An ancient scroll speaks of a powerful weapon from the fabled Clockwork City, waiting deep within the mountains. It has lain abandoned for centuries after a catastrophe destroyed its dwarven creators.

Despite the lack of life within this place, the clocks and cogs of the city have continued to churn faithfully; hisses and ticks echoing throughout the cavernous ruins, bolstered by clouds of steam. Small mechanical creatures scuttle about, performing repairs on the city, as well as each other.

While adventurers have made it into some areas of the city, you find many of their bones lying covered in dust. When you finally enter the room deep within the city that has been left undisturbed since the calamity—the room containing the weapon—you trip it’s defense system. Suddenly hundreds of the little mechanical creatures swarm the floors, banding together in its center to create a gigantic clockwork dragon.

Once defeated, you trigger the seal suspending the weapon in a cage above the magma. As the chamber is lifted up, the weapon is revealed to be a young girl.

What’s happening? The ones who built this city succeeded at creating synthetic life. However, they did not know its cost. The girl is a homunculus, made in an experiment that unknowingly harvested the lives of the entire civilization.

By the time they realized the consequences of their spell, it was too late to stop. Seeking to create immortal life, they instead transferred all of their lifetimes into their creation, who has been held in stasis ever since.

She does not need food, or water. Wounds that would kill her heal as they use up one of the hundreds of lives she has left. Her creators were magical beings and when they created her, they transferred their power into her as well. She holds all their magical potential, broiling within her—but she doesn’t know how to control it. Not yet.

Highly impressionable and taken to flights of imagination, she can be molded into something good or evil.

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.
