Description:
A Ecumenopolis, Ferros is covered in a silvery cityscape that encompasses the entire planet surface leaving no visible oceans or mountains. Dark indigo and purple plants have long since grown over the metallic landmass creating a dull violet hue seen from orbit. The twilight zone separating day and night glowing red from the high oxygen content in the atmosphere interacting with the bending sunlight.
Due to the planet's low axial tilt there are no seasonal changes, keeping the weather warm all year round. The poles are an exception to this, where the curvature of the planet keeps the sun set low at the outer edges, and completely absent at the very center, leaving them covered in ice caps.
There are no visible oceans on Ferros, rather all the water coalesce in the underground tunnels and basements, with the minimal minerals resulting in zero salt content in them.
The warmth of the sun collects clouds of water vapor, where they cool down in the night cycle creating torrential rain storms every night.
Origins:
The original builders and inhabitants of the city are shrouded in mystery, with no data on them left behind. In absence of information they became referred to as the precursors, speculated to have disappeared from the world approximately 160 million years ago judging from the fossil records ending past that point.
The term disappear is more apt with there being no physical remains of them, even as fossils. This led to many theories, ranging from the precursors leaving the world willingly to transcending the physical plain. Whatever the reason, it is agreed that after their disappearance life was allowed to flourish on the now depopulated world, the metal streets and spires covered in indigo plants basking in the alien sun while animals evolved to thrive in the artificial landscape.
One discrepancy is the origin of not just the city, but the entire planet of Ferros. Orbiting an F type star, which only holds their stability for 3 billion years, the planet would have to be incredibly young; far too young for the Precursors to have evolved on it naturally. Radiometric dating reveals Ferros is 4.6 Billion years old, over twice the age of the star it is orbiting. The implications being that the planet is not native to the Vitrus system but was somehow moved there, giving credence to the technological prowess the precursors held. This has given doubt if Ferros was even the precursor's home world or just one of many megastructure projects they created on a whim.
Ecology:
The surface of Ferros is covered in a near indestructible metal alloy called Tiemiun rather than dirt and rock, forcing the plants and animals to adapt to this unique and artificial landscape. While Tiemiun is extremely durable and long lasting, small particles of it gradually shed off over the course of millions of years; polluting the waters and bodies of plants and animals. Rather than discarding the metal, the life forms of Ferros have incorporated it into their biology. Growing teeth, scales, claws, mandibles, and skeletons out of the durable material.
The water cycle of Ferros is just as consistent as its temperature. Water vapor rises from the plants during the daytime heat, and rains back down once the temperature cools during night. The rainfall is so intense that most animals seek shelter from it or risk drowning, or being swept by the newly formed rivers down underground. Due to Ferros being leveled, there are no oceans or lakes, rather the water pools down to the underground tunnels and basements, flooding the lower levels.
Steelvine starts its life cycle growing in the underground waters, where they sprout from hard shells and rapidly begin the desperate race to reach the sunlight above ground. Most steelvine die off before they could reach sunlight, where the decomposing plants act as nutrients to give future steelvine a greater chance of success. Once reaching sunlight, steelvine rapidly grow around the tall metal spires, covering the mile high monoliths in indigo leaves. Instead of letting pollen float through the air, the vines let the regular torrential downpour carry their seeds down into the flooded tunnels, completing its life cycle.
Creepmoss is a purple moss that grows on any surface with sufficient sunlight, covering the ground in several inches of the soft spongy material. Other plants have utilized the inane moss as a soft fertile ground to grow their roots in and sap nutrients from, making creepmoss the new essential soil of Ferros. The moss is still too shallow for deep roots, making it insufficient for the development of arboreal life. Small shrubbery and bushes is the maximum size of what could be grown.
Fleshmold is a gray fleshy biomass that grows in the flooded tunnels, preferring the dark and high humidity. Its biology is more akin to cancerous cells, each cell able to live individually and mass replicate till every surface of the tunnels is covered in the biomass, creating an environment known as slime tunnels. Various parasites live on and within the fleshmold, which in turn are preyed upon by predators adapted for the organic environment, making the slime tunnels their own enclosed ecosystem.
Notable Species:
Centiwig’s are twenty-four legged and three foot long (1 meter) arthropods that stalk the narrow pipes and vents of the fallen metropolis in search of prey. Coiling around their catch, they deliver venomous bites with their fangs, which often prove to be lethal without antivenom to treat it. Occasionally they are spotted outside the cramped tunnel network where they become easy prey for a multitude of larger animals.
Standing twelve feet tall (3.6 meters) on long thin legs, Raintelopes are herbivores that feed off the easily obtainable Steelvine that grows off the sides of buildings. Instead of seeking shelter from the rain like most animals, Raintelopes wade confidently through the floods on their long limbs. The fur of older Raintelopes is slightly violet from moss growing in it after years of being rained on. Falidae would often ride Raintelopes by attaching reins to their antlers so they could traverse the dangerous surface.
Rainbow Lizard’s are two feet long (0.6 meters) and similarly to Centiwigs hunt in pipes and vents. Their bioluminescent scales display a wide range of colors that has given them their name, making it easier for them to spot mates in the dark interiors they reside in. However, their heads are pitch black because it is not made of scales but a durable natural armor, making them extra protected as they delve headfirst through narrow passages on the hunt. Various Falidae tribes have managed to domesticate Rainbow Lizards, using them as the human equivalent to hunting dogs.
Leech Grass blurs the line between plant and animal. Growing from a spore inside the Creepmoss, the warm blooded Leech spends its juvenile stage feeding off the nutrients of the moss before it fully matures. Fully matured Leech Grass stands fully erect at eight to fourteen inches tall and embedded into the Creepmoss via thin roots that are made of its digestive system. They are black to consume as much photosynthesis as possible, but this only staves their hunger until they get access to their main food source. On the tip of their heads is a small white eye that can vaguely detect shapes and movement, where the leech then instinctively moves toward to bite into and suck its blood. They release a paralyzing toxin in their bite to immobilize their prey, which has a minor effect on larger animals. However, Leech Grass grows in clusters making their toxins build up through multiple bites, often overwhelming their prey which they proceed to suck dry. Their waste then travels down their roots to fertilize the Creepmoss they are growing in, maintaining their home. To reproduce, Leech Grass shoots their spores into the air, which would intermingle with the spores of other Leech Grass. Fully fertilized spores land into the Creepmoss and a juvenile sprouts from it.
Building nests in the spires that dot the planet, Skull Vultures are the winged predators of Ferros. Six feet tall (2 meters) and a wingspan of fourteen feet (4 meters) long, the black feathered bird kills its prey by bashing them to death with its blunt beak. Their skulls reinforced to withstand their repeated bashings everyday.
Wandering Snail’s live inside a shell for protection, using two arms to crawl along the ground in search of rotting plant matter to eat.
Skavenger’s are four inch long arthropods that eat decaying plants and animals by regurgitating acid onto them to help break it down into a slurry they can more easily consume.
Steel Ox are so named for the use of micro particles of Tiemium found in plants and water to incorporate into their scales to create a near impenetrable armor. The thirty foot long (9 meter) behemoths graze the ground for any shrubs and plants growing from the Creepmoss, roaming in herds.
The natural predators of Steel Ox’s are the Diamond Tooth’s. Their teeth incorporate Tiemium making them durable enough to pierce the scales of Steel Ox’s. Standing on their hind legs at twelve feet tall (3.6 meters) Diamond Tooth were persistence hunters, able to keep a steady run of thirty-five miles per hour (56 kph) for several hours.
The slime tunnels are notoriously dangerous because of the slyve worms that inhabit it; thirteen feet long (4 meters) they slide through the holes they borrowed through the Fleshmold to ambush and consume anything that wanders into their territory. Slyve worms cannibalize each other on sight. They reproduce by leaving behind their unfertilized eggs in a mucus trail as they travel, which would be picked up by other worms to be fertilized.
