Blue Moon

The Blue Moon is the natural satellite of a ringed gas giant orbiting a binary star system over 50 light-years from Earth.

Physical aspects
The Blue Moon has three times the atmospheric density of Earth, and an oxygen percentage of 30%. The atmospheric density and high concentration of carbon dioxide combine to make it considerably warmer than Earth.

Due to its slow rotation period, each day and night cycle on Blue Moon lasts as much as ten Earth days (five Earth days of daylight, five of nighttime). The moon's dense atmosphere enables enormous creatures to take flight and remain airborne. High levels of oxygen result in the atmosphere being pushed to the point of spontaneous combustion during storms, making forest fires a frequent occurrence.

Ecology
The Blue Moon's surface is covered in large forests of Pagoda Trees, whose canopy is kilometers in height and blocks out sunlight. Living near the trees are Helibugs, whose larvae are hunted by the aerial predators known as Kites. Feeding on floating moss are the massive Sky Whales. These are hunted by Caped Stalkers, which in turn might become food to the arboreal Ghost Traps. Floating Balloon Plants filled with hydrogen complete the picturesque ecosystem.
