Аман'Тель Эверватч

These exiled Highborne, now known as the high elves, took their punishment in stride, and led by Dath'Remar Sunstrider ("He who walks the day") set sail across the ocean in hopes of finding a new land to call their own. After a long and perilous journey, the Highborne arrived in the land known today as Lordaeron, and there established their kingdom of Quel'Thalas ("high kingdom" or "high home") and crowned Dath'Remar their king. There, they slowly changed in form, diminishing in size and losing their original purple skin to a pinkish hue. They abandoned the worship of the moon, adopting instead the sun, and became the high elves. They remembered the mistakes of the past and used Runestones to shield their use of the arcane from the Burning Legion, taking care to practice the magic granted to them by their Sunwell with more care than their ancestors. Nevertheless, after their homeland of Quel'Thalas — and the source of their power — was destroyed by the undead Scourge, a radical group of high elves embraced their Highborne ancestry and resumed for the third time their reckless use of magic. Kael'thas Sunstrider renamed these people as the blood elves, and traveled to Outland with Illidan to find a way to fuel their magical addiction. Those who did not travel with him remained behind and began to rebuild their shattered capital city of Silvermoon.

Здесь мы видим, что после прибытия в Лордерон высокорожденные постепенно изменялись физически (рост, цвет кожи), отказались от ночного образа жизни, присущего калдореям, перешли на солярный ритм существования. Если для вас подобные изменения не являются признаками формирования нового народа, то было бы интересно узнать, что же вы считаете таковыми.
