Mirt's Mansion

On the opposite end of the mountain, close to the Naval Harbor, stands Mirt’s Mansion. Once a fortress-like and glowering tower, it has been upgraded with more delicate fashions of architecture since the return of its long-absent owner.

Mirt has quite a history with Durnan, the proprietor of the Yawning Portal. Together they descended into “the Well,” as the entrance to Undermountain was known in olden days. Waterdeep used to throw criminals in the Well, leaving them to die horribly in Undermountain’s dungeons. Durnan and Mirt entered the dungeons of their own free will — and not only that, but returned laden with treasures. Both used magic to extend their lives, but they eventually parted ways. Mirt kept on with a life of adventure, while Durnan built the tavern called the Yawning Portal over the Well and now, almost two centuries later, charges coin to descend into it.
