I1: Dwellers of the Forbidden City, is an adventure module for 6-8 characters of level 4th to 7th.

This adventure is set in the mountains south of the Pelisso Swamp in Hepmonaland(p.2). The Forbidden city, later named Xuxuleito was expanded in 2e AD&D Scarlet Brotherhood, as a city in the Xaro mountains, that once was ruled by batmen and olman, then later yuan-ti[1](p.56).

Dwellers of the Forbidden City was used at the 1980 Origins AD&D tournament(p.2).

The module was originally earmarked for the S4 (Special) code[2](p.29), but this was then given to The Lost Caverns of Tsojcanth.

The module requires the Fiend Folio for the full description of many monster stats, but can be played without it(p.3)


"Somewhere in the heart of the steaming jungle lies the answer to the whispered tales - rumors of a magnificent city and foul, horrid rituals! Here a brave party might find riches and wonders - or death! Is your party brave enough to face the terrors of the unknown and find - the Forbidden City!

Parts of this module were used in 1980 for a major East Coast convention tournament. Information is presented here to reconstruct this exciting tournament and even more has been given to expand play. Here characters may adventure several times in a unique and interesting mini-campaign. Included in this module are background and tournament notes, referee's keys, new monsters, pre-generated characters, and eight different maps."

David Zeb Cook was inspired by the Conan Novella, Red Nails, an tried to capture the feeling of the novella for this module[3]. Dweller's was originally part of a home campaign Cook ran before joining TSR, and he submitted a chapter as part of his resume. The adventure was later scheduled for a publish module, so Cook fleshed it out with the city and mongrelmen near the ruins[4].

White Dwarf, Jim Bambra, reviewed the module as a potentially good setting book for a DM to make their own adventure, but lacks cohesion as an adventure itself and is only given a 5/10[5](p.16).

James Wyatt, in the 4th edition DMG, suggests that Dwellers of the Forbidden City was the first or 'proto super adventure', havng a rich setting and nonlinear goal, along with suggestions for further adventures. Wyatt suggest that with more content and space to expand ideas, I2 could rival T1-4: Temple of Elemental Evil in terms of being a super adventure[6](p.148).

Different Worlds, Anders Swenson, reviewed the module as a 'Good Buy', and enjoyed the novel setting of the adventure, but does criticise the repetition of monster stats[7](p.39-40).

Dungeon ranked Dwellers of the forbidden city as the 13th greatest adventure, primarily for the monsters it introduced into the hobby[8] (p.76)

Ares magazine, Gerry Klug, gave the module a harsh review, criticising it's lay out and plot, calling it disorganised.It praises the new creatures, but not the ecology of the module, claiming such coexistence is implausible[9](p.31-32).
