The Aash'n evolved from a carnivorous species but are now omnivores, with much of their diet being plant life. Their unique motor system is the result of their carnivorous nature; their torso is hung between a pair of tall, powerful legs which allows them to stride large distances whilst reaching for prey with shorter arms ending in large but dextrous digits. Their primary neural functions are, like humans, contained in a head which rises atop the main body and is equipped with eyes and ears, a mouth and nostrils. They have more acute vision and hearing tha humans but, partly as a result of thousands of years of homogenous diets, have lost much of their sense of smell and taste.
