From publisher blurb: Torth is a strange desert world. Always night, always deadly. A little bit sword & sorcery, a little bit science-fantasy, and just enough post apocalypse to keep things interesting. Revelry in Torth is my 3rd adventure. It's got both wilderness and urban encounters. Just like Liberation of the Demon Slayer and The Islands of Purple-Haunted Putrescence, it contains a few house rules and campaign setting material. A couple new character classes are included, as well as, a few spells and magic items. This is geared towards novice adventurers. It's also O5R. To me, that means it's compatible with both the original fantasy roleplaying game circa 1974 and the most recent edition. I hope you enjoy it!
