Prince Kael'thas

Prince Kael'thas Sunstrider is a High Elf of royal origins in the fantasy Warcraft Universe.

Being the last of the Sunstrider dynasty, he carried the lineage of the High Elves who were banished from the realm of their kin the Night Elves 9,000 years before Warcraft . Rumors has it that he and Arthas were rivals for the heart of Jaina Proudmoore, a young sorceress and daughter of Admiral Proudmoore of the Alliance. He is the leader of the Blood Elves, a faction of High Elves who, out of desperation to sate their addiction for magic, now draw their powers from demonic sources after the Sunwell, long the source of elven magic, was defiled, along with the rest of Quel'thalas, following the invasion of the Undead Scourge.

He was first introduced four years after the fall of the Second Invasion of the Burning Legion, and was leading a small group of resistance in the heart of the Scourge Plaguelands. There he met Maiev Shadowsong and Tyrande Whisperwind of the Night Elves who were chasing after the Demon Hunter Illidan Stormrage. Kael assisted the Night Elves in thwarting Illidan's attempt to destroy Icecrown Glacier, the citadel of the Lich King Ner'zhul, with a spell that threatened the stability of Azeroth itself.

When the Night Elves left, Kael was summoned to the ruined city of Dalaran, where an arrogant Human commander, Garithos, was leading some of the last survivors of Lordaeron. Kael and his people were treated with discrimination and had no command of cavalry, riflemen, or artillery when requested to take out a large Undead base nearby. The bigoted Garithos, seeing the Blood Elves as expendable, intended to use them as meat shields against the bulk of the Undead forces.

However, a group of Nagas showed up under the leadership of Lady Vashj and offered to help the High Elves in completing their mission. This action only angered the humans and therefore Kael and his men were imprisoned for treason.

At night, Lady Vashj came and rescued Kael and his men, then told him about Illidan's motives, and about acquiring magic, which the Blood Elves desired more than anything else. The Naga and Blood Elves, being descended from the Night Elf Highborne, shared a racial addiction to magic which Illidan Stormrage was more than happy to satisfy.

Kael then joined Illidan in Outland, the remnants of the Orcish homeworld of Draenor that was now ruled by a barbarous pit lord named Magtheridon, who reigned over many demons and the surviving Orcs of the world. Illidan intended to claim Outland as his own world, but before attempting to assault Magtheridon's citadel he needed to disable the numerous Dimensional Gates which the Pit lord relied upon for reinforcements. Kael and Vashj later aided Illidan's assault on Magtheridon's stronghold, and was able to defeat the Pit Lord with help from Draenei guerrillas under the command of the Elder Seer Akama. Before they could celebrate their victory, Kil'jaeden, an Eredar lord of the Burning Legion and Illidan's new master, appeared before Illidan and gave him one last chance to return to Azeroth and destroy Ner'zhul. Kael and Vasj both offered their services as Illidan prepared to assault Icecrown directly.

Kael followed Illidan all the way to Northrend to destroy the Frozen Throne, but Illidan was defeated by Arthas and they fled back into Outland to regroup.

More about Kael'thas and the Blood Elves should be revealed in the World of Warcraft.
