As the Independent nations crumbled and the invasion of Helios continued, more and more people began to flee to the inner systems of the Confederation, finally converging on Sol.

The Pandoran fleet arrived in Sol on 26th December, 2624, bringing with them their entire weight - thousands of starfighters and warships. The fleet jumped in to the vicinity of Earth, ignoring Mars and other formerly inhabited planets and stations.

The allied forces gathered there defended Earth, the Pandoran's ultimate target, in an engagement that became known as the Battle for the Solar System. The battle ended only a few hours later when Dragon was destroyed by the prototype TSB bomb, and the remains of the Pandoran fleet retreated.
