The Sabat tribe of the Arabian Desert are nomadic and uniquely solitary. They travel constantly, alone or in small family groups. Through the tribal code they are forbidden from speaking with outsiders.
Their jewellery is used to signify a member of the same tribe when passing each other alone in the vast tundra. Having established a fellow Sabat they can trade and learn where to camp and the location of food and water sources. The jewellery also helps to facilitate the meeting of members of the opposite sex.
