Revelry in Torth

Revelry in Torth


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...   [click here for more]

A Green Jewel They Must Possess

A Green Jewel They Must Possess


This short investigative horror scenario takes its name from the early 80s animated film Heavy Metal.  It's an homage to H.P. Lovecraft as is my own investigative horror RPG The Outer Presence. A green glowing sphere has been found in what was Sumeria.  It's both extremely powerful and dangerous.  The investigators have a chance to claim it before others can get...   [click here for more]

Don't let the other guy have all the fun!  It's your game, too.  Roleplaying is a contact sport, so get in there and make it happen!!!

Obsidian Escalation

Obsidian Escalation


As I did with Crimson Escalation about a year ago, I'm now making Obsidian Escalation free for every DTRPG customer, as I believe it's an important evolution in the O5R design school that seeks to elevate story and player-agency within that "storygame" sphere... without the expectant storygame garbage that usually comes with it.

Totally Random Tables

Totally Random Tables


A couple years ago, I started coming out with these completely random d6 tables on my Draconic Magazine website/blog. They were fun to do and, because they were only 6 results deep per table, I could come up with wild, funny, thought-provoking, or stupid-on-purpose entries every month or so. Once I had 30 of them collected, I decided that was a good point to self-publish what I had, sharing my gonzo...   [click here for more]
