Terra

Background
Terra is the official name of the solar systems containing planet Earth, however the planet is often also referred to as Terra. The system contains eight planets, of which four have been colonized or terraformed by the RSC. The outer four planets are gas giants, however moons of each have been colonized. Terra is the home to Humans. It contains a singular G-type star.

Inner Planets
The inner 4 planets of Terra have been colonized by Humans. Mercury was colonized in 2151, and terraformed in 2190. Venus was colonized in 2096 and terraformed in 2138.

Earth
Earth, also known as the planet Terra, is the ancestral home of all Humans. It is the epicenter of their evolution into an intelligent species.

Mars
Mars was the first successful colonization and terraformation made by Humans. The TC colonized the planet in 2029, and successfully terraformed it in 2075. Most notably, it contains the ruins of Blood Keep. Blood Keep was an outpost in Argyre Basin, and served as the main military hub for the newly founded RSC on Mars. Its original name was Bloode's Keep, named after after General A. Bloode of the RSCA. The name was changed in colloquial language after the attacks by the Kashni Empire on the outpost in 2223, 4 months before the declaration of war between the two factions. The attack marks one of the few examples of casualties from the war.
