The setting
When the Bleed opened, twenty-one worlds touched a palace outside time. Essence — the force behind courage, invention, motion, and trust — now flows as four currents. You play the champions who walk them.

Essara, the Essence Mistress, cannot enter a living universe without tearing it apart. She sends visions, opens doors, and trusts mortals with the rest.
A campaign in the Nexus is a crossing: a rescue through a drowned ocean, a briefing on a near-future Earth, a vow sworn in a city of borrowed faces. Your Origin is the world that made you. Your Essence is the current you carry.
“Sheena gives us the strength to endure. Stella gives us the speed to answer. Samara gives us the wisdom to understand. Solica gives us a reason to stand together.”
