Planet Eunomia—nicknamed after the Greek spring-time goddess of green pastures—is a habitable planet and the second planet in the Alpha Centari A star system. It has approximately 0.8 times the mass of the Earth and an orbital period of about 420 days. The planet is notably green, its surface covered by lush forests and emerald-green oceans. The average surface temperature is about 9~14°C warmer than on Earth, its poles containing little to no ice. Eunomia’s atmosphere is characterized by very high levels of carbon dioxide and methane, and the oxygen present in its atmosphere is almost double that of the Earth’s.
The Dryads are the native humanoid inhabitants of Planet Eunomia. Unlike Earth, there are no animals on Eunomia; rather, evolution within the Eukaryotic domain developed solely into Fungi, Plantae, and other non-animal, eukaryotic groups. A group of plants later branched off to form what is known as the “animaplants,” a division of animate plants that fill the ecological niches generally attributed to animals on Earth. Dryads (Dryas sapiens) are a species of animaplant, and are the only known Eunomic organisms with human-like intelligence.
The biology of dryads, unlike humans, makes it very difficult for them to live outside of specific environments even with the aid of tools and technologies. For this reason, the dryadic domain and the diversity among dryads are not as grand as they are for humans on Earth. Furthermore, the average lifespan of dryads are much longer than the average human lifespan, averaging a few centuries, and results in slower cultural and linguistic changes among their groups.
