Dead God Excavation

Dead God Excavation


"This thing is pretty f#cking Lovecraftian!" ~ Abdul Alhazred Dead God Excavation is a short adventure for characters between 1st and 3rd level.  I happen to think it's perfect for kicking off a gonzo, eldritch, science-fantasy campaign.  If you incorporate this into your "session zero"... respect, hoss! This scenario was written for Crimson Dragon Slayer...   [click here for more]

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. Also, now's the time to grab your weekend...   [click here for more]

Battle For The Purple Islands


This is pure gonzo-light, science-fantasy, eldritch pulp awesomeness!  O5R compatible (including Crimson Dragon Slayer) scenario pretty much requiring The Islands of Purple-Haunted Putrescence (if you don't already own it, get it - you'll thank me).

Loathsome Secrets In Amethyst

Loathsome Secrets In Amethyst


This is the latest in a long line of Cha'alt scenarios.  Unlike the vast majority, this one is for higher level (4th and 5th) PCs, but like anything, it can easily be adjusted on-the-fly. I used Midjourney A.I. to create almost every piece of artwork in this PDF. At the end of Loathsome Secrets In Amethyst, you get a massive d100 table for infernalizing an item...   [click here for more]
