The Loom

World Overview

The world is one of extreme variety — species, biomes, and systems of power that change radically across time. In some eras, dozens of distinct magical systems coexist. In others, deep empirical science has replaced the supernatural entirely. The diversity is not arbitrary: it is the accumulated consequence of collapse.

Every catastrophe leaves residue. Every residue becomes terrain. The world's geography is a fossil record of its history — forests with fractal-impossible growth patterns were once near a catastrophe; deserts of crystallized glass were once cities; mountain ranges that form geometric spirals were not always mountain ranges.

The one constant across every civilization and every age is a particular shape of ambition: the desire to find a limitless source. Not conquest, not domination — something more innocent and more dangerous. The desire to remove scarcity from the equation entirely. This desire is civilizationally universal and cosmologically fatal.

Every civilization that reaches far enough eventually reaches for infinity. Infinity cannot be held. The reaching is the tragedy, and the tragedy is the world's history made physical.

The Physics of It

Reality in this world is, at a fundamental level, a finite system — not in the sense that resources run out, but in the sense that existence has edges. The laws of physics, magic, and logic are the shape of that container.

An infinite source — a perpetual motion machine, a limitless magical font, an engine that produces more than it consumes — does not generate more energy within the container. It punctures the container from the inside. It creates a point where the boundary between real and not-yet-real dissolves. What leaks through is not more energy. It is unreality: raw potential, things that don't follow rules because they come from a place where rules haven't been decided yet.

The warping this produces is called The Fraying. Crucially, the unreality that floods through doesn't simply dissipate. It cools. It calcifies into new and consistent rules — different from what existed before, but coherent within themselves. This is where new magical systems come from. Catastrophe is the world's primary mechanism of generating novelty.

Key Terminology

The Four Layers

The world's structure operates at four scales of recursion. Each layer looks identical in shape to the one below it, one order of magnitude larger. The mechanism that ends one layer is the same that begins the next — the cure is always the seed of the disease.

The Fraying — Proximity Gradient

The Fraying's effects follow a clear gradient based on proximity to the Apeiron and duration of exposure. This is the Teller's primary tonal dial.

Epoch Progression

The Power Epoch (Current)

The civilizational pursuit is limitless productive work — an engine that generates more than it consumes, a battery without depletion, a magical source without end. Different Cycles have different technical idioms: mechanical, computational, electrical, alchemical, arcane. The underlying desire is identical across all of them.

The Knowledge Epoch (Next)

The Knowledge Epoch begins the moment the Power Epoch ends — seeded by the very act of ending it. The civilizational pursuit: direct perception of base reality. Seeing the thing itself, without the mediating buffer of imperfect sense.

Why this is fatal: Reality as stable, navigable experience is a collaborative fiction between conscious minds and the physical world. The imperfection is load-bearing — it is the tolerance gap that lets the system flex without snapping. Removing it doesn't reveal a sharper truth. It reveals one that is uninhabitable.

The Proof Engine

Ending an Epoch — stopping the cycling itself — requires assembling the Proof Engine: a machine built from Relics recovered from across the Epoch's Cycles. Each Relic is a physical artifact from a specific Apeiron event — a different civilization's version of the same mistake.

Assembled correctly, the Relics constitute a complete logical argument demonstrating that infinite power as a sustainable state is self-contradicting within the rules of this universe. The machine doesn't force this truth. It presents reality with a proof it cannot refuse. A complete proof, submitted to the system it describes, becomes axiomatic.

The Relics are not fuel or components. They are testimony. Each one is a witness to a Cycle. The machine listens to them and structures what they say into a form reality can receive. Players aren't collecting MacGuffins. They're gathering the dead's evidence and making sure it counts for something.

The Tethered

The Tethered are the only institution with genuine cross-Cycle institutional memory, because they are the only people who believe the old stories are true. They exist in every era, looking different in each: government investigators, a paranormal research bureau, a religious order, a knightly guild, a desperate survival cell with forbidden knowledge.

What remains constant: they are always slightly outside the mainstream of their era's intellectual culture. Almost always underfunded, undermanned, operating in a context that considers their concerns either quaint or alarming. They are not a heroic order that wins. They are the people who understand what is happening and bear the weight of that understanding.

They call themselves the Tethered because their purpose is to tether reality — to hold the line between what is and what could unmake everything. They are also tethered to the memory of what came before, when everyone else has cut that cord.

Campaigns

Three primary campaigns form the narrative spine. They can be run sequentially or by different groups whose records pass between them. Mini-campaigns are self-contained stories, each producing a Relic.
