The Rodian Karstag was a predator, native to Rodia, that inhabited swampy and damp forests. An adult was about 1.5 meters in height at the shoulder and between 4 and 5 meters long. Despite the animals bulky appearance, they were deceptively fast creatures. They had scaled bodies that were supported by four powerful membranous webbed feet that aided it locomotion in water and swamps. The Rodian Karstag was hunted for sport during the annual Vor-cal on the planet Vilhon in the Tapani sector. It was served roasted with Algae-bread stuffing at the Vor-cal Feast.
