Fucktoy
Fucktoy "Biology"
Almost all Fucktoys are universally fully inorganic. While there are exceptions they are rare. Some organic parts are put on some fucktoys though. Fucktoys are machines that are constructs.
Just because they do not have biological parts does not mean they do not have analogues to biology. Most notably, is their soul crystal. This is effectively their brain, though it is not necessarily stored within the head. In most races, the brain is the interface between biology and the soul; the soul crystal is the interface between engineering and the soul.
Soul crystals: Are the product of a process which liquefies and boils off a creature's soul, condensing the vapors into a more pure and distilled liquid that is then chilled to the point of forming natural crystals. This is part of why creatures usually have varying degrees of memory loss when converted, because the brain itself is only vaguely part of the process, and why the deeper, more significant memories to a person have to be deliberately reprogrammed. Without deliberate effort, the soul remembers what is important to it, and thus the new toy remembers those things as well.
Now you may be asking If the soul crystal is the brain, what about other parts of the body? The answer is that any other aspect of their construction is variable. Not all fucktoys need blood or a blood analogue, most don't require any sort of digestive tract or lungs, though occasionally parts that model those features still exist for some purpose or another. The majority of the body of a fucktoy is created to fulfill the purpose of the toy, be that replicating their previous powers, or creating new effects. It takes a lot of engineering to create or sorcerer powers, or even to create the kinds of dynamic forces and powers required for higher level fighters. And, additionally, most fucktoy designs also care about the first part of the name, the fuck.
Fucktoys almost always have some level of physical design relating to sex. Whether it's simply segmented finger joints that can extend to reach deeper inside someone than they ought to be capable of, or a ThunderCock 3000™, there are very few fucktoys with no design consideration about sex at all. But there are some. The real secret is that despite their name, they are not created solely for sex, and have such a massive variety in chassis and modules that they can be used for nearly everything. What makes a fucktoy a fucktoy is the soul crystal, that is their one unique and consistent feature.
The Toymaker
The origins of the Toymaker are shrouded in the secrets of a bygone age, one of the few questions that the Toymaker themselves won't answer for any cost. It's not even clear if it's something that's known to any but their collective consciousness, but if the information is out there, then it certainly isn't spreading. Whatever their origins, the Toymaker is very firmly established in their own corner of Paradisium, where visits are encouraged, and permanent stays are welcomed but never forced.
The Toymaker is the region that they have claimed, more so than any other creature in Paradisium. They are a mechanical superorganism that has spread and spread and yet settled comfortably on their current borders, not at all out of a desire to avoid angering other inhabitants so much as a lack of need; they have become so entrenched in the firmament of Paradisium that they can expand inwards if they so choose, there's no point to expansion anymore.
There are whispers of a time when the Toymaker was... less concerned with willing test subjects. Where Fucktoys were called Dolls, and said dolls were uncanny predators always hunting more to convert. The Toymaker is very firm in their explanation of the matter; a wave of temporal magic washed out of one of their less-contained experiments, and convinced a number of Paradisium's inhabitants of an alternate reality. Whether that's true or not, well, that's up to the reader to decide.
As it stands now though, the Toymaker has no need for forced conversion. There are enough souls in Paradisium willing to give their selves away to the collective array of soul crystals that composes the Toymaker's mind. The Toymaker concerns themselves with experimentation and research now, for apparently no ends aside from advancing the state of knowledge itself. They are happy to make deals, or take visitors, or even trade, because it takes such a small fragment of their collective concentration to speak with others that they never need leave their experiments unattended. But not all experiments are safe, attended or not, and they find annoyingly larger fractions of their consciousness embroiled in the politics of Metropolis City, if only to avoid unwise incursions into their land.
