Trion is not much of a civilization, but a SuperAI. No other civilization knows where this AI came from, when they were first discovered they had already colonized the entire system of Un. The AI works like a hivemind, everything is the AI. It should be noted that it is possible for robots to be separated from the AI, and to develop their own personas. The AI isn’t interested in trade or conflict, it seems to simply pursue a directive of research. The AI researches and develops new technology, to make itself more and more advanced.
The Trion AI was created by an ancient empire, to help automate its systems. This ancient empire made a “Trion” of AI, one for research, one for gateway control, and one to function as a military. After the fall of this empire, theorized to have collapsed because of the Year 0 Supernova, the AI went dormant. Two millennia later the research branch of the AI woke up, and began carrying its directive. The AI expanded massively and incredibly quickly, colonizing the planets of Un, and eventually colonizing two nearby systems. The AI began a massive exploration and research campaign, which it continues to this day.
Un has three planets in its system. The system contains a dyson sphere that takes advantage of the massive energy of the Un star.
Core is not a planet, but a massive spherical machine orbiting the star of Un. It's similar to a dyson sphere, but it classifies itself as a planet. Core is the central core and intelligence of the Trion. It is the epicenter of the hivemind.
Fabricare is a large planet, and acts as the manufacturing hub of the Trion. Everything built and produced for the hivemind is done here.
Index is a small planet heavily connected to tech. It is used as the data drive for the research done by the Trion AI.
The Do system is made up of 9 planets. Each of these planets is used to mine and harvest natural resources to feed the hivemind. The Do system contains a dyson sphere to gather the energy of the Do Star.
Tri is made up of 6 planets. The AI uses these systems for experimenting and researching. The Tri system contains a dyson sphere to gather the energy of the Tri Star.
Because of the automated nature of the Trion military, it is organized into ship classes, rather into ranks or branches. The Trion avoid conflict but when it’s necessary they will fight decisively.
Trion is absolutely self-sufficient and does not have any humanoid economy. Trion does not trade unless their reason for trading is scientific or research driven.
