Teppers have completely white eyes, with no iris or pupil. This does not impede their vision in any way due to their innate Mind Magic, and they otherwise look like typical humans. They cannot use any targeted Mind Magic without touching their subject.
Teppers are primarily concentrated in Port Fins, Hannaderres, on the world of Lezaria. Port Fins teppers have a culture requiring them to disguise their nature through using illusion to make their eyes appear normal, and to wear gloves to prevent accidental contact.
