Ny'alotha, the Waking City

Ny'alotha, the Sleeping City, has awakened. Under N'Zoth's command, the armies of the Black Empire threaten to engulf the world and reshape it according to their master's vision. Only one hope remains: using the repaired titan forges to eradicate the Corruptor once and for all. But in order to target N'Zoth with the forges' power, the champions of Azeroth must venture deep into the horrific realm for one final confrontation against the Old God.
