Orpheus is the name of a ship. Judging by its design and name, it appears to be of Tiefling make.

It was carrying exiles and criminals from the mainland to a remote island, when storms drove it into the rocks of said island. The prisoners took the chance, and fought their way to freedom. Later on, Dorrel, Orethel, Oruruk, Rathgul and Taliesin helped Rooark and his group to fix the ship, using makeshift tools, magic, and the remains of another wrecked ship.

During the sea journey out of that island and due to a fight that occured on board, the ship's hull broke with too little time to fix it.

The ship eventually sank to the bottom of the Oblivion Sea.
