Dwellers of the Forbidden City is an adventure module, or pre-packaged adventure booklet, ready for use by Dungeon Masters in the Dungeons & Dragons (D&D) fantasy role-playing game. The adventure was first used as a module for tournament play at the 1980 Origins Game Fair, and was later published by TSR in 1981 for use with the first edition Advanced Dungeons & Dragons rules. The module was written by game designer David "Zeb" Cook, who partly ascribes his hiring by TSR to his work on this module. In the adventure, the characters are hired to find an object taken to a lost oriental-style city, which has been taken over by a cult of snake-worshipers, the yuan-ti, and their servants, the mongrelmen and tasloi. The module was ranked as the 13th greatest Dungeons & Dragons adventure of all time by Dungeon magazine for the 30th anniversary of the Dungeons & Dragons game in 2004. Plot summary The adventure begins when the player characters hear reports of bandits waylaying and attacking caravans in a jungle region. Most of the ambushed merchants and guards have been killed, but the few who have returned alive tell fantastic stories about deformed plants and deadly beasts in the jungle. The stolen goods taken from the caravans provide an impetus for the characters to enter the jungles in search of this lost treasure. After a long and perilous journey, the player characters encounter some friendly native people and are invited to stay in their village. The characters learn from the village's chief about the dangers of creatures called the yuan-ti and their servants, the tasloi, and that these creatures recently kidnapped the chief's son, taking him into the jungle. The chief and village shaman tell the player characters about a "forbidden city" in the jungle which they believe houses the ghosts of their dead enemies, and they supply the characters with guides to show the party the way to this forbidden city. The adventuring environment in this module allows for both action and intrigue. The player characters can recruit allies from the various power groups and factions within the city, namely the bugbears, mongrelmen, and bullywugs, or else help pit these factions against each other for their own benefit.
