Northrend is the northern, icy continent of the world of Azeroth, and the source of the evil Scourge. It is also the home of Icecrown Citadel, the seat of the malevolent Lich King. The continent is featured in the World of Warcraft expansion, World of Warcraft: Wrath of the Lich King.
Often called "the roof of the world" and sometimes "the crown of Azeroth", Northrend is a frozen wasteland that lies far to the north. As with the other continents, it was once part of the original Kalimdor landmass that was broken apart during the Sundering. The land that became Northrend drifted far from Azeroth's temperate zone, which killed off a large portion of the remaining wildlife.
