Rainbow Bridge Machine

The Rainbow Bridge Machine is a quasi-magical machine in Final Fantasy Mystic Quest. Created by Otto and stationed in Windia, the machine can be used to create the Rainbow Bridge, a bridge to Pazuzu's Tower. However, when strong winds from Mt. Gale damaged the machine, the Rainbow Bridge vanished. Once the winds had calmed, Otto repaired the machine and recreated the bridge, allowing Benjamin and Kaeli to enter Pazuzu's Tower.

Otto later powered up the machine with a Thunder Rock from Fireburg, allowing the Rainbow Bridge to extend further and reach the tunnel Spencer was digging under Aquaria.
