Leo and Maya, two new protagonists, discover a warm, magnetically charged glass ornament in a dormant greenhouse attic that bears markings similar to the Key Stones. They realize the ornament is reacting to the growing magnetic hum affecting the town. Their journey leads them to the back alley of The Rolling Pin Bakery, where they catch Finn trying to access the reserve sugar crystals (from the silo) to guarantee the Luck Loaf's sparkle. A powerful, deep magnetic hum resonates through the ground, causing Leo's ornament to vibrate violently. This forces Leo to convince Finn to abandon his immediate task and follow the resonance into the Whispering Woods, linking the ornament to the larger mechanical mystery.
