Madrian – The Madrian are an ancient species of Tranthaea, who have ruled it for thousands of years. Most of the names and places are in the Madrian language, which is low, rumbly, a mixture of growls and thuds from deep within the throat. As a species, the Madrian are uniformly tall, averaging about 10 feet high. Their bodies are covered in a loose, auburn hair and they have long, flat faces, into which are set rich, dark eyes over a muzzle with two long fangs protruding over the lips. They have four arms, air sacs on their shoulders which inflate when they are angry or feel threatened, tufted ears and eyebrows, and wings of purple feathers that stretch in a 9 metre wingspan. The last two surviving Madrian are Dauld and Tosh, the Dyadem, who rule Tranthaea during the arrival of Gabriel Sorensen. (See also Dauld, Dyadem, Tosh)
