Dwellers of the Forbidden City

Dwellers of the Forbidden City is an adventure module for the fantasy role-playing game Dungeons & Dragons, set in the game's World of Greyhawk campaign setting. It was published in 1981 by TSR, Inc. for the first edition Advanced Dungeons & Dragons rules.

The adventure was written by David Cook with cover art by Erol Otus and interior art by James Holloway, Jim Roslof, Harry Quinn and Stephen D. Sullivan. It was first used as a tournament module at the Origins International Game Expo in 1980.

The module was originally intended to bear code S4, but this code was re-assigned to Lost Caverns of Tsojcanth before Dwellers was published. As published, the adventure bears the code I1 and is the first in the I (Intermediate) series of modules, a group of mostly unrelated adventures.
