Racial leader

Distinct racial leaders (or faction leaders) for the first ten playable races in World of Warcraft acted as a PvP boss NPC in the capital city of that playable race's faction. World of Warcraft: Wrath of the Lich King added the For the Horde! and For the Alliance! achievements, gained for killing each of the opponent faction's racial leaders. The gnomes and trolls, due to being added late in the core game's development, lacked distinct capitals and had much less involved racial leaders that did not count towards the achievements.

The initial racial leaders were Thrall, Vol'jin, Cairne Bloodhoof, Sylvanas Windrunner, Magni Bronzebeard, Gelbin Mekkatorque, Bolvar Fordragon, and Tyrande Whisperwind, with Velen and Lor'themar Theron being added with The Burning Crusade.

With the game dynamically changing over the course of multiple expansions, not only did racial leaders become more active in the overall plot of the game, many have been outright removed as bosses, and the criteria of the achievements reshuffled.
