Free TTRPG battlemap of the Trackless Fens Treetop Bridges

While travelling along the boardwalk in a swamp, you hear hoarse cries from a woman and some men, begging for help. Catching sight of them you see four people tied against a large tree with rope as thick as your fist. Their lower halves are submerged in the water, their clothes torn and caked in mud. Smaller ropes tying their wrists dappled in blood.

When they see you they beg you to help them. They woke up here after passing through a village and eating dinner at the tavern, their possessions gone. They have no idea where they are or why, but urge you to hurry as they’ve been awake for hours.

By the time you make it off the bridge and down to where they are a snake as thick as a man and longer than the group combined emerges from the swampy undergrowth. Its tongue flickers out of its mouth as if it can already taste its next meal.

WHAT’S HAPPENING? Once every year a nearby village drugs passers through, before tying them up unconscious as a sacrifice to the gigantic snake. They’ve been doing this ever since they realised how, if the snake overeats, it sleeps for the rest of the year.

Originally the villager’s own small population was the animal’s prey. Their children would disappear from the village, or travellers through the swamp would never return. Since they started their annual sacrifices, though terrible, far less people die.

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.
