The Callen are a quintepedal species, derived from radially-symmetrical and tree-like ancestors. They are one of the older races of the Sentros Galaxy, having hundreds of colonies and being one of the founding races of the Pan-Sentros Alliance. Their homeworld is Ma'tat.
Callen have five legs- one leg at the front, two at the back and two larger legs in the middle. Each foot has a single clawed digit on the end. Their skin has colours ranging from red to black, and has a covering of short, thin hairs that are barely noticeable. Their heads have six tentacles that they use to transfer food into their jawless mouths. They have two useable arms, each with five fingers, and a vestigial arm on their back that they can hang from (usually while sleeping). Callen are a predatory species, having meat (or synthetic replacements) form the vast majority of their diet. The average individual is about 1.5 metres tall in males, and 2 metres tall in females.
The Theocracy of Ma'Tat is ruled by priests, elected by the government for their skill in that position. They rule using the rules of the T'maitanat, a book that describes the history of the Church of T'mait and the god T'mait itself. While this form of government is considered odd and sometimes oppressive by others, it usually works out quite well in practice- priests must swear themselves to a life of poverty and goodness in the name of T'mait, which helps prevent the corruption that the Theocracy believes is inherent in most polititians.
The Church is a part of life within the Theocracy. Although other religions are permitted, public preaching and churches are not approved of and can result in fines. The vast majority of the Theocracy's population (judged to be around 80%) worships T'mait, and a third of that is devout worshippers.
Callen are a hearing-based species, and so their arts are best-known for poems, songs and instruments. Callen tend not to cook their meat as thoroughly as other species do, and they are known for having a sweet tooth. Callen painting and drawing is commonly either abstract or realistic, as the T'maitanat views these forms of art as pleasing in T'mait's eyes.
