Quartet is a 20-30 hour single‑player RPG that weaves together four separate, self-contained stories into a single epic. Start any of the four campaigns in any order; as they converge you’ll assemble a final cast of eight heroes who will uncover a secret, centuries‑old conflict and face a choice about the destiny of magic. Along the way the plot touches on train robberies and a government conspiracy, a mysterious deck of cards that reveals another world, deadly airships cutting across an imperial frontier, and an unlikely hero whose sudden power reshapes everything.
