In ancient days, Daniel Bishop wrote an adventure for Mystic Bull Games -- Tribe of Ogg and the Gift of Suss. It was intended to be a stretch goal to our very first crowdfunding effort -- that resulted in our very first book: In the Prison of the Squid Sorcerer. At the time, I didn't understand complexities of the DCC RPG license, and I got in some trouble for commissioning an adventure without pre-clearing it with Goodman Games (they were already working on Frozen in Time!). Lesson learned. Water under the bridge. It's all good now.
Anyway, I had both of those prehistoric adventures in my campaign, and merged them with
the old TSR adventure UK5: The Eye of the Serpent. When the characters got to Area 16 of that module, it was woefully underdeveloped. So, I wrote Steading of the Nergalites, a site-based adventure for that area, based on a couple of concepts in my campaign -- the rise of Nergal and the resurgance of Qo, the Twin-Headed Serpent of Destruction.
So, yeah... The Steading of the Nergalites. Three different formats for the same content below and the hexmap for our Neolithic campaign.
