Undermountain

Older than the city of Waterdeep itself, Undermountain is a massive dungeon that descends deep under the city to depths that few can fathom. Constructed by the mad mage Halaster Blackcloak, it is rumored to be filled with traps, monsters and cursed magic most foul from across the multiverse. The only known entrance to the Undermountain is within the The Yawning Portal.
