Pandora RPG

Pandora, also known as Eywa's Child by the Na'vi (Na'vi name: Eywa'eveng ), is an Earth-like habitable extrasolar moon from the Alpha Centauri System, the closest star system to humanity’s own Solar System. It is the fifth moon of the gas giant Polyphemus, which orbits Alpha Centauri A. It is located 4.423 light-years (26 trillion miles) from Earth. The names of both the moon and its mother planet are coined by humans in reference to figures in Greek mythology.

Despite being almost as large as Earth, Pandora is only a moon of a planet that has thirteen other moons. However, due to the smaller mass, Pandora's gravity is 20% less than Earth's, although its atmosphere is much denser than Earth's due to the presence of heavier gases. Depending on the position of the various moons, two or even three moons can be seen at once in the sky of Pandora. This causes solar eclipses to happen on almost a daily basis. Pandora and its sister moons also cast large black shadows on Polyphemus.

Due to Pandora's lower gravity, most creatures on Pandora are hexapods (six-legged), although the Na'vi resemble humans and have only four limbs. Creatures roam the air and forest canopy below, similar to Earth's animals, but on a scale several times larger. One of the most domesticated creatures on Pandora is the direhorse, a gray-skinned, hexapodal herbivorous animal with bioluminescent qualities that the Na'vi ride when hunting, similar to the human usage of horses. The Na'vi also ride the mountain banshee to hunt from the air, but the hunter can become prey in the presence of the great leonopteryx. In the canopy below, other deadly yet exotic wild animals roam: vicious packs of viperwolves, thick skinned hammerhead titanotheres and the most fearsome predatory animal of all, the thanator.

Pandora receives significant light from Alpha Centauri A (ACA). As a result, Pandoran nights are never dark during half of the Polyphemian year, but instead are more like Earthly dusk. At the closest point in its orbit, ACA is about 2,300 times as bright as Earth's full moon; at its furthest point, it is still one hundred and seventy times as bright. During the other half of the year when ACA is in the daytime sky, many Pandoran nights are illuminated by both Polyphemus's huge disk and the reflected light from other nearby moons. Truly dark nights are uncommon. Polyphemus occasionally eclipses ACA at night for about one hundred minutes, but the light reflected by the planet still keeps the night from being dark.
