The Cauthrians were a mixed race of elves and humans, who became extinct during the Great Purge because they had magic in their blood. It is believed that they are descendents of the Veninar, and later the Druinar. They were from a region of Greater Galwyndor called Cauthria, which was a series of Southern islands called the Wyrmback Isles. It is said that the great warlock Gethalyn was of this race.
Skills
They were known predominantly for their seafaring, much like their rumored Veninor forebears. 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.
They were also recognized for skill of craftsmanship, especially engineering and weaponry. This is likely due to valuing curiosity, learning, and experimentation as a culture. These traits, combined with a love of travel, put them in a prime position to learn from a variety of cultures.
