World of Warcraft: The Burning Crusade: Fury of the Sunwell

Patch 2.4.0, titled Fury of the Sunwell, was a content patch that released on 25 March 2008.

Fresh from his defeat in Outland, Kael'thas Sunstrider returned to the blood elf city of Silvermoon. Rather than lead his people to glory as he had promised, the disgraced prince betrayed them. Kael'thas plotted to use the legendary Sunwell, source of the blood elves' magical power, to summon the demon lord Kil'jaeden into Azeroth. Aided by a joint task force of blood elves and draenei, the Shattered Sun Offensive, Horde and Alliance heroes narrowly stopped both Kael'thas and Kil'jaeden, purifying the Sunwell with the help of the draenei prophet Velen.
