The Ocean Semphesteus separates Drentae from Hughijen. Named for an ancient Tandish god, it is most often referred to simply as Semphesteus. It is the most traveled ocean in the world, carrying traders back and forth between the two closest continents.
Helatia is the main trading port on the west side of Semphesteus, while Purity is the main port on the east. South of Semphesteus the sea becomes the Anglic Straits. Cartographers disagree as to whether the Anglic Straits are part of or simply next to the Ocean Semphesteus.
