Setras is one of Aphrael's cousins and a Younger God of Styricum. He appears briefly in The Shining Ones and The Hidden City, but is not otherwise of major significe to the plot. Setras is the Styric God to whom the Alcione Knights (of which Tynian is the Champion) submit their spells.
Setras appears to be an artist, continually working on creating "sunsets". While he is a deity, he appears to be of somewhat limited intellect and rather easily distracted and seems somewhat befuddled by mortals.
