The World

The Riverbound Sphere is a round world threaded by one vast network of navigable rivers, each current eventually joining the next beneath unfamiliar stars. Towns measure wealth by boats, bridges, and clean wells, while common magic makes every ferry crossing and harvest a small act of wizardry. Now the rivers are rising, old ruins are surfacing, and rival powers argue whether the flood is a warning, a weapon, or the world's attempt to correct an ancient mistake.

The Ages

  1. The Finding

    First Age

    The first settlers followed a silver river from the eastern sea and discovered that every major waterway crossed the whole globe, joining distant lands in one living circuit.

  2. The Shared Banks

    Middle Age

    River towns grew into leagues, roads became secondary, and common magic spread through ferrymen, healers, farmers, and soldiers who learned to draw power from flowing water.

  3. The High Water

    Current Age

    A strange rise has filled rivers beyond their old courses, exposing buried ruins while rival powers fight over dams, crossings, and the right to control the world's flow.

Secrets

The Riverbound Sphere itself is alive, and the current flood is its fever.

Discovery · Flooded carvings match symbols found on ferries, grave markers, and royal seals.

Impact · The rivers are not natural waters but the exposed veins of a sleeping world-sized creature.

Souls can no longer reach their final destination.

Discovery · Ghosts vanish when carried beyond the world's known coast, leaving behind wet footprints.

Impact · Death has begun failing because the unseen sea is being blocked by an ancient machine.

A vanished land still exists beneath the sea.

Discovery · The oldest maps show a fourth region where open ocean now lies.

Impact · Restoring the lost region could stabilize the rivers, but it would displace every modern settlement along the coast.
