Brassheart - The Cog Unwound - An Aventhral Adventure - D&D 5e Compatible

In a world powered by steam and sorcery, fortunes are forged in the soot-stained skies and secrets are buried deep within the grinding gears of progress.

Brassheart - A Steampunk World

The continent of Brassheart is a land of stark contrasts, where sprawling, soot-blackened cities of iron and brass are carved into jagged mountain ranges and verdant river valleys. Above, the skies are crisscrossed by the contrails of countless airships, from lumbering merchant galleons held aloft by humming aether-crystals to swift, hawk-like corsairs that prey on the unwary. The very air thrums with the hum of machinery and the scent of coal smoke, a constant reminder of the relentless march of industry. Great clockwork towers chime the hours, their intricate mechanisms powered by captured elemental spirits bound in arcane matrices, their light casting long, dancing shadows over the gaslit streets below.

The Wilderness

Beyond the reach of the cities, the wilderness is a place of untamed beauty and savage danger. The Churning Wastes are a vast, unstable landscape of shifting earth and geysers that spew scalding steam, home to metallic-shelled behemoths that feed on raw magical energy. To the south lie the Glass-Shard Jungles, where crystalline flora hums with latent power and territorial automatons, relics of a forgotten age, still patrol their crumbling domains. Magical anomalies are common; rivers might flow with liquid lightning for a week, or entire forests could become temporarily sentient, their whispers carried on the wind, luring travellers from the path. The weather itself is unpredictable, with sudden, violent aether-storms capable of tearing an airship from the sky.

Cogsworth

The heart of Brassheart is the metropolis of Cogsworth, a multi-layered city built around the colossal, dormant form of a god-like machine known only as the Great Cog. Its districts are a maze of wrought-iron bridges, pneumatic transport tubes, and towering manufactories that belch plumes of alchemical smog. Here, the promise of wealth draws inventors, artificers, and rogues from every corner of the land. Yet, beneath the veneer of progress, the city groans under its own weight. The lower levels, known as the Undercogs, are a labyrinth of rusted pipes and forgotten tunnels, where strange, gear-driven creatures hunt in the darkness and the dispossessed struggle for survival amidst the constant, deafening noise of the city above.

Step into the age of steam and sorcery, and let your players forge their legends in the shadow of the Great Cog.
