The Frills are a peaceful, diminutive humanoids from the planet Gnorin. The Frills consist of two species—one, a Near-Human race, the other a floppy-eared, furred humanoid species. Though the two species were completely unrelated biologically, they shared a language and cultural identity as Frills.
One of the Frills species was thought to have evolved on Gnorin. They are slightly taller than the Near-Human Frills, with an adult height of 1.0 to 1.6 meters (females being slightly taller on average.) They are covered in short fur, ranging from black to tan in color. Their faces had floppy ears, long muzzles, and small black eyes. They have three long fingers and a thumb on each hand.
The Near-Human Frills differed from the Human norm primarily in their short stature (1.0 to 1.5 meters for adults of both sexes.) Near-Human Frills are often said to resemble Human children, though males frequently (and proudly) grew full beards. Xenobiologists believed that the Near-Human Frills arrived on Gnorin from a nearby planet and adopted the culture of the original Frills species. No other animal species on Gnorin was related to them genetically.
Both species called themselves simply "Frills" and lived harmoniously with each other in their shared forest cities. They considered themselves to be a united people, and were considered as such by the rest of the galaxy. Intermarriage between the two Frills species was not uncommon, though genetic incompatibilities required such couples to adopt if they wanted children.
