What is this system

Not quite a system — more of a mega-module setting for any OSR game. A linear route through psychedelic wastelands — a 'pointcrawl' (traveling point to point along a route). Every week of travel brings a new wild location. Works with Cairn, Into the Odd, D&D 5e — adapts to any engine.

Setting

You lead a trade caravan from the Violet City through ultraviolet steppes to the Black City at the edge of the world. Along the way: cat-people on sailboats, living mountains, ruins of civilizations that toyed with reality. Style — Moebius + Yellow Submarine + Dying Earth.

What it looks like at the table
Week 7 of the journey. Caravan: two camels, a cat-folk mercenary, a wagon of violet crystals. You enter the Singing Waste — the air vibrates, the crystals start resonating. Luck roll — failure. One camel goes mad from the sound and bolts. Half the goods are lost. Ahead — the Glass Fair, where memories are traded.

Key mechanics

Art as content

Luka Rejec is an artist. Every page is a work of art. The style inspires play all by itself.

Caravan economy

Resources, trade, hirelings. The caravan is your mobile home. Managing it is core gameplay.

Linear route

The map is a path with points of interest. Every week — a new location. Simple structure, infinite depth.

System-agnostic

Works with any OSR system. Cairn, ItO, even 5e. UVG is content, not rules.

What people say

Ultraviolet Grasslands is a phenomenal RPG. My players had enormous fun with it, and I had enormous fun running it.— Tristan Zimmerman, Molten Sulfur Blog
