The night elves developed along the shores of the Well of Eternity, and so they were strengthened by its energies. Despite the trolls’ attempts to keep this new race from claiming further territories, the night elves built up a mighty empire that expanded rapidly across Kalimdor. Wielding fierce magics never before imagined by the trolls, the night elves soon threatened the two greatest empires on Azeroth, the Amani and Gurubashi Empires.
The night elves systematically dismantled the troll’s defenses and supply chains. Unable to counter the elves’ destructive magics, the trolls buckled under the onslaught. The territories of the Gurubashi and Amani empires fragmented within only a few years, and the night elves' shockingly quick victory incurred the trolls' eternal hatred.
