Ultramancer

An Ultramancer was a metal-cased humanoid species presumably originating from one of the seven planets of the Sun-Singers of Akhet. At least one member of this species attended the Festival of Offerings at the pyramid of the rings of Akhaten at least once. (TV: The Rings of Akhaten)

An Ultramancer was on display in Hedgewick's World of Wonders. (TV: Nightmare in Silver)
