Fahd Backstory (original)

Fahd, and as far as the paper-trail is concern he's always been Fahd Zaki and never his Tajaran birth-name, started off as the child of a 'manager' of a group of archeologists - in the Habitable belt, of course; That being the best place to find ruins that aren't either in the middle of a glacier or protected by rather archeologist-unfriendly Keepers.
To be clear, his father was not an archeologist - it'd be more accurate to say he acted as a people-competent middle-man between the scientists (who don't know how to talk to normal people - the Dunning-Krueger effect (which Tajaran don't know about, unless they're particularly versed in human books on psychology, but which still applies to more or less all sapient races) doesn't just say fools think that they are wise, it also says that if you're an expert on the nuances of anthropology, you tend to assume everyone else is too) and whoever they need to talk to (people to fund expeditions/studies (probably NT, but there's quite probably one or more individual people who need to be convinced that the results are worth the funding), 'peasants' whose back-yards they need to dig up, and so on, who don't generally know how to talk to scientists).
This still means he held more 'power' and responsibility than any given scientist under him, since a bad manager can cause far more damage than a bad scientist, so 'Papa Zaki' (not his real name, of course) was decidedly 'noble', if perhaps not very far up the ladder.

Noble by association, Fahd gets a fairly decent start at his education.
At first, it's more reliant on what his father can get him (which might be a very simple 'whatever the official school teaches', or it might be more complicated), but generally speaking it ends up being a below-human general education (so, pretty good by Tajaran standards) the details of which don't leave much impact beyond possibly leaving him more or less behind on specific subjects when he continues the education later.
When he's old enough to be able to tell what he's got talents in, he starts pushing for anything he thinks will help him reverse-engineer alien tech, so mainly things like physics (to understand the basis for how things work) and whatever engineering he can get - at first not even all that intentionally, he just finds it more interesting to study, but over time it becomes a 'dream'.
Obviously, the 'alien tech' he wants to reverse-engineer is that of the other sapient races, especially humans - even more obviously, what he tells anyone who asks, Tajaran or not, is instead that it's the ancient tech archeologists sometimes dig up.

If he had been human, with a human's tendency towards violence and rebellion, he'd probably have joined up with some 'Secession Party' and started protesting.
But he's not, he's a Tajaran, with Tajaran values, who likes the sound of a few of the ice-nomads' beliefs.
So, he doesn't want to take the planet for the Tajaran: He wants to 'share' it, but the humans seem reluctant to share their stuff.
If they won't help 'uplift' them to the modern age for fear they'll lose their cheap workforce, they'll just have to take the initiative.
The humans might lose a bit of profit, but it won't really hurt anyone - they'll just have to accept a higher wage for better-educated workers.
Heck, it's not even really 'humans', it's 'NanoTrasen' - most humans are fine people, but no one likes NT. Not even their best-bud Einstein likes NT. NT's earned their place in the world by being bigger jerks than their competition, and seem intent on keeping that title.

But, even with the lie, there's not that much pay in just being able to understand basic technology.
There's also not that much in the way of ways to get 'certified' for the more serious sciences either, at least not planet-side.
So, it was more or less a foregone conclusion that Fahd'd eventually accept the '30 year contract' that comes with education and so on.
This would be when he got his name too - for all his dreams of subverting the human superiority, he's not that serious a person, so he figured that if the humans were going to call him 'cat', he might as well make that his new name. He wouldn't be the first to get a name more suitable for human tongues, nor the first 'egghead' to enjoy private jokes.
After searching and asking around for a while, likely over the course of a few months while he mulls it over, he finds two pre-common words for cat he feels he can live with: Fahd Zaki - so, that's what he writes down on his application.

Going back a bit, he had a rather nasty accident when he was in the late pre-teens.
Specifically, he was visiting an archeological site in the contexts of getting some 'real world' examples of how the stuff he's learning could be used.
Clumsy as he is, he trips over some tools he hadn't seen, and in the process of trying to catch himself ends up dragging his right arm and left leg along a partially-unearthed ancient sword - it cuts fairly deep too, with most of his weight behind it.
Normally, for a semi-noble like not-yet-Fahd, this would just involve a trip to a medic and some nasty scars as an ache-y reminder of his carelessness.
But, he's not that lucky, and while they of course washed and bound his wounds, an infection still slips through the rudimentary disinfection.
Short version, they manage to save his limbs, but have to carve away a fair amount of muscle in the process - a human doctor with a top-of-the-line set of medical equipment could almost certainly have saved him without problems, and so could top-of-the-line disinfectants and sterile bandages, but even if they'd been able to get those at 'market prices' (which they wouldn't have been) they'd probably have settled for the cheaper options - they're high-middle class by Tajaran standards, not human ones, and couldn't really have foreseen that kinda bad luck.
He gets used to it eventually, even becoming somewhat ambidextrous where he was previously right-handed, and replacing his professionally-made leg-brace with a slightly inferior self-made one.
As for NT, while Fahd's no genius, he's at least good enough that they're willing to provide prosthetic replacements (Fahd's also no idiot, so he's not surprised when the the guy in charge of the 'replacement' is almost as green as he is, and would probably have to pay most people to play victim - it's not exactly pleasant, there's a few delays when the rookie remembers he needs anesthetics and sterile saw-blades, but in the end Fahd gets some shiny new limbs)
By 'current day', he's gotten so used to having the more convenient limbs (stronger, sturdier, and a lot easier to fix) that the two times over the years that he's woken up with a perfectly healthy body he's convinced the first robotics he can to chop them off and give him new prosthetics (again, he's not an idiot, it's almost certain that he was cloned. But everyone talks about how people who learn about being cloned go crazy, so even though he thinks they're exaggerating, he doesn't try to prod too much) - whether the roboticist gets told off for giving free stuff away like that (and/or enabling what's probably considered a less-than-stable habit of Fahd's) is another matter, and not really Fahd's problem.
Just the same limbs, though - there are some downsides, and nowadays it's more about being used to it than anything.

The first year or two's fairly standard, as far as Tajaran joining NT's workforce is concerned.
NT reveals that they didn't intend to give him quite the extravagant education they'd promised, Fahd is entirely unsurprised since it's not like he hasn't heard of marketing and he ends up with pretty much what he expected.
They try to make him work during times he is supposed to have time off for studying, he starts studying during lunch and parts of the limited downtime meant for sleeping and such - just like plenty of other employees before him, quite probably including a lot of humans too.
He's given tedious jobs unsuited to his 'skillset', tending the hydroponics or mining depending on the rest of the crew available, but shrugs and shares some toasts over the years with former HoPs made scapegoats for failures they had nothing to do with, and scientists demoted to janitors for speaking out against NT's practices.
He finds out humans with the same jobs as him get better pay, so Fahd thinks back to his life pre-joining, considers the delicious food and comfy beds, with very flexible hours (as long as you can hide from any over-zealous 'Heads') - heck, there's even free booze, if you can find a friendly barkeep - then looks down at his better-than-real-limbs prosthetics that serve as a reminder about the difference in health-care-quality. If you forget about the occasional overly-strict Head, and look away from how disturbingly similar the station is to the Temple Cities (really, give humans a few decades to perfect AI tech and breed the perfect plant, and they'll become their own Masters, with Keeper-esque station-AIs keeping them to NT's guidelines and self-tending crops feeding them without 'wasted' manpower spent growing or processing the food) then the station's rather close to a Tajaran's dream (which is a bit strange, for a capitalistic company like this)

Eventually he manages to get through the 'certification exams' to get his various qualifications for more interesting jobs.
Sure, he is often still stuck working the gardens or digging through rock to free up the more 'valuable' humans, but sometimes he's actually able to convince them to let him work in 'RnD' or out on the asteroid.
He is quite unqualified for non-anomaly archeology, and has little to no interest in it, but when the higher-ups are moving workers around they don't necessarily take the time to understand the difference between 'This person is qualified to work with ancient tech' and 'This person is qualified to work with ancient ruins' - so, sometimes he's put on a shift and told to gather data on ancient relics. It's largely a coin-toss, in those cases, whether he'll decide he's willing to risk getting in trouble for disobeying orders and doing his own thing until he can get someone to re-assign him, or take it as a 'learning experience' and actually give untrained archeology a shot (breaking a lot of priceless relics in the process, but he's broken far more as a miner without the fancy equipment for finding relics without relying on the distinctive 'crunch' noise they make when you drive a drill through them)
But, artifacts are rare, of limited use, and not what NT's after. (And not what Fahd's after either) So a lot of the time, when they let him use his fancy certifications rather than hand him a pick and tell him to start digging, Fahd's reverse-engineering qualifications are instead put to work in the 'true' Research-and-Development branch of the Science wing. Sure, human scientists probably do a far better job, but he's tried very hard to always have an excuse not have to work in the same area as a human scientist - one part just not being good at the whole 'working with others' thing, and one part not wanting the hit to his ego he'd get if it turned out he really is way worse.
Generally speaking, though, he's generally put on the 'skeleton crews' for shifts and/or stations where it's useful to have cheap labor willing to do multiple jobs, to 'keep the kettle on' for the 'real' workers - heck, when left alone, Fahd's pretty good at getting acceptable results without any trouble, it's when people start trying to order him around that the Tajaran 'We're all in this together, we should share the labor and the spoils both equally' attitude can border on insubordination.

It'd be wrong to say that Fahd's got a criminal attitude, but right to say that he's a criminal.
Mostly, let's call it a mix of 'cultural differences' and Fahd having little to no respect for NT's rules (instead treating them very much at face value of a 'if they catch you, this is the consequence' situation)
For example, NT says that if he gets caught stealing, he gets put in 'time out' for such-and-such a time.
Fahd considers this and decides his time on the shift would be made easier if he had some specific thing he's not permitted to have, and no one's really going to miss it - if it's worth risking the punishment, he doesn't think twice, nor feel bad about it; In his mind, he's not actually doing anything bad, arbitrary punishments are just part of the 'downside' to working for NT.
Eventually, he's inevitably going to get unlucky and get caught - which he has been, several times.
But, he's cheap labor bound to a 30-year contract, made even cheaper when they start fining him for 'stolen' property (which they don't even have to replace, since he couldn't take it off NT-property even if he wanted (what with spending most of his time either on NT-owned central hubs or NT-owned stations)) and supposed lost profit whenever they can pin a Disturbance charge on him.
So, sometimes he's threatened a bit, 'shown who's in charge', maybe even temporarily demoted - then he's put back on the schedule, some other paper-pusher decides it'd look good on their budget if they replace an expensive human expert with a cheap Tajaran, and he's back to status quo without really having learned anything.
Besides, he's pretty good - not great, but there's plenty of lazy or incompetent humans that make any diligent Tajaran look good, even ones like Fahd.

Of course, all of this was 'Somewhere Else' - probably several different 'Else'-wheres.
The last thing to happen before we go into 'present day' is that he's transferred to a faraway station (NSS Hypatia, needless to say) to improve his old station's statistics a bit, and potentially to spread out the Tajaran work-force a bit (his last station, while still having a majority of humans, had more Tajaran than other non-humans combined)
