Seventh Galactic War (Battle for Earth: Prime)

The Seventh Galactic War , also known by some as the Centrian War was a pan galactic conflict waged between several powers across the galaxy. Devastating hundreds of planets, the war waged for years, resulting in the deaths of millions of soldiers and civilians. The first war spanning the galaxy in millions of years, since the times of the Sixth Galactic War, the war would would escalate to include several powerful nations.

Although the war was fought initially between the Cyclarchy of Centria and several smaller nations, the war would eventually turn into a galactic conflict with the introduction of the Grand Coalition, a military alliance dedicated to ending the Cyclarchy of Centria's aggressive conquests across the galaxy.

The Centrians continued their conquests of the Promethean Empire, before turning on their allies, opening fire on Praetorian ships in the area. The aggressive Centrian actions eventually led to the created of the Grand Coalition, a military alliance headed by the Meridian Consul, dedicated to subjugating the Centrians and preventing them from ravaging the galaxy. Ultimately belligerent nations knew that the war would establish a future regional power, with either the Centrians or Meridians growing immensely in power- perhaps to the point of the next Superpower.

Battle of Luna
By the winter of 1965 the Promethean Empire had reached the Solar System with a small fleet of heavily armed ships. The Prometheans, prepared to destroy the Human planet of Earth, positioned itself near the planet ready to use force to destroy the race.

The entrance of the Promethean fleet into the solar system was detected by the nearby Centrian base on Titan, the largest moon of the planet Saturn, fortified by the presence of the 3rd Assault Fleet, 7th Assault Fleet, and 23rd Assault Fleet, the 8th Battle Hive, 9th Battle Hive, and 92nd Battle Hive, and the 4th Grand Fleet, and the First Sigma, an elite unit of the Centrian military noted as being comprised of the most elite ships and soldiers in the nation.

Early communications were rejected by the Prometheans, who continued on their course toward Earth. Sensing that the planet may be in danger, the Centrians threatened the use of force to stop the Prometheans if they did not state their intentions.

As the main Promethean fleet neared Earth, fighters from the Praetorian base on Luna were ordered to engage the invaders, hoping to stop them before reaching their target. After a series of short waves against the Prometheans, their fleet was ordered to halt and prepare for bombardment from Luna. Several Promethean ships eventually opened fire, beginning a long engagement over the barren satellite below. With smaller ships and destroyers caught up in the fighting, several large Promethean battleships and carriers were able to be targeted by Lunar defenses and support ships, leading to the immediate crippling of much of the nearby fleet.

As the Promethean ships reacted to effectively combat the attack, several groups of Praetorian fighters were pushed back, allowing an opening in the Praetorian defenses. Beginning to take the upper hand, a landing was eventually ordered on the Lunar surface. The Promethean ground forces, who were preparing to scout out the destroyed Earth primarily, and lacked ground support vehicles and other amenities were slightly outgunned. The Promethean troops were eventually pinned down in their landing sites, making missile strikes difficult.

After a stalemate on the ground resulting in little gains, and a potentially crippling battle above, the Prometheans ordered a general retreat from the Solar System. The Praetorian fleet in the region immediately docked for repairs, hoping to replenish their fleet after the devastating charge resulting in a Pyrrhic victory. The Lunar surface also suffered heavy damages, resulting in the temporary disabling of an able bodied defense on the ground.
