The Colony War of 2129 began after the newly formed space colonies demanded independence from the earth and it’s nations. After a one year war the war was brutally ended by the colonists with attempted genocide of the earth’s inhabitants by emptying three colonies and dropping them on earth. The resulting explosions successfully destroyed the surface of Earth within 95% of the population. The actual damage is unknown as all contact from satellites were cut off after the attack. Scientists theorize that other than Century Station, nothing survived on our planet.
It was through the valiant efforts of The Sentinel that the city was saved. By giving his life, he shielded the city and allowed for our lives to continue.
