The Gaoul, from the planet Sesharrim, are an ancient race of sapient flying creatures with an appearance reminiscent of a red humanoid pterosaur. They have membranous wings, four-fingered hands and an eagle-like beak, and appear to be incapable of speaking (at least not the same language that is used by the all the other non-Drej races of the galaxy). Several of the Gaoul were shot down when the Drej attacked their planet. As the Drej pursued the explorers which the Gaoul were trying to protect, one of them smashed into a hydrogen tree, a plant or fungus like species native to Sesharrim, causing it to explode, thus killing itself. However, the Gaoul also took down many Drej Stingers by clipping loose hydrogen trees to float into their path.
