This is a weird, science fantasy, gonzo campaign setting and wilderness hex-crawl for old school fantasy roleplaying games. The Islands of Purple-Haunted Putrescence is a guide for helping you run crazy sandbox scenarios in a lost world of Snake-Men, dinosaurs, and mutant sorcerers... an exotic and deadly region possessed by a demonic, purple-hued god of ruin and consumption. If you're into the OSR or just want some strange 5e flavoring, give this a try. It's not your usual adventuring environment, but it will be memorable! The Islands of Purple-Haunted Putrescence was successfully funded via Kickstarter at the beginning of 2014 and is the follow-up to Liberation of the Demon Slayer.
