The Wailing Ziggurat is a Scourge ziggurat located south of the Temple City of En'kilah. Thassarian, as leader of "Unit S"[citation needed], led an attack to claim this ziggurat and now uses it as a base to find a way into the necropolis of Naxxanar — where he believes the hidden infiltration of Valiance Keep by the Cult of the Damned is based.
