Precursors: Origins of Folklore

The Precursors Wiki

An archive of what came before — and what might yet be.

About This Archive

The world of Urd Prime, documented.

This wiki documents the world of Urd Prime — the six biomes, sixteen species, seven fallen civilizations, and the intelligence system that shapes everything. It is compiled from Shee field notes, Ettin archaeological records, Raven observation logs, and things that should not have been remembered but were.

The Shee designed this world. But the Shee who designed it are not the first Shee. The civilizations that failed before left more than ruins. They left chemistry, instincts, and questions encoded in the bodies of every creature alive today.

Seven tried. You are the eighth.

World Guide

Urd Prime: six biomes, four vertical tiers, the Norse etymologies behind every name, and the Ancient Ark beneath it all.

🧬

Species

All sixteen species with full genome ranges, biochemical signatures, secret histories, and the folklore traditions that named them.

Civilizations

The seven fallen civilizations and the Ur-Shee Pantheon — the deities who remember what every living creature has forgotten.

🧠

Cognitive Tiers

The six tiers of intelligence, the thirteen hidden lore events, visiting species from across world mythology, and the Ancient Ark's decks.

🧪

Biochemistry

All 48 chemicals — energy, drives, hormones, nutrients, damage, reproduction, neurotransmitters, meta. How organs, reactions, receptors, and emitters run every living thing.

⚙️

Gameplay

Breeding, carrying, the item system, machines aboard the Ancient Ark, multi-planet transit, and life stages — everything The Hand needs to know.

Lore Events

Thirteen moments that cannot be undone. The First Question. The Recursion. The Awakening. Each fires once, permanently, and only when its conditions are met.

Species Deep Dives
⚠ Note: Some pages contain spoilers for late-game discoveries. The sixth cognitive tier is real. It is not described in any Shee records. We do not know what it leads to.

What you're walking into.

7 Fallen Civilizations

Before the Norns

Each failed for a different reason. Each left something behind in the bodies, chemistry, or terrain of the creatures who came after.

🧬

16 Core Species

Plus 35+ Visitors

From Norns to Jotnar. Every species has a distinct genome, biochemical profile, cognitive ceiling, and secret history.

🌏

6 Biomes

One Hidden

Fungal Grotto, Verdant Shelf, Crystal Caves, The Threshold, The Deeps — and one biome not in any official Shee survey.

6 Cognitive Tiers

Tier 6: Unknown

Five tiers are documented. The sixth requires The Recursion event and is the only state from which the substrate can be directly perceived.

The Ancient Ark

Beneath Everything

Six decks. A resonance amplifier. Genetic archives. A cargo hold. And something sealed in brass that has been waiting longer than the Norns have existed.

📜

13 Hidden Events

Lore Triggers

The First Question. The Grief. The Recursion. The Awakening. Each one changes the world permanently when it fires.
