Well of Eternity

Ten-thousand years in the past, the night elven capital city of Zin-Azshari was a magnificent, sparkling metropolis. Situated on the shores of the Well of Eternity, it was here that the aristocratic Highborne first opened a portal into the Twisting Nether and invited the Burning Legion to invade Azeroth. Under the command of the night elven queen, Azshara, they now pour their energies into the portal, preparing it for the terrifying and glorious entrance of the demon god Sargeras.
