A strange rot has infested the local farms, destroying vegetable produce and injuring those living who breath its spores. It was first noticed one month ago, when local hunters reported strange, small brown mushrooms with bio-luminescence and roots like veins. They appeared to be growing out of the entrances of caverns, leading to vast networks which run beneath the entire region…

Since then the rot has spewed fourth, contaminating the farms and forests above. The locals have tried multiple methods of cleansing it, but the infestation resists; threatening starvation.

You’ve been tasked to venture into the vast network of caverns to find its source, and perhaps, a solution.

What’s happening? Known for their amazing selection of exotic fungus, mountain dwarves export their mushrooms to the kingdoms of man. When a strange rot took hold within their growth tunnels, everything changed.

They tried everything they could think of to purge the rot, but none succeeded and the growth continued to spread throughout the underground network. Realizing that their efforts to contain the deadly infestation had failed, they sealed the contaminated tunnels so their city could survive.

Unknown to them, the mass continued to grow beneath their city, and sought other outlets.

The heart of this plague is a being who embodies living rot. Dark and twisting veins tie together carcasses of the dead, spreading spores and nutrients for its parasitic growths. Smaller creatures have broken off from it, wandering the tunnels and waiting for other living beings to incorporate into their own, rotting forms.

If one were to destroy the original, largest entity, perhaps the network of fungi would, too, fade…

LUKE: The founder of Seafoot Games, Luke's been making maps and RPG games since he was a child, and spent over a decade creating his own game systems from scratch to play with his brothers. That was before he discovered other TTRPGs existed. Now, he paints the realistic grimdark fantasy battlemaps we're known for, helps write adventures as needed, and spends his free time printing and painting 3D minis, as well as working on his forever in-development TTRPG system.

BEB: Luke's wife, Beb's been writing, painting, and graphically designing things her whole life. She published her first book when she was 20, alongside a handful of sci-fi short stories, and was responsible for writing almost all of our adventures until mid 2022 when Steve joined the team. Now she mostly creates the outlines for the adventurer's guides with Luke, graphically designs documents, handles the bookkeeping (or as she likes to call it, bureaucrat wrangling), and manages the website—but she is slowly delegating these responsibilities, so she can focus on raising her and Luke's beautiful son.
