The computer games were the origin of the Warcraft universe, and continue to be its primary focus. Much has changed in the lore since Warcraft: Orcs & Humans, with each new release greatly expanding the world and revising some of the past lore.

Warcraft I introduced the basic conflict between the orcs and humans, as well as the characters of Medivh, Llane, Garona, and Lothar.

Warcraft II expanded the world beyond the continent of Azeroth to include Khaz Modan and Lordaeron. The dwarves, high elves, trolls, goblins, and Burning Legion were introduced, as well as a host of new characters.

Warcraft III expanded the world yet again by introducing the continents of Kalimdor and Northrend, a detailed backstory chronicling the creation of the world of Azeroth, and several new races including the night elves, the tauren, and the Scourge.

World of Warcraft has continued this trend by allowing the players to experience nigh all of the colossal world as no more than one of the many little players.
