Naz'anak: The Forgotten Depths



Naz'anak: The Forgotten Depths is a cave located far beneath Icecrown Citadel. It is divided into two small rooms, each with a small lake at their center. They are connected by a nerubian hallway that contains the Altar of the Ebon Depths. Naz'anak has a rich biodiversity of fungal plantlife, and also has faceless ones. Matthias Lehner could also be found here.

Adventurers explored the cavern but the explosion of several saronite bombs knocked them off the rail, and into a large saronite-lined hole, falling down through a crack in the ice into the water.

Speculation
Given the presence of n'raqi and nerubian architecture, it is speculated that Naz'anak could be the Icecrown exit of the Azjol-Nerub tunnel that Arthas and Anub'arak used in the mission Ascent to the Upper Kingdom.
