Elizabeth is the name given to the cargo-lifting crane aboard the Steamer by the mechanic that maintains her. She was originally built by The Inventor in Parm and is often taken back to him for repair work. The crane itself is mounted near the front of the ship and has three arms used to load cargo onto the ship from port.
Story
Justin can talk to the mechanic aboard the steamer and he mentions how the inventor seems to have tampered with Elizabeth during his last repair job making her erratic and unstable (much like the Inventor himself). The sailor comments he has been working hard to "recreate her beautiful and smooth movements".
The party later uses Elizabeth as a bridge to cross over to the Ghost Ship.
