They are tall and willowy, with pale skin, silvery grey or golden eyes and long silky golden or white hair. They possess six fingers on their hands and are humanoid enough to reproduce with humans. They usually appear androgynous or sexless but are actually hermaphrodites, they change orientation depending on the need. When in their natural state it is known as emmasca, usually when they find a mate one must be male or female and this will cause a shifting of the other to be the opposite so mating and procreation can occur.
Laran also originates with the Chieri, they possess incredible psi-abilities which were passed down due to the interbreeding with humans. Chieri must be "in season" to mate with each other but due to pairs not being on the same cycle their numbers started to decline. A similar effect also plagues their human descended children where they do not feel the sexual urge for intercourse and reproduction strongly. Some of their human descendants can also be genetic "throw backs" and be born emmasca, usually very androgynous looking and usually sterile.
