Chapter One: A Friend in Need

The adventure kicks off in the legendary Yawning Portal tavern, where a sudden troll attack interrupts the adventurers' evening. Soon after the chaos settles, they are approached by Volothamp Geddarm, who tasks them with finding his missing friend, Floon Blagmaar. The search leads the party into the seedier parts of the Harbor District, following a dangerous trail of blood and gang violence.

Their investigation brings them to a Zhentarim warehouse on Candle Lane, the scene of a recent, bloody skirmish between rival criminal factions. After dealing with the remaining thugs and discovering a hidden stash, the clues point downward into the dark, labyrinthine sewers of the city.

Descending into the muck, the heroes must navigate dangerous tunnels marked by the Xanathar Guild. They eventually infiltrate a subterranean thieves' hideout, braving guard posts, a grim interrogation room, and foul latrines to rescue Floon from the clutches of a cruel underground syndicate.
