Elf

The Elves are one of the most ancient and powerful of all the intelligent races of the Warhammer World. They are tall, slender humanoids who are inherently magical and live for millennia. There are three main factions of Elves in the world: the High Elves, Dark Elves and Wood Elves. Compared to humans, Elves are taller on average, fair-skinned, and slender. They possess high cheekbones and slightly angular faces and slanted eyes. Some depictions show them with completely black eyes, while in others they possess human-normal pupils and irises.
High Elves are often shown with blonde hair, Wood Elves with brown and Dark Elves with black, but these changes are minor and cosmetic and the three groups are for the most part physically indistinguishable and all members of the same species. What defines each kindred of Elves more than anything else is their different cultures.
Assuming they do not die a violent death, Elves are capable of living for several thousand years. It is not considered impossible for an Elf to live seven thousand years or more, although only Malekith, the Witch King of Naggaroth, could claim such an achievement at present. Most often an Elf will not die of old age in the human sense, rather he or she will simply grow weary of the world's troubles and lose passion for life, eventually slipping away into death.
Elves are inherently magical, and their long lives provide magically-gifted elves more than enough time to train their skill at controlling many of the Winds of Magic. This is in contrast to human wizards, who can usually only hope to wield one form of magic during their lifetimes. Elves are resistant to disease and to physical mutations caused by Chaos, although notably they are still vulnerable to Nurgle's Rot.
There is also some evidence that Chaos can affect Elven minds in more subtle ways. Elves experience emotions and thoughts more intensely than most other intelligent races. At best, this can result in them spending centuries obsessively training or honing a skill to perfection. At worst, they can become "lost" in their experiences, over-indulging and losing track of reality, which makes them a favoured target of corruption by the Chaos God of pleasure and excess, Slaanesh.
The High Elves of Ulthuan — the Asur as they name themselves — are not the only race of Elves to walk the world. The truth of the matter depends on who is telling the story; however, they do hold the honour of being the one true civilisation from which all other Elven realms have sprung. West of Ulthuan, amidst the crags and spires of Naggaroth, dwell the cruel Dark Elves, the Druchii. There is no peace to be had between the courts of Ulthuan and Naggaroth, for the millennia of their shared history have been of endless blood and betrayal. No enmity in all the world is so bitter, no war so savagely fought.
By contrast, the Wood Elves of Athel Loren hold no enmity for either their High or Dark Elf cousins, but then neither do they nurture any great trust of them. These Asrai possess a manner and outlook that is utterly alien to other Elves, and want no part of the ancestral hatred that has brought only ruin to the world. Regardless of their bloodline, all Elves are long-lived — some say immortal. Physically, they are tall and slender, with a dexterous grace and otherworldly aspect that no other race can aspire to match. Such traits are shared by all three races, although the High Elves would have you believe that only on Ulthuan can true Elven beauty and warrior grace be found.
