The background of this character might be a bit thick and extreme but I rather like it because it has a lot of hooks for future story development.
Edit: I wasn't comfortable with the background so I altered it a bit.
Name: Amalia
Species: "tailed fae", see backstory for details
Sex: Herm (fth modded)
Gender: woman
Role: scout, informant
Appearance: at just above one and a half meters (that's around 5ft in freedom units), Amalia is rather petite. Her smooth, lilac skin and purple eyes give her an exotic appearance, with long eyelashes, thick eyebrows, the flat, slightly wide nose and a small mouth with very narrow lips only serving to underline her doll like features. Her head is sparsely populated with very thick strands of hair, which she usually keeps braided tightly into a single braid. She has the characteristic pointy ears of her race.
She has well defined, but not too obtrusive, perky breasts and a slender build. Her feet have an opposable toe and can be used for grabbing. A prehensile tail almost as long as she is tall completes her build. In addition to her natural vagina, she also has a modded penis, which has a length of roughly 9 cm when fully erect. Since it was never properly attached to the urinal tract, it is very high maintenance and needs constant care to prevent infections, which is why Amalia is debating whether she should "fix the piping" or just get rid of it altogether.
Personality: bubbly, happy, eager to please, very eager, to be exact... yeah, she is a nymphomaniac. Not the sharpest knife in the drawer but not dumb either. Her decisions usually don't have bad outcomes because she didn't think them through but rather because her priorities are all kinds of backwards and sideways.
Abilities: full 3d mobility in arboreal or similar environments, fast twitch reactions and high grip strength on all five limbs are her only physical traits, courtesy of her ancestor's arboreal lifestyle. She has no combat training at all and is actually rather weak and can not carry all that much. Her actual strength lies in socialising, seduction and information gathering through social interactions.
As for her intelligence, when it comes to performing complex tasks, she is actually on the dim side, but in terms of communicating and emotional intelligence, she is a genius... of sorts... sometimes.
Racial Background: there exists a quiet and unremarkable planet without any ancient ruins or abundant mineral resources. In the treetops of the vast forests that span the planet, ferocious battles are fought. Explorers who came to the planet looked at the tiny species zipping through the air and could only liken them to fairies. Smooth skin of all kinds of bright colors, pointed ears and long, prehensile tails... the name "tailed fae" soon caught on with people who had only seen them in pictures. The original explorers would always refer to them as tree devils, given how ruthlessly they were killing one another up in the treetops... but there was another arrival of spacefarers who had a name all of their own for the natives: "tailed fuckdoll."
The tailed fae had caught the interest of the adult entertainment world and soon they were abducted by the hundreds and preliminary experiments were promising. Mental conditioning drugs and gene modding worked all too well. More than a century later, tailed fae can be found on any major world of the galaxy.
Personal Background:
It is estimated that for every tailed fae that has been granted full citizen rights, there are fifteen that live in one form of slavery or another. The galaxy isn't a kind place to those that were forcibly uplifted. Amalia is one of those on the bottom. Born in a laboratory in an unspecified location, she spent most of her early days lying around in a daze, covered in her own excrement. One day, though, she caught the eyes of Ronald Carver, owner of multiple adult entertainment complexes all over the galaxy, who was in the middle of buying fresh girls in bulk, when he encountered what he believed to be a diamond in the rough. But that diamond needed to be polished.
Working for Ronald actually helped Amalia a lot. She was taught to speak, learned about the world, got a supply of effective and highly addictive libido enhancers and had her personality rewritten from the ground up to something that would help her rake in money. And she did. Over 14 years, she got to entertain all sorts of high end customers.
Ultimately, all things have to come to an end. When her establishment was raided by a rival gang, she took the opportunity and booked it. She still has some of her connection to her old patrons which might be leveraged to get a space ship at a discount... though there might be some risks involved since Ronald Carver is still looking for his most prized possession.
Sexuality: To put it into one word: yes. She was literally (re)built for this, but she has some rather particular preferences. Though any sex is welcome, she has a preference for very long sex that has a slow and elaborate buildup towards an overwhelming orgasm. Amalia learned that sex is more than the sum of its parts since no amount of masturbation both on her own and with the help of all kinds of devices could replicate the effect of bonding with another... and it wasn't for a lack of trying. So whether it is slow and cuddly sex, that slowly builds up towards the climax or prostate play with cock and ball tease, Amalia has learned that a quickie does hardly anything to scratch her itches and the buildup is far more meaningful than the climax. A good session for her is anything upwards of two hours. As for the particulars, whatever is your fetish, she is probably down for it, but she simply doesn't get some of the fetishes that are driven by taboo... like scat, for example. She neither finds it revolting nor arousing, it simply doesnt invoke any kind of reaction, probably because much of her early life was spent under rather unhygienic conditions.
Goals, outlook and philosophy: she isn't interested in uncovering the fate of the progenitors, mostly because in her mind, the answer is already clear and rather boring. Since their tech was rather advanced, they must have had some amazing drugs. Probably spent too much time fucking and doing drugs as their cities fell into disrepair. Rather, her goals are rather materialistic: get loads of money, become a big badass bitch that nobody dares push around anymore, get even more money to start modding her body so she can have even more awesome sex, get even more money, probably to blow it all on drugs and hookers... but above all, get lots and lots of money.
