The Alliance is a collection of multiple races and governments that originated from the Milky Way 1.9 billion years ago. During that time, a powerful force known as the Terridaxians were fighting three bio mechanical peoples: the Nuva Nui Republic, the Tekanan Empire, and the Voidican Imperium. The three races decided to work together and defeat the Terridaxians, and the Alliance was born. Within two months of the formation of the Alliance, the Terridaxians lost and the first Terridaxian war was over. Shortly afterward, other peoples such as the Tetran Empire, the Rising Sun, the People's Republic of Partaracia, and many others asked to join the new superpower. Within one year of its formation, the Alliance grew to become the most powerful force the Milky Way would know for more than a billion years. However, about 500 thousand years ago, the Alliance learned of the evils coming to the Milky Way, and knew they couldn't survive a direct war. So, they fled to the Magellanic Clouds and neighboring galaxies, and protected the Milky Way by occasionally sending warriors to it, but tried to keep themselves as much of a secret from Entropy and the Terridaxians until they knew they could beat them. There, they gained new allies and brought new races into the Alliance such as the Vexian Warmind and its forces, the Entarian Empire, the Democratic Leadership of the Globular Clusters, and many others. During this time, the Terridaxians decided to attack again, and brought a secret weapon with them: a chaos being know as Entropy. Shortly after the war began, Entropy betrayed the Terridaxians and formed a cult that would last to this day. Eventually, he was forced into hiding by the legendary SilverPulses. Now the war with Terridaxia is over, and they became part of the Alliance. Their troops now work alongside other races, and have for over 40 thousand years. Then, in 501 ACE(After the Cyprus Event, or the death of Cyprus) one of their greatest warriors, Silver, who was a member of Cyprus, went missing. The Shadowed One was dispatched to find him, and help the other SilverPulses end the civil war that raging across the Milky Way. He was freed by Wheatley, a wisp, and aided in the Alliance's secret assault in the Battle of Crux, the last battle of the war. Now, that war is over. They have bases and territory across the Local Group the Milky Way is a part of, and a few small territories outside the local group. Their main concern now is to help rebuild the Milky Way after its war, and help the Infinite Pioneers in their quest.
