Old Shanatar

Extending for hundreds of miles beneath Amn, Tethyr, and Calimshan, Old Shanatar was once home to the powerful dwarven realm of Deep Shanatar. Only one of Deep Shanatar’s eight kingdoms still stands today; the others have fallen to drow, mind flayers, and duergar. Of the major domains, Old Shanatar contains the most artificial delvings, halls, and passages, including works of tremendous scale.

Old Shanatar, like the Northdark, has been reasonably well explored.
