Waterdeep

The Yawning Portal Inn, built on the ruins of Halaster Blackcloak's tower, serves as the primary entrance to the Undermountain. Renowned for its deep well that leads adventurers into the vast dungeon below, the inn is a bustling hub for adventurers, merchants, and thrill-seekers. Managed by the legendary Durnan, a former adventurer, the inn offers hearty meals, a variety of ales, and a warm atmosphere filled with tales of glory and danger. The interior features a spacious taproom adorned with trophies from Undermountain, wooden pillars, and a large fireplace, while the upper floors provide comfortable guest rooms for weary travelers.

The inn is a large, rambling structure made of mismatched fieldstone, with thick walls and a steep slate roof. The ground floor has no windows, but upper floors feature wooden shutters. A sign reading 'The Yawning Portal' hangs above the entrance, and the interior is dimly lit by chandeliers and candles, creating a cozy yet smoky atmosphere.
