As the centuries passed, the night elves' new society grew strong and expanded throughout the budding forest that they came to call Ashenvale. Many of the creatures and species that were abundant before the Great Sundering, such as furbolgs and quilboars, reappeared and flourished in the land. Under the druids' benevolent leadership, the night elves enjoyed an era of unprecedented peace and tranquility under the stars.
However, many of the original Highborne survivors grew restless. Like Illidan before them, they fell victim to the withdrawal that came from the loss of their coveted magics. They were tempted to tap the energies of the Well of Eternity and exult in their magical practices. Dath'Remar, the brash, outspoken leader of the Highborne, began to mock the druids publicly, calling them cowards for refusing to wield the magic that he said was theirs by right.
Malfurion and the druids dismissed Dath'Remar's arguments and warned the Highborne that any use of magic would be punishable by death. In an insolent and ill-fated attempt to convince the druids to rescind their law, Dath'Remar and his followers unleashed a terrible magical storm upon Ashenvale.
The druids could not bring themselves to put so many of their kin to death, so they decided to exile the reckless Highborne from their lands. Dath'Remar and his followers, glad to be rid of their conservative cousins at last, boarded a number of specially crafted ships and set sail upon the seas. Though none of them knew what awaited them beyond the waters of the raging Maelstrom, they were eager to establish their own homeland, where they could practice their coveted magics with impunity.
The Highborne, or Quel'dorei, as Azshara had named them in ages past, would eventually set shore upon the eastern land men would call Lordaeron. They planned to build their own magical kingdom, Quel'Thalas, and reject the night elves' precepts of moon worship and nocturnal activity. Forever after, they would embrace the sun and be known only as the high elves.
