Crystal Bats, also known as xahgniathanor, were created by the Skeksis during the Garthim War.[1] They carried spy crystals in their talons, which would send images of whatever they saw back to the Castle of the Crystal.[2] Crystal Bats worked in conjunction with the Garthim, tracking down Gelflings and alerting the former to their location. The original stock consisted of largely nocturnal specimens, but selective breeding produced bolder strains which left no corner of Thra unknown to the Skeksis.[1]

During the Age of Power, with the Skeksis gone, control of the Bats was taken by the Crystalline Eminence, who discovered a way to modify the images transmitted by them, showing Jen and Kira an illusion of Thra being prosperous under his corrupt leadership.[3]
