About the adventure

Volothamp Geddarm sets the adventurers off on an urban-themed treasure hunt for a massive hoard of gold within the city of Waterdeep. Undermountain is the lair of the insane wizard Halaster Blackcloak who descended into madness as he dug deeper under the city of Waterdeep and expanded his domain. Many creatures overpowered by Blackcloak are contained in different levels of his lair along with multiple portals to other parts of the Forgotten Realms and the multiverse. Adventurers set off on a subterranean dungeon crawl that starts in the Yawning Portal tavern and explores twenty-three levels of Undermountain and the refuge of Skullport (which is both a connection to the seedier side of Waterdeep and to the Underdark).
