Im bored so here more species first drafts
warning:: this is literally just a first draft so shit will be changed later on probably
While there's only one recorded case of successful doll life (Liu), it doesn't mean there isn't hundreds of notes about their creation.
Dolls are being that look like regular people minus their stitched up bodies. They can be female, male, both or sexless depending on what sex their creator wanted them to be.
Dolls only have four (well two to be more precise) internal organs- a brain, a heart, skeleton, and most importantly- a soul. Without these these aspects, Dolls aren't capable of living.
Dolls do not have blood, and instead have some form of black or grey blood-like goop to replace it. Dolls also have a more black hole esque, strong version of this goop to replace their organs and muscle.
A dolls skeleton is a hardened version of this goop, and it is incredibly durable and strong and can regenerate overtime as well as there's a cell left.
Due to the fact dolls don't have organs such as lungs, stomachs, etc, they do not need to eat or excrete or breath. Eating or breathing is optional. Excreting is different for dolls due to the fact that the black hole esque goop inside them just devours and remakes the food or whatever that entered their body to become new goop.
A doll's heart and brain is basically like a person's, but much more durable and much harder to destroy due to the fact the organs can regenerate over time as long as there's a cell left of the organ left.
A doll's body is like a person's but made with many different magical materials (mostly to ensure it can hold the goop in, regenerate, look like a person, etc). unlike a normal person it can easily regenerate as long as there is a cell left to regenerate from, and parts of the body can be sewn back onto the body but both of these processes are incredibly painful.
Dolls can only become alive once they have some form of a soul, otherwise they are a empty shell of a body. It is currently unknown how to remove a doll's soul from its body- not even reapers know how to. If a doll's body is COMPLETELY DESTROYED, the soul can easily just go on and roam the world forever until it gets a new host unless the soul gets intervened with.
Dolls, due to how magically high their bodies are, are capable of many unique or powerful magic abilities, and can easily master voodoo.
Dolls are hairless minus facial hair (eg eyebrows) and regular head hair. They do not have fingerprints, nor do they have body odour (they still regularly shower though). Having nipples or belly buttons are optional if their creator wants to add them.
It is currently completely unknown how to kill a doll, and they are currently stuck in the "true immortal" category.
Dolls, unless made to be lobotomised/dependent on their creators/etc, are capable of free will, personalities, hobbies, interests, etc. And yes, they still need sleep.
Dolls age much differently from regular species, both mentally and physically.
all dolls or the vast majority of them are able to turn into a literal doll form of themselves.
There is only one successful attempt of a doll in this world right now, which is Liu aka Leviticus, who was created by the sin of treachery, Askarath.
