Thumper

A device of unknown origin or purpose, found on the body of a Shadow Cultist. Manley suspects it can be networked with identical devices to either manipulate the orbit of islands in the Island Ring or to call beasts to the surface of the World Crust - maybe even the World-Eater. He, Chroma, and Mavia attempt to take it to Avania for further investigation, but instead find their airship sabotaged and crash on the island Bajeisa. The Thumper has been stolen.
