Tsenkutli* is a megastructure of white marble and black obsidian steel, built as a real-estate development as a palace for the 3457th son of a galactic empress. He got himself kidnapped, and then incinerated in nuclear fire along with his captors, as an example for other would-be kidnappers. The goblins and star children are the descendants of indentured workers left here for it was too expensive to evacuate or kill them.
It sits decaying between two expanses, the first being the graveyard of stars, a vast desert of rust and the iron cores of stars pocket it. The red dukes and the priests of the silver thread reign over isolated strongholds built into the fresher steel cores, churning out masses of machinery in exchange for a continuous supply of food, water, silver and fuel. The true masters of this realm, if any may lay claim to it, are the reagents, who fight amongst themselves in the vast networks of tunnels deep under the ground with legions of biomechanical monstrosities, hoarding the remains of the empire that left them to die.
The second expanse is the deep, it holds no masters save the maggots, infant gods possessing near infinite power and idiocy. The remains of would be planetary conquerors pepper the ocean, their grossly mangled and mutated bodies impaled upon hundreds of crystalline spikes. They are foremost amongst carrion gods.
The ocean is occupied by teeming multitudes of organisms, feeding off the cursed blood of the corpses. Huge ships of cast steel plie these oceans, powered by nuclear furnaces, organic sails, fins, or far more... eldritch means.
Humans: humans are evolved abominations, even before their encounter with ———, they were 4 dimensional evolved abominations with strange souls. After the mangling of their souls, they are now viewed with either curiosity or contempt, even by their accidental god, Yahweh. You as a human already know the basics, so I shall not go over them. As a result of the mangling of their souls, after meeting -------, emperor of Tsenkuli, demon of words, souls and ------, they have gained immortality.
Vermin:
Vermin, the second most populous species at just under 30% of the population. These have four abilities, first, they never forget anything until their body dies, their conical brains expanding as they age, eventually giving them a sort of horn.
Second, they have prodigious eyesight, as they can change the characteristics of their eyes at will, though complete transformation takes around a week. They can use this to blend in with the population they possess, or adapt to their environment.
third: When they are wounded, or simply whenever they decide to have a change of body, they may shed their eyes, body, and memory cortex. They will then be implanted into another organism's skull cavity, by slipping through the eye and replacing the brain, the creature possessed is usually non-sentient, and always a warm-blooded animal originating from earth.
Star children:
The star children, least populous of the races, at a little over 3% of the population. They can incorporate any organ into their body, and wear elaborate pelts of feathers or scales, their faces lined with dozens of eyes. They naturally live to around 75 years old naturally, though some individuals are millennia old due to their mastery of biotech. They are interdimensionally persecuted due to their ability to produce many compounds needed for biotechnical or alchemical products in their bodies. They possess six limbs, a pair of upper arms that resemble human arms quite closely, save for the extra digits on their fingers and freakishly long thumbs. A pair of lower arms roughly three times the girth of the upper arms, with extremely thick bones and skin upon the hands, used for walking and climbing. These arms are wide set, allowing greater range of motion and rotation while hanging onto things. A pair of hind legs, much stronger, and easily able to support their weight, though a little shorter. They can stand on these back legs in order to free up their second pair of arms, though they are barely able to move when this occurs. A tripod stance is more common, as it allows stability and leverage, even if it does make them able to move. (edited)
Here they are safe, and elsewhere they are watched over by their gods, two stellar demons who adopted them after their creator abandoned them, by committing divine suicide.
In general, technology sits at around the 19 and very early 20th century for these species, with much more advanced biotechnology,
*Tsenkutli the megastructure is named after Tsenkutli the empire, which is named after Tsenkulti the city, which is named after Tsenkutli the river. The current capital of the empire, wherever it may be, is always called Tsenkulti.
