He comes from the planet (or race of) Sthri, about 80 light years away. He has gleaming emerald eyes in a triangular dragon's head. Otherwise he looks like a dragon with wings and a tail. In human form, he looks somewhat like Col. Sanders. He's super-intelligent, capable of doing several things at once, and can disguise himself. Beyond that, who knows? He's a major contributor to and Trustee of Whateley Academy. There's a picture of him in the passage from Shuster Hall to the Crystal Hall. He's shown in dragon form sitting on his hoard.
