Arrawns differ a lot from other intellectual races. Having come to the planet from the depths of the space, they are ideally fit to survive under any, even the most difficult, circumstances. They are tall creatures, having two pairs of operating limbs and a strong tail, but completely lacking sexual characteristics. A strong defensive shell, covering bodies of arrawns, protects them both from temperature changes and bodily damages. Special pores, able to perceive light, warmth and smells, successfully take the place of eyes and other sense organs, while special glands, secreting powerful poison, serve as great natural weapon. Arrawns can not talk, as they have no mouth, but are able to communicate telepathically, due to which they continuously maintain mental connection with one another. Representatives of this race perfect their body through implanted biological symbionts, which, in particular, can act as weaponry or armor.
