After years without any new campaign settings in (A)D&D, with everyone playing in Greyhawk and the unnamed (later Mystara) world of D&D, campaign settings are coming out pretty frequently with the last couple of years seeing games set in Ravenloft, Hyboria, Dragonlance, Pelinore, Kara-Tur and now Lankhmar. 

Originally the setting for Fritz Leiber’s Fafhrd and the Grey Mouser stories, this world was a huge influence on Gygax and his imagining of Greyhawk (you only have to read Gygax’s Gord the Rogue novels to see how influential it was), so it was only natural that the game would eventually incorporate the universe of Lankhmar into itself. 

With the prefix CA, standing for City of Adventure, this module is composed of three short adventures, each by a different writer, and a good selection of writers at that. A pretty good introduction to the world of Lankhmar with a seamless introduction of game mechanics into that world, this is a fun module with some great interior illustrations by Valerie Valusek.
