The Sapphire Song is an Ordennan warship used to flex the island's military might.
During the Autumn in Hieron holiday special, it was docked in the Velas harbor and captained by Stornras Glasseye. It later appeared during the investigation of Gilbert Lutz's possible death in Rosemerrow, at which time Impetor Fela Malle had stationed it outside Creek Crescent.
