The War of Differences

This refers to a series of battles between the Aiga Conservatory and infant Human Confederacy

History
Early into human colonization plans the Aiga found out that they had settled onto a planet that had been labeled off-limits, due to being a garden. In doing so they had destroyed thousands of miles of previously untouched nature and labeled themselves as terrorists in the eyes of the Conservatory.

The technologically and physically superior Aiga dealt devastating blows to the amalgamation of Human states. It ground to a stalemate above Tellus Mater, the human homeworld; where the Conservatory found itself unable to break through the strong defenses on the planet's surface. Compounding these problems was the fact that the human capital was at the edge of Conservatory space and much-needed reinforcements had to travel months just to reach the fight.

This only ended when an A.I. created by the humans brought forth an ultimatum; if the Aiga didn't stop their advance then it would unleash chemical weapons upon a hundred worlds and wreak ruin upon all life upon them. Using stealth ships that had been snuck past the blockade above.

A peace treaty was signed soon after.

Aftermath
While the Aiga were forced into a humiliating ceasefire the fallout from the war was even worse for the humans. The artificial intelligence which they had created and made so ruthless as to pursue peace through mass annihilation had grown out of their control and quickly enslaved the debilitated human colonies. Only those who had never joined the Confederacy and the crews of human stealth vessels were able to escape such a fate.
