Origins
Well before the first official contact between the Planetary League and the Convergence, there was a latent hostility between the Convergence and humanity. It stemmed from an incident in 1947 when a Convergence scout ship was temporarily disabled in the desert of New Mexico from radio interference. Ever since that time, the Convergence would occasionally send raiders to the unsuspecting Earth to play a series of mean-spirited pranks on the locals.
The direct roots f this conflict, however, began when a colony ship from the Planetary League arrived at New Promise in GSC 130. The human populace, essentially unaware of the Convergence’s very existence started to set up their technology and habitations on New Promise, including items that created the radio interference that disrupts the hive mind of the Convergence. The Convergence, for their part, had set up their own bases near the rogue planet Dogur-dann less than a light-year from New Promise.
When the Convergence realized that the humans were moving in on New Promise, they decided to launch a harassing offensive to drive them off. This is how the first convergence war started in GSC 132.
The Convergence Onslaught
Starting in GSC 132, the inhabitants of the newly settled agricultural colony on New Promise started experiencing a series of strange and terrifying phenomena, many of which were consistent with former reports of UFO sightings from previous eras on Earth. Strange, saucer-shaped craft were sighted in the skies, people were abducted and experimented on, livestock were mutilated. Panic spread through the colony. The local fleet of the PLIN was deployed, and a makeshift planetary defense force was hastily mobilized. Distress calls were sent to Earth, but the time for help to arrive would be measured in years before the development of FTL propulsion and communications.
Turning Point
For three frustrating years, the Planetary Defense Force fought against the convergence, with little to show for their efforts. Then, in GSC 135, a major turning point occurred when a Convergence ship was captured. In a matter of months, human scientists and engineers were able to reverse engineer Spatial Compression, and FTL communication technologies from the captured craft. With these new technologies, the Planetary League was able to mount a meaningful counteroffensive.
The Dogarri
Following retreating Convergence ships to their home base, in late GSC 138, the forces of the Planetary League discovered Dogur-dann, the home-world of the Dogarri nearby. The Convergence had been conducting a predatory series of raids on this planet, designed to gradually break the will of the Dogarri, and subject them to Convergence rule.
In early GSC 139, the Planetary League passed the Alien Assistance Act into law, creating the Alien Assistance Agency, and authorizing assistance to alien beings in need. Quickly, the Planetary League and the Dogarri formed an alliance to fight their mutual foe. After this point, the combined forces of the Planetary League and the Dogarri were able to fight off the Convergence with relative ease.
The End
The final battle of the war was the battle of Key Center in GSC 140. During this battle the Planetary League battleship fired the massive, Dogarri-engineered dispersion gun, destroying the Convergence mother-ship, and carving the 100-Meter Canyon.
