Clockwork Isle Caper

You, Pip Marcello, freelance relic-runner, have just paddled ashore on the Isle of Gears — a forgotten outcrop packed with rusted clockwork automatons, all frozen mid-task. Your prize: the Solarian Lens, a fist-sized disc of polished gold locked inside the Master Clocktower's inner vault. Trouble is, your rival Duchess Varla arrived first and is lounging against the tower door, convinced she has the only key. The vault's lock isn't a keyhole, though — it's a light puzzle, and Varla doesn't know that yet. You do. Barely.
