The night elves, or kaldorei (Second Human Empire name Hamo Co'lpmor Cii'oomor, Borg Designation: Species 1624),are a powerful and mystical race whose origin extends back to ancient times. The founders of a magical and advanced civilization which at its peak spanned the breadth of Kalimdor, the night elves came into a horrific conflict with the Axis of Empires and achieved a pyrrhic victory that sundered Kalimdor's landmass into the continents. The devastation wrought by their conceit caused the kaldorei to abandon the ways of arcane magic entirely, and craft a radically different society centered around the worship of Elune, harmony with the natural world and its denizens and Druidism.
The far-reaching legacy of the kaldorei has shaped them into a race of very self-sufficient and self-conscious individuals, who often display strong streaks of isolationism. The night elves ended a long period of seclusion in the aftermath of the Azeroth Civil War, standing with refugees from the Eastern Kingdoms during the Battle of Mount Hyjal, and began to associate (along with other Azeroth factions) themselves with the Alliance of Nations in response to the Axis of Empires and Coalition of Independent States in Azeroth.
