The Frills are native to the planet Gemworld, this race of tall humanoids was distinguished by their unusual skull structure. A tall bony ridge extended nearly a meter in length from the back of their head, and their lower jaw also jutted outward with a bony ridge. The Frills were exceptionally tall and lanky, standing about four meters in height, with a muscular tail that helped them keep their balance. This physiology pointed their ancestry, as the Frills were descended from herbivores that fed from the chiliox trees. Fills continue to exist as vegetarian ruminants, as each individual processed their chewed cud in no fewer than three separate stomachs. The skin of an Frill was capable of changing color, and the areas around the crest were especially adaptable. The color changes expressed by a Frills emotions were basic enough that other races and species could understand them, a fact that meant many Frills were poor sabacc players and negotiators. Many politicians took to wearing crest cloaks in order to hide their true emotions. As a species, the Frills were known to be courteous, serene beings who rallied around whatever group they were a part of.
