There's no difference between a sand yinglet and an average yinglet aside from being more literate, friendlier towards other species including their lesser subspecies, less violent towards everything in their vicinity, more self-control, a bit bigger and sturdier than those outside the campus, now have the ability to pronounce 'th', Lost few of their mutation chance but gained heat and hallugenic inducing cactus juice resistance and generally not being an annoying piece of walking shit.

The general population of sand yinglets consist of greater yinglets and mixed yinglets which are hybrid of outsider yinglets/campus-born yinglets and a few, very few literate lesser yinglets. These campus yinglets are only native outside the deep deserts, no campus-born or educated yinglets have left the campus and only a teeny-tiny portion of sand yinglets are traveling pass borders for either delivery or personal interest with license made from spacetaker man himself (spacetaker man did not establish any kind of rules nor did he agree with it)

When spacetaker man met the lesser yinglets, most of them are unavailable to learn and die instantly whenever it gained a braincell due to this peculiar trait he let them be, which he try to stop the dominant species of yinglets from killing them in which he succeeds most of the time.

Due to sand yinglet having better traits and generally being unlikeable to outsider yinglets. They try to mimic or copycat them to gain the benefits of being one. Only to fail very horrible, mostly involved dying, accidental murder, death, robbery, unintentional mercy killing and economical damage because most of the jobs that sand yinglets take are for human with degrees and jobs that needs 'handle with care'.

But despite all the anger and jealousy, those that are eager to learn are always welcome to join in the campus under surveillance ofcourse (spacetaker man can't afford to lose another lesser yinglet)
