Mars

Mars is a planet in the Saturnverse and the home planet of High Emperor Celestia. It is the center of the S.U.N. (Solar Union of Nations) and acts as a hub for all interplanetary affairs.

Description
Originally a vast desert planet, Mars was conquered and developed by the Celestians. It is now covered in massive cities of white stone that reflect the light of the sun. These cities are surrounded by artificial lakes and rivers which supply the surrounding farm lands with water. Beyond the farms are vast jungles of tropical plants and beyond that is red desert. Celestian Pegasi control the weather near colonies allowing them to flourish as agricultural centers. Outside of the cities are jungles of lush foreign plants, planted by Celestia's servants to make the planet appear fertile to it's citizens. Beyond the jungle is the vast and empty red rock deserts of Mars which are mostly devoid of life.

History
Originally Celestians were not the dominant race of Mars. Martians were the first inhabitants, tall and muscular deer people similar to Neptunians (see Penny). The race enslaved all of the Celestians and forced them to work in mines and fields for them. After nearly ten-thousand years of enslavement, a young Celestia rose up as a leader among the slaves along with her sister Luna. The two horses would lead the rebellion against the Martians and win, conquering their cities and freeing the Celestians. They would then elect her HIGH EMPRESS and rename themselves as a race after her. However, Celestia was not the kind ruler they wanted and instead brainwashed the people, using them like slaves to build her empire and cultivate the planet.

Emperor Celestia would later perfect interstellar travel and use her standing military to conquer other planets and assimilate them into S.U.N. Her rule would further strengthen her empire and her home planet. Mars would become the hub for all planetary trade and the center for interplanetary governing.

2004 Reboot
