Arc Synapse is a sentient entity composed of pure electrical energy, constantly shifting and pulsating with vibrant neon hues. It possesses the ability to manipulate electromagnetic fields, allowing it to influence the trajectory and behavior of disc golf discs. Its form is highly unstable, requiring a containment field to maintain its coherence. Arc Synapse is both a source of immense power and a potential hazard, embodying the dual nature of the Spark Savants' innovations.

Arc Synapse serves as both a muse and a cautionary tale for the Spark Savants. It inspires them to push the boundaries of disc golf technology while reminding them of the potential dangers of unchecked innovation. Its presence at the league events adds an element of unpredictability, as its influence can dramatically alter the outcome of matches.
