Due to the reckless channelling of the vast amount of magic the High elves wielded during the pinnacle of their empire, the High elves developed an insatiable thirst for magic; this addiction, if not fed, will eventually result in insanity, then death. Previously the source from which this thirst was fed was from their beloved Sunwell; a vast magical fountain constructed on an underlying node of power. The Sunwell was one of the most powerful magic artifacts in all of Azeroth. Radiant with magic power, this artifact fed the former High elves with unimaginable magic. One dreadful day, however, the High elves were severed from the source of their magic and as a result, they suffered indignities and fell into darkness. In the High elves’ darkest moment, Kael’thas Sunstrider, the last of the Royal bloodline gathered the last of the remaining High elves, renaming them Blood elves in honor to their fallen brethren. He then proceeded to teach them how to tap into other ambient magical sources, feeding upon it to sustain themselves temporarily.

After the Blood elves joined Illidan and the Naga, they were granted powerful demonic magic that not only sustained them, but strengthened them as well. They now revel in the source of their dark powers and have regained much of their former strength. More reckless then ever before these Blood Elves will stop at nothing to gain power, regardless of the costs. While the dark magics they now wield are enough to sustain them, the Blood Elves always look for more ways to boost their own power and do not hesitate to ruthlessly exploit any magic wielding creature, feeding upon its essence until only a shell remains, devoid of all life.

Their ‘thirst’ for magic may be noticed in The Burning Crusade game, which allows Blood Elf players to play as nearly all of the mana-based classes: Warlock, Paladin, Priest, Mage and Hunter. The Druid and the Shaman are absent from this list, as the Blood Elves long turned away from the naturalist ways of their Night Elf kin, and want nothing to do with the druidic culture, believing only in their race’s fortitude.
