The Cauthrians were a mixed race of elves and humans, who became extinct during the Great Purge because they had magic in their blood. They were from a region of Greater Galwyndor called Cauthria. It is said that the great warlock Gethalyn was of this race.
They were known for their seafaring and skill of craftsmanship, especially engineering and weaponry. As consummate navigators, they were believed to have discovered many uninhabited islands and remote locations throughout the world. Many of the best maps of the ancient world were of Cauthrian make.
