From Introduction:
Wilderness Encounters, Inner City, not only gives the GM fifteen assorted adventure seeds, complete with background information, NPC details and scenario options (should the players delve deep), but also a complete and instant city key, easily adapted to one of the blank maps included at the end of this file.
In short: Inner City is everything you need to run a unique, challenging and entertaining city adventure in the game setting of your choice. To start right now, go to the Instant City chapter and read on.
No stats are provided in this file, and no one ruleset is favoured. This is a generic module, designed to save the GM endless pre-session preparation without specific reference to any preexisting game system. For this reason we recommend you keep your game monster manual and any other core-rulebooks handy as the adventure unfolds.
