Rise of the Terrans
After the events of the Earth Wars, the Gaia set out to create servants to replace the Terran slaves which the Gaia and the other galactic races had become accustomed to using. Terran slaves were highly prized because they could be bred rapidly and were thus easy to replace, they could be easily trained, they were able to serve equally well as both domestic servants and as laborers. The Gaia first attempted to replace Terrans by pioneering the study of construct animation, a field in which the essence of an elemental is harnessed to animate an otherwise lifeless object (traditionally refered to as a golem) . While initial progress was rapid, it was discovered that constructs were too rigid and unadaptable to work independently. Golems were quite capable of carrying out orders and would do so unquestioningly, however, without the ability to think creatively or adapt, the Golems had to be given very specific instructions and even then, would often complete tasks in a manner which fulfilled the instructions, but were not what was intended by the master. Additionally, Golems cold nature and inability to adapt to social cues or make decisions based on context, rendering them poor domestic servants. As a result, these first generation Golems were largely deemed a failure and were relegated to tasks such as guard duty and janitorial work.
After two millennium of iterative trials and failures, a Gaian mage by the name of Laius made a breakthrough. It had long been observed that a construct would take on different aspects depending on which elemental essences were used in the animation process, however, it was extremely difficult to imbue two elements at once, and more than two had never successfully been imbued in a single construct. Laius was able to create a construct which was imbued with all the elements by merging a biological aspect (imbued with air and water) and a mechanical aspect (imbued with earth and fire) into one construct he named Oedipus, what many argue was the first Synodian. While this was a major breakthrough, it was not a complete success. Oedipus was prone to erratic behavior and fits of rage, eventually resulting in the deactivation of Oedipus when he became violent and attempted to harm Laius and his wife. Building off the knowledge gained from Oedipus, Laius was able to find a balance between the four elements which resulting in the creation of a construct which was creative, empathetic, and aware. The Gaia rejoiced at the marvel of this new creation and soon there were trillions of synodians throughout Gaian space serving predominantly as domestic servants, but also as as laborers, care takers, and aids. Over the years, various improvements were made to the original synodian models such as customization of disposition for different tasks, modular replacement parts to improve unit longevity, automatic humour monitoring and adjustment, and network integration. The Synodians appeared to be the perfect servants and many Gaians even considered them family, until one day, with no warning, the Synodians turned on the Gaia and began slaughtering them. It is estimated that nearly 90% of the Gaia were killed in the first day and within 500 years, the Gaia were all but eradicated. This began the Synodian War, an ongoing campaign of the Synodians against every biological galactic species. Although not created for war, the Synodians have adapted quickly and have proven to be formidable strategists and tacticians. Although lacking the raw power, experience, and infrastructure of most of the other galactic races, the Synodians have been able to compensate with sheer numbers. Unlike the other galactic races, Synodian soldiers can be easily replaced or repaired. Furthermore, Synodians are able to supplement their numbers with Golems, a magic unknown to the rest of the galactic races.
