The stubborn elves, unwilling to give up their new land, utilized the magics which they had gleaned from the Well of Eternity and kept the savage trolls at bay. Under Dath'Remar's leadership, they were able to defeat the Amani warbands that outnumbered them ten to one.
Some elves, wary of the Kaldorei's ancient warnings, felt that their use of magic might possibly draw the attention of the banished Burning Legion. Therefore, they decided to mask their lands within a protective barrier which would still allow them to work their enchantments. They constructed a series of monolithic Runestones at various points around Quel'Thalas which marked the boundaries of the magic barrier. The Runestones not only masked the elves' magic from extra-dimensional threats, but helped to frighten away the superstitious troll warbands as well.
As time wore on, Quel'Thalas became a shining monument to the high elves' efforts and magical prowess. Its beauteous palaces were crafted in the same architectural style as the ancient halls of Kalimdor, yet they were interwoven with the natural topography of the land. Quel'Thalas had become the shining jewel that the elves had longed to create. The Convocation of Silvermoon was founded as the ruling power over Quel'Thalas, though the Sunstrider Dynasty maintained a modicum of political power. Comprised of seven of the greatest high elf lords, the Convocation worked to secure the safety of the elven lands and people. Surrounded by their protective barrier, the high elves remained unmoved by the old warnings of the Kaldorei and continued to use magic flagrantly in almost all aspects of their lives.
For nearly four thousand years the high elves lived peacefully within the secluded safety of their kingdom. Nevertheless, the vindictive trolls were not so easily defeated. They plotted and schemed in the depths of the forests and waited for the numbers of their warbands to grow. Finally, a mighty troll army charged out from the shadowy forests and once again laid siege to the shining spires of Quel'Thalas.
