100th Millennium Wiki

D'Naevium is a temperate planet located in Via Aylathiya. It is the current capital of the Alkan Intendancy as well as a chivalric order known as the Alkan Order. As the most populous planet of the Intendancy, D'Naevium is one of its most valuable worlds within the Intendancy. It is the home world to the Ror Units, a species made up of nanomachines in lieu of actual cells.


As the capital of a knightly order, especially one with the title of "Prime Intendant," there is a large government apparatus present on the planet. Local affairs are handled directly by the security agencies overseeing the protection of the knights. While most planets in the Intendancy have some level of self-governance, D'Naevium is ruled entirely by the highest echelons of government.

Most of the inhabitants of the planet live in orbit around it on large rings orbiting the equator. This was done to more easily govern the populace as the fully artificial rings proved to separate the potentially dangerous inhabitants from the government. A small number of citizens live on the surface of the planet; something that is incredibly expensive. These people are usually ludicrously wealthy members of the merchant class that want to easily interact with the Alkan Order in person.

Unique Life

This planet is home to a unique form of life classified as "syntharyotic organisms." These organisms are made up of nanites in lieu of cells. These units are called nanites to distinguish them from fully artificial 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 nanomachines 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 (this is known due to several artificial isotopes remaining on the surface of the planet). Since they already coated most of the surface, this only made things worse. Eventually, all life on the planet was destroyed.

There are only a handful of simple fossils from before the mass extinction event. These mostly include traditional bacteria and other single-celled organisms.

Nanomachine Layout

The original nanomachines were about 4 micrometers across. They were covered in cillia-like hair which could propel the nanomachine through water or, if need be, drag them across dry ground. The 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 nanomachine 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 nanomachine population fell to about ten percent of what it was at first due to the lack of available metal. The corpses of dead animals soon decayed away. Once the decomposers ran out of material to decompose, a mass die-off occurred. Biological bacteria remained alive for another two billion years before being out-competed by the evolving nanomachines. On land, the lack of material and the difficulty of movement caused most nanomachines to move into the ocean or oxidize rapidly.

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 nanomachine 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 nanomachines 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 emerged to survive. 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. Around this point, scientists stop classifying them as "nanomachines" and, instead, call them "nanites."

Multicellular Life Origin

Eventually, "multicellular" life emerged on the planet. It is theorized that the first multicellular lifeforms were small collections of photosynthesizers that could better concentrate light onto solar panels. Once the component nanites began to specialize, they became more advanced. Eventually, predators would form due to pressure the photosynthesizers put onto them. These predators filtered large amounts of water through themselves to gather smaller organisms to absorb their nutrients.

The first macroscopic organisms were small colonies of filter-feeders on the sea floor. They eventually developed a sort of "turbine" that would generate energy using the current, allowing them to pump more water towards themselves. These turbines served as the basis for propeller-based organisms that would later evolve. The first macroscopic free-swimming organisms used propellers to move through the water.

Others developed a unique way of reproducing. These nanites essentially became viruses. They found a way to infect large organisms to cause them to create copies of themselves. They often injected their code into the memories of their host organisms, although they would often not kill their hosts. In fact, viruses that killed hosts were incredibly rare. The reason is that hijacking the nanite and using it to continually manufacture new units is far more useful than killing the host before it could produce as many copies.
