The Scarlet Crusade is a faction in the World of Warcraft universe, primarily composed of humans dedicated to eradicating the undead and the influence of the Scourge. Formed during the Third War, they are known for their zealous and fanatical approach to combatting the undead, often leading to extreme measures and intolerance towards anyone they perceive as a threat. Despite their noble intentions, the Scarlet Crusade has faced criticism for their methods, which can include violence against innocent beings. Their stronghold is located in Tirisfal Glades, where they maintain a presence in various locations, including Stratholme and Andorhal, often clashing with other factions like the Horde and the Alliance.
