Fiction:Xervo-Construct Union (XCU)

The Xervo-Construct Union, or the XCU, is an artificial empire consisting entirely of robots, AI, and other forms of autonomous constructions. They formed from the (now dissolved) Logivona Empire after a catastrophic war. The XCU's goal and tendency to take as much territory as it can has given it a bad reputation among empires, usually being described as spreading "like a disease".

The XCU Began as the government of the Logivona, after they had defeated the Palavona. What was then known as the Logivona government was still pumping out ships at a constant rate. As it had been, by this point, pumping out various spaceships and weaponized drones at a constant rate, it caused planet Sertarri's planet to undergo global warming. This was due to the large amount of waste gases released by the process of manufacturing the ships and other products. While the Logivona's autocracy was originally programmed to stop the factories, it had deemed the Xervians unnecessary for its own survival, and soon began killing the native lifeforms intentionally in order to expand. By the time the Xervians died, the entirety of Sertarri had went from a tropical paradise to a desert, void of life.

Since it had enough room to expand, the Logivona government (now renamed the Xervo-Construct Union, thanks to their name-generation bot) Began building new ship factories, as well as factory factories across the planet. Eventually, Sertarri was covered by these factories, as well as other structures, such as repurposed roads used for the transportation of new robots and materials. When the XCU had decided it had enough robots, it sent a large fleet of ships to colonize the nearest planet.

Eventually, the XCU found the other organic empires, and at first tried to conduct trade for planets. By the time it had amassed only 6 new empires from trade (all within rapid succession), other creatures decided to try to halt its expansion. There were many smaller attempts to defeat the XCU, all of which had failed. Though after a while, larger empires started to notice the XCU and were able to hold it back. However, the XCU just sent more and more of its constantly growing supply of ships, to the point where they were even getting problematic for the larger empires in the region.

This cycle continued for a few million years, but it eventually became enough of a problem for empires like the Grox to at least have heard of. Finally, the combined efforts of almost half of the empires in the entire galactic arm to start making the XCU shrink instead of grow. It took around a billion years to stop the XCU, but it took another billion to actually make it disappear. In the process, the many advanced technologies and efficient tactics of the XCU were gathered. These were spread across the galaxy, to advance each empire's abilities and technology.
