I can't really give you a good description since they are humans (And I was not aware humans required art). They only differ from Nepleslians in that they are descended from different racial stock. So it varies widely.
I mean I can just give you a "tiny" bio example off the top of my head.
Female Sahaad:
Age: 25
Height: 5'7"
Weight: 125 lbs (56kg)
Hairstyle: Long (Say to the middle of the back), straight, black. Bangs are trimmed and hang just a little above the eyebrows. Tied back in a loose pony tail.
Eyes: Dark green eyes with the barest of tilts to just barely give off an almond shape.
Face: High cheekbones, a small aquiline nose, cupid bow lips of a dark rosy hue. Clear skin free of blemishes with an olive complexion.
Figure: She is a little on the slim/slender side with bare hints of feminine curves.
Measurements: 33B-23-33 (83-58-83)
Male Sahaad:
Age: 36
Height: 5'10"
Weight: 174 lbs (78kg)
Hairstyle: Gray hair with a style reminiscent of a slightly longer crew cut with a little messiness thrown in for flair.
Eyes: Soft blue eyes.
Face: High cheekbones, hawkish nose, squarish jaw. Has five'o clock shadow (stubble). Thin lips.
Figure: Tall with an athletic build of a person who works out on a regular basis and takes care of himself. No flab, but definitely capable of seeming muscle if you look.
Clothing for either I don't even know. Just normal street wear maybe.
Not that great I know but it is off the top of my head. If you want more just PM me possibly.
