From the introduction:
This adventure is set in the Warrens of the City-State of Tyr, amid the chaos immediately following Kalak's overthrow and demise. It is designed for three to five PCs of third to fifth level, at least two of whom should be rogues, preservers, priests, or psionicists. "Chaos Opportunities" can be (but need not be) used as a sequel to David Cook's excellent Freedom flip-book module. Background: During the construction of Kalak's infamous ziggurat, hundreds of slaves worked and lived under inhuman treatment and conditions. The strongest and cleverest slaves banded together in gangs for survival, usually robbing slaves weaker, slower, or with less allies than themselves. An earth cleric named Granj (an NPC from Freedom that I am taking the liberty of developing), headed a less notorious but eventually more powerful sort of band, where members pooled resources, skills, and influence for survival.
