Warcraft Encyclopedia: High Elves and Blood Elves

High elves and blood elves are physiologically the same race, and they are descended from night elves. Nevertheless, due to their shared history and philosophical differences, the three groups do not share a close relationship. Indeed, night elves regard high elves and blood elves with suspicion, disgust, or outright hostility.

Elves in General

Elves do have several characteristics in common. All three groups have unusually acute senses and are able to see clearly even in low-light conditions. As a general rule, elves are also slim, athletic, and graceful. Furthermore, they all have large pointed ears that tend to be greeted with admiration or mockery by other races.

One similarity between night elves, high elves, and blood elves has only recently come about. The night elves sacrificed their immortality and much of their power at the end of the Third War. Thus, all elves are now mortal and have comparable lifespans that can extend as long as several thousand years.
