This is an intelligin, one of my other alien creatures. Their skintones can be pale blue, pale pink, or pale purple, but thats it. They don't tend to have any markings such as freckles or spots on their skin, but they do make a habit of chopping off extremities in order to make life "easier." If you have robot legs, your legs will never get tired, that sort of thing. Matter of fact custom cybernetics is the biggest industry in their culture, along with preforming arts and culinary related fields of course. Basically imagine a group of people drinking wine watching an opera while discussing robotics during intermission. That's them.
As for biologically speaking they have the interesting trait of having a split personality built into their biology. Their brain has two fully functioning halves that do everything a full brain needs, but tend to develop in different paths. From birth the two halves will learn to react differently to stimuli, insuring the different personalities form unique to eachother. Each set of eyes is related to a personality, and whichever pair is open is the personality showing at that moment. Each one usually will take on a different name, and the trick about dating one is you have to find basically 4 personalities which get along well with eachother. Because of this, it's often times that they are polygamous in nature, each personality taking on a partner they fit best with and those two partners doing the same, though occasionally a perfect match can be found and they remain monogamist or possibly only in a three way relationship. The switch between personalities is quick without warning, all it takes is one pair of eyes to open. The dominant personality cannot communicate with the recessive personality until they switch, communicating through forms of writing. Occasionally when in a threatening situation both personalities become dominant and they work together to keep themselves alive, however this can be confusing for most to control and is usually deemed more trouble than its worth. However, some choice few are able to keep both pairs of eyes open at all times and equally share control at all times, merging into one, and these usually grow up to be the leaders of their nations.
