The Mad Mage
In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of this crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers. Known as Undermountain, this dungeon is the domain of the mad wizard Halaster Blackcloak. Long has the Mad Mage dwelt in these forlorn depths, seeding his lair with monsters, traps, and mysteries—to what end is a constant source of speculation and concern. Treasures and secrets abound, but tread with care!

Fools and weaklings are the ones who find themselves setting out for Undermountain from the tavern. Those individuals who truly know what they are doing find other ways to infiltrate it. Ways that might lead through the Sea Caves and routes frequented only by those quick and daring enough and with the right crew to avoid detection on their way to their starting point. The Port of Shadows or Skullport as it is sometimes called is a hive of scum and villainy said to be run by Xanathar's thieves guild. But it is only a jumping off point for adventurers who wish to get deeper into Undermountain quicker.
