The Castithan (Second Human Empire: Hamo Yuin'uiki Vuui'looi) are one of the member races of the Votan. They originate from the planet Daribo but had a significant presence on the planet Casti. The Castithan appear very similar to humans. Their coloration is very pale, however, verging on albinism, with pale white skin, white hair, and pale yellow eyes. The Castithan society is aristocratic and hierarchical, and the other Votan races view them as arrogant. The Castithans used to have a patriarchal, rigidly segregated society on their home planet based on castes (known as liros), though this has broken down somewhat among the survivors on Devi'uikni Earth due to the harsh conditions of the war and its aftermath.
