The Photon Cascade is a self-sustaining energy phenomenon that exists as a flowing stream of concentrated light particles. It emits a faint hum and a soft, pulsating glow, with the ability to interact with specially designed discs to enhance their flight dynamics. The cascade is highly unstable but can be controlled using advanced magnetic fields.

The Photon Cascade serves as the Spark Savants' primary energy source for their most advanced disc technologies. It powers experimental discs that can manipulate light and energy mid-flight, giving players unprecedented control and precision on the course.
