What is Quel'Thalas
After the destruction of the Well of Eternity thousands of years ago, the High Elves left Kalimdor behind them and challenged the storms of the Maelstrom. Once their fleet finally landed on the beaches of the kingdom men would later call Lordaeron. After many long years, the high elves finally found a land which was reminiscent of Kalimdor.
Deep within the northern forests of the continent, they founded the kingdom of Quel'Thalas and vowed to create a mighty empire which would dwarf that of their Kaldorei cousins. Unfortunately, they soon learned that Quel'Thalas was founded upon an ancient troll city that the trolls still held to be sacred. Almost immediately, the trolls began to attack the elven settlements en masse.
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. 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.
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.
