World of Warcraft, or WoW, is set in a fictional universe, its primary setting being the planet of Azeroth. The first expansion, The Burning Crusade, introduced a second planet, Outland. Wrath of the Lich King and Cataclysm expanded upon Azeroth and respectively added Northrend, the frigid northern continent of Azeroth, and drastically changed various other continents by destroying some and unveiling new ones. The next expansion, Mists of Pandaria, added Pandaria, the southern continent previously hidden behind a perennial mist cover. Warlords of Draenor introduced the planet of Draenor, a version of Outland in a different timeline before its partial destruction. The Legion expansion took adventurers to the Broken Isles, an island chain near the Maelstrom in the middle of the Great Sea, and the damaged planet Argus, the headquarters of the Burning Legion. The seventh expansion, Battle for Azeroth, added two new island continents to the center of Azeroth: Kul Tiras and Zandalar. The latest expansion, Shadowlands, introduced the eponymous Shadowlands, a realm composed of five major zones: Bastion, Maldraxxus, Ardenweald, Revendreth, and the Maw.
