The heart of the Terran empire is a hot desert planet littered with Oases. It is one of five planets that orbit a black hole called Gravita. It has a single moon named Arcadia. At the center of this wide reaching civilization is Tera Centuria, a glorious and towering city surrounded for miles on all sides by harsh dunes that lead into towering walls and watchtowers before fading into the Metallic Forest. Arcadia is home to the grand military academy of the Terran Army. The people that live here are hearty and noble, and their leader, a charismatic champion on the people. There are many abandoned Terran facilites that have been taken over by the Mercenary group Gravita's Pull.
