campaign of 1555-1998 took place here of which end result ending in the planet's atmosphere being striped by the Combines though the use of a superweapon created for the single purpose of removing a planet's atmosphere. This forced millions Azerothians to leave the planet to colonized the newly discovered planet some ten systems away, the name of this planet became the memory of the planet they once come from, New Azeroth.
After the First Multiverse War, the Alliance of New Azeroth took control of the planet and now trying to reterraform the planet to recolonize the planet via the Genesis weapon, created by Carol Marcus, however, the Alliance has been having problems with this project.
