The dungeons beneath Castle Ehb were the huge underground complex that lay beneath Castle Ehb. They served many a purpose; including a barracks for the 10th Legion, a storehouse of food in the case of a siege, and the housing of Ehb's dangerous prisoners. Also hidden within the deeper parts of the dungeon were such rooms and devices such as a horrific hall of torture, the secret Chamber of Stars, and if one had access to the correct ward-breaking spells, the Vault of Eternity in which Gom and the Seck were held for 300 years. During the Seck Resurgence, the dungeons were the site of one of the most intense battles to vanquish the Seck and make Ehb safe again.
