The kyren was an insect native to the planet Ansion. They were almost jet black with four membranous wings, two large at the front of the thorax and two smaller ones at the rear. The kyren would glide on the upper wings while being propelled by the rear ones. A bright yellow splotch decorated each wing, which was believed to be an aid for identification. They were legless, and instead boasted a pair of thick, furry tufts that ran the length of its underside, like runners on a sled. Since they were airborne for most of their lives, the kyren had little need for legs. The kyrens mouth was large for its bodysize and was lined top and bottom with twin ridges of horn. The kyren traveled in swarms of up to and sometimes over 150 million individuals. They traveled the grasslands of Ansion in search of food, using their horned mouths as scythes to slice the grass and plants growing on the plains. Kyren swarms did not move to avoid any objects in their way, and thus despite their herbivorous nature were highly dangerous to any creature that could not find proper cover to hide behind.
