Xararian

Xarar and its colony worlds in The Vast have been ruled for millennia by an elite hierarchy of powerful spellcasters. Those who show a talent for magic and embrace these values are collected from their homes and dispatched to arcane colleges that tower over the largest cities of Xarar, while the rest of the population are doomed to a life of backbreaking servitude. Both organized religion and technology are suppressed, out of fears that divine empowerment or advanced machinery might lead to a bloody peasant uprising.
When Triune granted knowledge of The Drift to the people of Xarar, those in power on the planet saw it as the greatest of all possible threats, moving swiftly to destroy all record of its existence on their own world.
Relying on divination and teleportation magic, dedicated thaumaturges were dispatched far and wide to assess the growing threat of technology from the greater universe. The majority of these agents are xararians, humanoids with wrinkled brows, long white hair, and pale skin. Rarely, other races under Xararian subjugation are also appointed as thaumaturges; after decades of study, they are finally allowed to don the traditional black flowing robes and elaborately carved staves that mark their high station.
