The Forgotten Caverns are a network of natural caverns below the Deep Roads.
These caverns were previously connected to the lyrium mine beneath Heidrun Thaig but have been abandoned and seen no visitors since the First Blight. At various points, deep chasms are cutting through the caverns but they are traversable by using ancient dwarven stone bridges.
At an unspecified time after the First Blight the Sha-Brytol started inhabiting the Caverns. The Inquisitor may visit the location as part of The Descent (quest) in 9:41 Dragon along with Lieutenant Renn of the Legion of the Dead and Shaper Valta in order to find the source of the earthquakes.
