Sidra

### Air

Nitrogen, Oxygen, Carbon Dioxide (>18%), Xenon (6%), Methane and Hydrogen Sulfide (>1%).

Sidra is a magical planet and the third one orbiting the star Illios in the Kepler system, located in the Cosmos Galaxy, approximately 13 billion light-years from the Solar System in another dimension. It's the largest and most massive of the four rocky planets (with its size roughly between Earth and Neptune). It's the native realm of Astros, along with other exotic and magical creatures and plants. All territories of Sidra use the same currency, Alexandrite.

## Fauna and Lifeforms

Other than the richness of varying colors, the fauna resembles those of Earth. They have the familiar trunks, branches, and leaves, though many of the shapes are strange and have more significant proportions. Sidra's wildlife also has bioluminescent qualities. Sidra looks like a lush paradise by Earth standards during the day, but at night, virtually all life on the planet exhibits bioluminescent qualities in various colors.

## Day-Night Cycle

Sidra receives significant light from Illios. As a result, Sidran nights are never dark during half of the year but instead are more like Earthly dusk. At the closest point in its orbit, Illios 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. Truly dark nights are uncommon. Sidra occasionally eclipses Illios at night for about one hour and 40 minutes, but the light reflected by the planet still keeps the night from being dark. Because of its axial tilt (Between 22° and 29°), Pandora exhibits considerable annual variation in the day-to-night ratio. In addition, its elliptical orbit produces seasonal temperature variations and a range in daytime illumination of about ten percent.

## Geography

Sidra consists of one continent with an area of 149,570,030 km (57,771,910 sq mi) and is surrounded by water from all sides. The continent is divided into 12 large Astro territories and surrounds the neutral megacity of Asteria.
