Nazjatar, the great capital city of the naga, is built into the walls of the Rift, by the ruins of Suramar. It is where most naga dwell and their queen, Azshara, holds court within a beauteous palace even larger than her former home on land.
Somehow, against all odds, Queen Azshara and her Highborne elite managed to survive the ordeal. Tortured and twisted by the powers they had released, Azshara and her followers were dragged down beneath the raging sea by the Well's implosion. Cursed - transformed - they took on new shapes and became the hateful serpentine naga. Azshara herself expanded with hate and rage, becoming a massive monstrosity, reflecting the wickedness and malice that had always hidden within her core.
There, at the bottom of the Maelstrom, the naga built for themselves a new city, Nazjatar, from which they would rebuild their power. It would take over ten thousand years before the naga would reveal their existence to the surface world.
