Styx

The Styx is a prison barge, a type of ship that is used to transport prisoners from the mainland to an island prison in the world of Galfin. This barge is a regular barge ship, with a large, flat deck and a secure hold that can be used to transport large numbers of prisoners. The most notable feature of the Styx is that it is towed by two large whales.

The whales are specially trained to pull the Styx and are able to navigate through the roughest seas and currents. This method of transportation allows the ship to move quickly and efficiently, making it ideal for transporting prisoners over long distances. The ship has several guards onboard to watch over the prisoners and keep them secure during the journey.
