I write modules for the first edition of Pathfinder Roleplaying Game.
My first adventure, Following the Tracks, is set in the savannah and has a decision point that will change the adventure drastically depending on what the PCs choose to do.
My second adventure, Arcane Oracle, is a location-based adventure where the PCs can explore a wizard's tower, deal with the elementals that are flooding the basement, and/or discover the fate of the wizard who lived there.
