The Shadow Web Caverns are an area in Azjol-Nerub. Arthas Menethil crossed this cave to reach the Old Kingdom and later Icecrown Glacier. He fought a group of dwarves led by Baelgun Flamebeard and some still-living nerubians led by Queen Nezar'Azret.
The caverns have some hidden passages crafted by the nerubians during their time. It also houses a nerubian hoarding cell, which are chambers where they used to keep most of their treasures hidden.
Presumably, the caverns are between the entrance of the nerubian home (which may or may not be The Gilded Gate) and the Old Kingdom Gate.
- Baelgun's camp is the same Doorward location from the RPG.
