D'Naevium is a temperate planet in the , home to the Ror Units, and the bureaucratic capital of the Confederacy of Borealis. This planet has one of the most unique biologies in the universe, with about 45% of all species being composed of nanomachines, and over 67% having some form of nanomachines inside of them, more here.
D'Naevium is the bureaucratic capital of the CoB, a large union of sixty galaxies. Large numbers of
This planet is home to a unique form of life called "Synthcaryotes" and "Eu-Synthcaryotes." The former are lifeforms composed out of nano machines which have evolved to behave like life, while the latter are normal forms of life that have incorporated the aforementioned nano machines into their biology to form a symbiotic relationship (essentially phagocytosis but with nano machines).
About 4.5 Billion years ago, it is theorized that an advanced civilization lived on the planet D'Naevium. This theory is supported by very ancient shards of plastic found on the largest moon of D'Naevium, a thin layer of plastic 2 micrometers thick over most of the planet, and some unusually pure chunks of metal orbiting the planet that may have once been satellites.
This civilization was advanced enough to have developed some sort of self-replicating nanotechnology. Unfortunately for them, this technology ended up consuming all the pure metal on the surface of the planet.
The nano machines ended up covering over fifty percent of the surface of the planet, filled the lungs and gills of most species of animals, destroyed all technology, and crowded out bacteria and other micro-organisms. This caused a mass-extinction event of epic proportions. Not only was technology destroyed, but thousands of nuclear power plants melted down. Since they already coated most of the surface, this only made things worse. Eventually, almost all life on the planet besides anaerobic bacteria was destroyed.
The nano machines were 4 micrometers across, making them about half as large as a human red blood cell. They were covered in cillia-like hair which could propel the nanobot through water or, if need be, drag them across dry ground.
The ro machines were theorized to have miniature thermo-electric generators, causing them to seek out heat sources so they could have a steady source of power.
They had a limited self-repair system, but could not maintain themselves forever. When it died, a nearby nano-machine would usually harvest its material and use it to reproduce, as there was only so much pure metal around for them to reproduce with.
Each nano-machine had a very simple memory system. In this system was the script used to control the organism. Like biological genetic code, this script could change over time, allowing for a mutation. This script mostly contained layout and behavioral instructions.
The nano machine population fell to about ten percent of what it was at first due to the lack of available metal. What little biological life remained would usually ignore the nano machines as they had no nutrients a biological organism could use.
Their scripts were intentionally designed to be stable, so it took them over a billion years to finally start mutating. These mutations eventually added up, resulting in a new "species." These machines still needed electricity, but they managed to incorporate a form of sugar fuel cells to harvest energy. This allowed them to become predatory to the bacteria that remained on the planet.
Every nanobot began to utilize elements like silicon and aluminum which were far more common in the crust of D'Naevium. Some even adapted to use insoluble crystals as their main body. A stunning array of nano-machines formed. Shells, drill-like appendages for hunting, creating small bursts of electricity to hunt, propellers to move, creating threads like web to capture nutrients, and dozens of other strategies used to survive. Still, most found themselves congregating around hydro-thermal vents to gather heat.
Around 1.5 billion years ago, they developed miniature solar panels to take advantage of the bright sun of D'Naevium. There were species that concentrated light to create heat for their thermo-electric generators, others used the light to create sugars, and others used the light as a "forge" to better harvest metals they needed to grow.
About 2 billion years ago, the first Eu-Synthcaryotic organisms emerged on D'Naevium. These organisms absorbed some of the solar panel bearing nano machines, allowing for a unique form of photosynthesis called Electrophotosynthesis, turning light into electricity and then into sugars.
Multicellular Life Origin
Eventually, multicellular life emerged on the planet. It is theorized that the first multicellular lifeforms were biological, pressuring the nano machines into becoming "multicellular" as well. This happened 1 Billion years ago.
The nano machines began to group together, forming colonies that eventually became less like colonies, and more like organisms. The machines on the outside of the colony would act as defensive structures, while those on the inside could handle energy production and reproduction. Over time, a battery system evolved in most organisms.
The nano machines in the colonies became so specialized that they were unable to live on their own, officially making them into true multicellular life about 900 Million years ago.
New Means of Energy Production
There were millions of these "organisms" scattered across the seafloor, floating near the top of the water, or swimming through the sea looking for food. Some of the organisms evolved electric generator systems that took advantage of the constant flow of water from the hydro-thermal vents, others took advantage of the tides, and others used currents. They developed flaps and rudders that would spin with the water
These hydroelectric organisms developed large fans to gather the "single-celled" nano machines as well as the eukaryotes so that it could have the materials to rebuild and reproduce.
Others developed a unique way of reproducing. These nano machines essentially became viruses. With some species evolving to infect biological bacteria, others the Eukaryotes, and others infected the nano machines. The nano machines that infected the bacteria, due to the lack of metal present in bacteria, started using proteins rather than metal, greatly differentiating them from the rest of the nano machines.
Colonizing the Land
425 Million years ago, biological life began to live on land, the first plants emerged on land (the regular photosynthetic and Electrophotosnthetic varieties). Some plants made entirely of the nano machines appeared on land as well. Eventually, some of the multicellular nano machines started to live on land. They came to the land about the same time as the biological life did.
The Emergence of the Ror Units
With time, the nano machines began to become much more diverse and intelligent. Some developed a form of flight very similar to fixed-wing aircraft. These organisms had an electric motor move a propeller causing flight
Organisms similar to wind turbines dotted the landscape, they had a firm root system that absorbed essential nutrients, all while gathering energy from the wind. Massive arrays of solar panels covered vast swaths of land. Larger organisms would consume the panels, even biological life evolved a way to absorb some of the energy the panels provided.
150,000 years ago, a species of the nanobot organisms became self-aware. This species went on to become the dominant race of the Intendancy known as the Ror Units.
