One Star, Fourteen Shards
After the Sundering, the Source remains the primary world; the thirteen reflections drift in parallel, each with its own history and calamities.
Rejoinings
When a reflection is reabsorbed, the Source grows stronger and the Ascians move closer to their goal of restoring the ancient world.
Narrative Role
The structure allows for alternate worlds like the First while keeping the story centered on the Warrior of Light.
