One look at the blood elves and you might think "arrogant pop star," but their story entails much more suffering and tragedy than is at first evident. Like so many in the World of Warcraft, they have very nearly lost everything that was important to them, and more than once their entire way of life has been upset, turned around, and set in an entirely new direction. They are at once brilliant and desperate, beautiful and woefully flawed, addicted to evil magic and yet not yet beyond hope of redemption.
The blood elves are the descendants of the original "Highborne" of the night elves 10,000 years before the setting of World of Warcraft, who used to follow Queen Azshara and studied the arcane magical energies flowing through the Well of Eternity. Following the "War of the Ancients," (discussed in the article on night elves), most of their peers at the time observed that arcane energies tended to attract evil demons from the darkest dimensions in the universe, and thought the world would be better off without it. The Highborne who survived that war had gotten very used to the power of arcane magic coursing through their bodies, however, and they suffered from serious magical withdrawal when those energies were no longer available to them. From their point of view, it was cowardly not to try again, to simply conceal themselves from the demons rather than to give up arcane magic entirely. Their addiction and powerlessness made them desperate enough to turn to violence, though they were no match for the new rulers of the night elf people.
