Terra (previously known as Earth) is the 3rd planet from Sol and hosts liquid water. The surface was swarming with life, much more than other planets. Several million years ago the species known as Terrians emerged and quickly dominated Terra as the most advanced and strongest life form. Terrians made first contact with the Turukai through exchanging radio messages.
During the War Terra was Photon bombed when the species known as the Vaniak broke through the Terrian defenses. Terra has been evacuated and is now only a shell of what it once was, it will most likely take life 2,600 years to fully recover.
