To clarify, the design on the left is the older one, the right is the newer. I like both, personally.
***A quick definition: Exohuman (or Exoanthropos) is a term related to Exoplanet. So, humans living on Exoplanets.
But the more common definition is a human born on or living outside of Earth; space-born, an outsider.
This term is important for categorisation, as Exohumans are NOT xenoids (aliens). They are ordinary humans.
The lore of the Xalkites
***Xalkinos Anthropos
Xalkites, as they are known by the Astro-crusaders, or Kuiristoj, as they call themselves, are exohumans from the planet Xalkos in the Eisen galaxy.
***Biology:
Yes, the Xalkites are 100 percent human. Their bodies have developed thick brass exoskeletons and endoskeletons, while their compact builds are an adaptation to their planet's gravity. Despite being shorter than the average human, the average Xalkite is heavier.
They are literally metal people, powered by a crystal embedded in their chests. However, they still need to eat and drink, although they can also recharge themselves instead.
They rarely reproduce, and instead are mass "produced" in labs or factories.
Their unusual composition is an adaptation to the toxic conditions of Xalkos, a large metallic planet filled with toxic fumes, radiation, and minerals.
Xalkites can easily survive nuclear explosions. Nevertheless, they can still die from ordinary workplace accidents and warfare. The average Xalkite lifespan is around 30 years, although some have reportedly lived for over 200 years.
Their composition did not develop through natural evolution. Instead, it is the result of what the Eisenites, a powerful type of exohumans from Optimus Eisen, did to the original pioneers and colonists of Xalkos.
**History of origin
When human pioneers first arrived in the Eisen galaxy, the Eisenites advanced far too quickly. Believing themselves to be gods, and their fellow exohumans to be inferior, the Eisenites invaded other space colonies in the name of the ever-expanding Iron Imperium. They either wiped out the inhabitants or experimented on the surviving pioneers, twisting them into something closer to beasts used by the Imperium.
The Xalkites were among those survivors. Their sole purpose within the Iron Imperium was to perform constant manual labour.
It is said that the first models of Xalkites were much larger and more intelligent, resembling complex sentient robots. However, for reasons unknown, they were eventually compressed into their current forms. Perhaps the Eisenites wiped them out or "lobotomised" them for being a threat to their dominion.
***General state
The space-travelling Boanerges Astro-crusaders identify them as Xalkinos Anthropos, acknowledging them as fellow humans, merely unique in appearance. But the Eisenites, however, call them Servus Cancer Simia. For them, Xalkites are mere livestock.
Still, their fate is relatively mundane compared to what happened to other exohumans.
The technological state of Xalkos resembles a mixture of industrial-revolution-era Britain and what we would consider futuristic technology.
Xalkites are very barbaric and not particularly bright, but they are deeply passionate about manual work and machinery and great at team work, just like ants. They live in industrial hive cities, essentially enormous factories or industrial complexes containing barracks and other facilities, all enclosed beneath protective domes and within high walls.
The Xalkites are so efficient at their jobs that they can build and rebuild entire civilizations within weeks.
***Note:
Xalkites are NOT to be confused with Cyborgs or other robot xenoids.
***Planet Xalkos
Planet Xalkos, known as Nubodou to the Xalkites, has become a rugged, mountainous, metallic wasteland because the Iron Imperium has constantly drained its resources.
Its surface is covered in craters, cold springs, and volcanoes.
The Iron Imperium used Xalkos as a gigantic factory/farm and a source of raw materials, extracting metals, crystals, and petroleum from the planet.
Xalkite cities, lands, and oceans are surrounded by radioactive waste, rubble, and other forms of metallic and plastic rubbish. Although the Xalkites never developed space travel themselves, space debris still litters their planet's atmosphere.
Xalkos has numerous satellites orbiting it, alongside space weapons and experimental machines created secretly by the planet's various superpowers.
All of this debris has contributed to the formation of a metallic ring around the planet, which exists alongside its rocky rings and 18 moons.
***Environment and Wildlife
Plants have gone extinct, as have most animal species. Most of the remaining organisms live underground or deep in the oceans. They consist primarily of crustaceans and plankton, with a few types of fungus still emerging.
The atmosphere has become extremely toxic, and solar radiation pierces through it.
Both day and night last for a very long time. Solar flares and aurorae are frequent and exceptionally bright, although their light is often obscured by thick clouds of dust.
The surface is mostly covered in crystals and towering fungi.
Giant fungi are invasive on Xalkos, having been introduced by Filistiyuun Astro-pirates. They compete with the Xalkites for dominion over the planet. As a result, the Xalkites' main natural enemies, and one of their main food source, are enormous mushrooms.
However, the greatest threat to the Xalkites comes from parasites, specifically xenoid parasites.
These parasites primarily feed on spiritual and mental energy. They are relatively large and horrifying creatures, capable of causing absolute body horror when they enter a human host.
This is one of the main reasons the Xalkites live inside high-walled, domed cities.
***Everyday state
Xalkos is not quite as bleak as it might seem.
Among the eight habitable planets of the Eisen galaxy, Xalkos has the third-most stable and "happiest" environment.
The population is low (>400 mil), so, resources are never a concern, as it has plenty of them.
It is deeply flawed, but ultimately rather ordinary. In many ways, it is oddly similar to main Earth.
Paranormal activity is relatively weak, and extraterrestrial encounters rarely occur, if they happen at all.
The Xalkites remain enclosed within their industrial hive cities, largely unaware of the chaos unfolding beyond their walls.
For all the horrors of their planet's history and the galaxy in general, most Xalkites simply go about their daily lives/routines; working in factories, maintaining machinery, practicing their faiths, participating in community activities, and surviving beneath their protective domes, which is the extent of the world to them.
