Alien races:
Styor- 'Physically they were humanoid enough to pass at least as cousins of the Terrans. Mentally and emotionally the two species were parsecs apart.'
Ikkinni- natives of Klor. '…perhaps Kade's height, but the length and slenderness of arms and legs gave an illusion of added inches. Body and limbs were covered with fine, long black hair though which white skin showed pallidly. The hair was heavier on shoulders and chest, rising on top of the head into a peak of coarser, stiffer growth. On the cheeks and chin the sprouting was soft down from which a hard beak of nose protruded in a bold curve, overshadowing the rest of the features. A wide, seemingly lipless mouth was a little open, and teeth, certainly those of a carnivore, matched the skin of whiteness.' 'red eyes'
