The Tyrants open paths between worlds to invade the other side. The Riders follow those paths to stop the invasion. You are one of them — and your Shard is already pulling.
Worlds that need help
The order of Riders brings together people from many layers. Every world that joined remembers when a Tyrant arrived. Its Riders travel on to give others the same chance they had: close the invaders’ passage and let life carry on.
The order has one simple rule: an open Rift is a Rift to seal.
Worlds like folded paper
The worlds lie in layers, like folded paper. Together, they are the Fold. Where it lies flat, the worlds live apart; many do not even know about the others. At the creases, two layers press together.
Time runs at different speeds in each layer. Some have had time to build machines; others hold primeval forests. Each has its own creatures and its own history.
No one knows who folded the worlds. No one knows if anyone did.
Amber remembers
Friction between layers leaves a residue in the creases that hardens into golden veins: Amber. Each fragment remembers the two worlds that formed it, like a fossil with two sides at once.
An undisturbed vein only glows. But the Unfolded learned to gather enough Amber into nests and link its memories. Heating the gathered Amber helps awaken it; a single fragment is not enough. The two worlds remembered by the nest touch, and a Rift opens.
The longer that link stays active, the wider the Rift grows.
Those who open want to rule
The Unfolded use Rifts to conquer other worlds. Some of the earliest Amber explorers were fleeing defeat or exile. Those who became Tyrants chose to turn their escape into conquest. Travelling between layers does not make someone one of the Unfolded; taking over other worlds is this faction’s choice.
Each Tyrant sustains a main nest. Their followers occupy the paths and maintain smaller nests to bring in troops. The Riders fight through these groups to reach the leader of the invasion.
Defeating a nest’s defenders lets a Rider break its link. The fragments lose their active glow, the nest cracks and the passage begins to close. At the main nest, the Tyrant and the remaining invaders must fall.
Those who seal ride the pull
Every Rider carries a Shard: a single fragment of Amber prepared by the order. Chipped, polished and with its memory stabilised, it glows cyan. It cannot open Rifts, even when heated. It follows paths that already exist.
When a Rift closes, the movement travels along the creases. The Shard pulls its Rider along that last path to the next crease that is giving way. The crossing finishes closing the passage behind them.
That is why they are Riders: they ride the pull. The Fold sets the destination; the courage to go is theirs.
Protect the Fold. Seal the Rifts.
Those who seal, carve
The order has a custom older than any written rule. When a Rift closes, the Rider carves the order’s symbol into the nearest stone: a shield with two folded layers and a crystal between them, painted the cyan of the Shard. It is the Seal. Every Rider adds a notch of their own.
To the order, the drawing is two worlds and the Shard between them: a person standing in the middle so that both stay whole. To the people who live there, it is good news: there was an invasion here, and it is over.
The worlds that were helped remake the Seal with what they have. A creased leaf with a drop in the middle. A spring with a rivet. Stacked slabs of basalt with one blue stone. None of them can say who taught them.
Seals that are too old
Riders find Seals in worlds the order does not remember visiting. Worn by centuries of rain, the paint long gone, with notches nobody recognises.
The order has no official answer, and the Riders freely disagree. Maybe there were others before. Maybe the order is far older than it thinks. Maybe it is only time: in a layer where time runs fast, last year’s Seal is already a ruin.
Veterans tell newcomers the story of the Rider who found their own notch on a thousand-year-old stone. Nobody believes it. Almost nobody.
A door locked from the outside
The Unfolded read it all the other way round. They say Amber proves the worlds were once one: if every fragment remembers two worlds, they must have touched one day. The Fold would be a prison, and the crystal between the layers the staple that keeps the paper folded. “Unfolding is freedom,” they announce. And they intend to rule everything they free.
That is why the Tyrants have the Seals broken in the worlds they take. The vainest carve their own version on top, with their own face on it.
