Ares

Mars is the fourth planet in the Sol system, and considered by some to be Gaea's 'twin'. Before Humanity was dragged into the war between the Harbingers and the Eteno and Dhragolon, Mars was an uninhabited world covered in iron oxide dust. After the War on Gaea, the Eteno took ownership of the Sol system and began terraforming Mars in 2353, and completing the project in 2418 ATGW.
