From the perspective of the outside universe, the planet Hestia experienced a brief solar eclipse only a few standard UCC years ago. From the perspective of those on the surface, thousands of years in darkness passed due a time dilation effect by the interaction between primordial crystals on the planet and moon.
A CYCOL military force that had been landed to harass the human colony was cut off. They developed a method to reproduce without a nodesphere, and their culture changed over the long timespan. Tranq is a distant descendant of the original CYCOL in the planet. Like all CYCOL, its brain is still entirely organic, but it doesn't have a humanoid mechanical body that its distant ancestors had.
Tranq is shown here deep inside the ruins of the human colony, evading the attention of the post-human offshoot species that now haunts the old buildings.
