To work on a sort of timeline, I'll use B.S.U (Before Steven Universe) as a measurement of time, since that's how the timeline on the wikia works for me to get an idea on when a set of events happen. Since Before Steven Universe marks the timeline as before Canon begins (I.e. the show), I'll use that.
5,500 B.S.U.
Yellow Diamond's Ship
With a satisfied expression of her 'magnum opus' so to speak having been completed, Yellow Diamond continued to carry her personally made gem with her before finally setting her Citrine gem down on her nearby console table, its size vastly dwarfing her Citrine gem's stature; with her project finished, Yellow could return back to homeworld and continue working on her incoming reports of various colonies under her control, while periodically seeing how well Pink was doing in controlling her own colony.
As Yellow sat down in her chair within the bridge of her ship, she noted that her new gem she had placed beside her on the nearby console table was earning curious gazes by the Nephrites within her Ship's Bridge; Oh sure, her Nephrites were diligently working on getting the ship into the air, and eventually ready for take off, but occasionally Yellow would catch a few or so gems throw curious looks at the new Citrine gem beside her. She couldn't fault the curiosity, but she would not accept any slacking off or distractions.
So far, none of the gems were slacking off, and the curious glances were just that, thus Yellow allowed the slight curiosity of her Nephrite pilots to give her recently emerged gem passing glances while they worked; afterall, the curiosity would pass with time, and the Nephrites would go back to focusing solely on their duty.
As the ship began to head into outer space, Yellow crossed her legs and rested her chin on her fist while resting her other arm on the armrest of her chair; she waited and watched as her Nephrites work on calibrating the ship's gravity engine and the Form Calibration for the ship's entire crew on board. Unlike an instance where a ship's entire crew is made up of a singular type of gem, and its form calibration for faster than light travel is to be engaged for said gem type, Yellow's ship is bigger and houses multiple types of gem rather than one type of gem; thus with its size and crew that is aboard the space faring vessel, some time is needed for the ship to be properly calibrated for its gravity engine to be properly dial to the correct calibration of settings for the ship's crew to properly work without their form being too distorted in its faster than light travel.
Yellow Diamond minutely glanced off to the side to see how well her Citrine gem as acclimating herself to her surroundings, and noticed how she was staring wide eyed and seemed to be taking in everything slowly; not a peep was uttered out of her Citrine gem, and Yellow chalked it up to her project's preprogrammed knowledge pouring into her mind. Off to the side, beside her chair, Yellow Diamond glanced to see her Yellow Pearl was sneaking glances at her Citrine as well.
'Honestly, is my little project of a Citrine Gem that interesting?' Yellow thought to herself with amusement.
Tanya
Sitting atop what she could only assume was the enormous woman's console desk, Tanya began to feel an influx of information rush into her mind. While the giant yellow woman was glancing elsewhere other than her, Tanya couldn't help but wince as information continued to be somehow fed into her memories; it didn't feel like her memories were being replaced by something else, it was more like something was feeding her information on everything she looked at.
Tanya brought her hand up and felt at her chest where there was now a Facet cut Citrine of a gem, she could feel the onrush of power and information feed from the focal point of the gem. In her mind, she was constantly being bombarded with more information than what a normal human could handle. Tanya continued to feel up to her head, and felt through her hair; she pulled and found that her tuft of hair was eerily reminiscent of what she had in her second life.
As information continued to feed into her mind, Tanya finally realized who the giant woman was and what kind of new sort of society she was part of. The Giant Yellow Woman is Yellow Diamond, and for all intents and purposes, Tanya was a Citrine gem that was made to serve within a caste system, at the moment however, none of the information has yet to explain what part of the supposed caste system she was in. She could only grouse and curse her luck, oh sure, she'd panic, but Tanya didn't live a long second life to react so violently so easily by now.
With her hands now both plopped down on the surface she sat on, Tanya began to glance around her and try to come to grips with her situation; the information that continued to feed into her mind did help in making her understand her situation, but it didn't help her come to grips that she was now in a situation where there was essentially no upward mobility…
Then again, as more information that was essentially flowing into her memories, she was learning more about herself that led her to finally realize that her duty was to act as an extension of Yellow Diamond…Her Diamond to be precise, seeing as how every gem speaks in a certain way towards the Diamonds that exist within the Diamond Authority. Most often, 'my' is used in a way when referring to a gem's owner and/or superior. Case and point, Tanya was to address Yellow Diamond in a respectful manner as 'My' Diamond, seeing as how Yellow is essentially her progenitor that made her.
More information continued to feed into Tanya's mind, one such detail gave her a glimpse of how many Diamonds exist so far; at present, there are four, and each one is different in color. White Diamond is essentially the head Matriarch of the Diamond authority…well, that's what Tanya thought to herself. On the whole, the entire race of gem society is genderless, but at the same time everyone is practically coded as female; thus, Tanya can only presume that the Diamond Authority is ruled by a matriarchy until she can fully understand her situation more and correctly categorize what sort of Empire she was now part of.
"Quite the curious look you got there, my little Citrine." Yellow Diamond said, bringing Tanya out of her thoughts, and making her blink before she looked up from her sitting position.
Blinking a few more times, Tanya pursed her lips before speaking up in a short stutter. "I-I-It's all new…my-my-my Diamond." Tanya spoke in a nervous low tone of voice.
"Hmm." Yellow Diamond made a hum of thought from her lips while looking down at her newly made gem, "I suppose it is, all new, in a sense." she quirked a lip of amusement as she glanced around at the insides of her updated yellow arm and hand ship. "But, seeing as how you just emerged, I must imagine you're still acclimating yourself to the knowledge of who you are and your standing within the Diamond Authority."
A slow nod from Tanya, "Yes…I am…getting a sense of what I am…" she worded out as she was still feeling quite overwhelmed by her situation.
Yellow Diamond smiled down at her as the ship began to finally initiate it's faster than light travel, "Good, I'll see about getting you a Pearl once we arrive at homeworld, before we get you on your first assignment." Her Diamond told her.
Tanya blinked, and hoped she could wrack her mind on what Yellow Diamond meant by getting her a Pearl; everything was still so new and off putting to her, but after a moment's time, Tanya was finally able to grasp what Yellow Diamond meant by getting her a Pearl. As more information fed into her mind, Tanya was able to understand that Pearls essentially function as attendants to high-ranking Gems, with several more functions.
Before Tanya could speak up or make another thought, the ship began to shift reality around it and create a gravitational singularity point to use its massive gravitational pull to warp space-time around it. Tanya felt an odd feeling as the ship sped through outer space, and when she dredged up what she could glean on what was happening, the ship was essentially constantly creating a gravitational singularity that evaporates in nanoseconds in front of it, which basically causes Yellow Diamond's ship to continuously fall towards the singularity and allow it to travel faster the light through outer space
"That look on your face, I can only presume your mind is being fed information on what is going on right now, correct?" Her Diamond asked of her with a curious gaze down at her, prompting Tanya to look up with an unsure look on her face.
"It's-er, yes." Tanya spoke up, hoping she wasn't being out of line in how she was acting in her situation so far, "You'll…have to forgive…me..my Diamond, I'm still coming to grips with my position as your right hand." she tried to explain herself.
Yellow Diamond curled an amused smile down at Tanya as she rested her cheek on her fist, "That's an interesting term, my Right hand…yes…" Yellow Diamond mused and lifted her cheek off her fist and used her hand to rub her chin in thought, "Quite the appropriate term for you, my little Citrine." Yellow spoke with a chuffed expression, before giving her Citrine a dangerous look. "Now…where's the salute? Surely that isn't missing in your memory bank." she mused with a small frown.
Tanya looked down and thought inwardly, before looking back up at Yellow Diamond with an unsure expression; Bringing up her arms, Tanya formed a sort of Rhombus with her arms and hands. "This-this is what you mean, my Diamond?" Tanya asked with an unsure look on her face.
Yellow diamond smiled at the speed at which her Citrine was learning, "Good, I am glad your settings are acclimatizing quite fast compared to most gems." she mused, all the while the soft hum of the ship's engine could be heard in the background as it sped faster than light towards its' destination, Homeworld.
Present, 4,500 B.S.U
Homeworld
After coming to the Aristocratic district of Homeworld, Yellow Diamond had her Carnelian Arbites work in conjunction with her Peridot gem bots in flushing out every Noble Gem and have them be processed in an impromptu shakedown within one of the aristocrat's many auditoriums. While Yellow Diamond stood and waited with her arms crossed till every aristocrat gem was brought to the auditorium that she was in, she couldn't help but make a contented smile.
She had to give her Citrine props in her proposal in using the Carnelian Gems as a planet's supposed judicial force, essentially a law enforcement to enforce the Diamond Authority's law on even the aristocratic caste. Yellow's Citrine had even given the suggestion of calling them Arbities, as essentially an Arbiter was a singular being and Arbities was its plural given form.
Yellow would have pondered where her Citrine gem was coming up with all her various new ideas, but then she had to remind herself that she herself had made her personal Citrine; so it stood to reason that her little Citrine would come up with such good ideas, she was afterall, her gem, created with her own essence; so it stood to reason that Citrine Facet 74ny4 would be able to come up with new ways to manage the Empire as a whole.
Bringing herself out of her thoughts, Yellow Diamond watched as her Carnelian Arbites could be seen herding every Aristocrat Gem on homeworld. An attendance would be put into effect, and whichever Pyrope was not in attendance, that was where she'd begin to know which Pyrope was pulling the strings over on Planet F78. By all accounts, every Aristocrat gem was supposed to be on homeworld for the Empire's quarterly review of how well the aristocrats were managing their colonies they were put in charge of.
However, with the recent debacle that was the incident within the Northern Quadrant, some aristocrats from said quadrant might have gotten the message a bit late since the Northern Quadrant was just now released from being blockaded for the sole purpose of her Citrine combing the quadrant of any more rebels. Yellow Diamond frowned in distaste, the Pyrope from the memories analyzed from the rebel gems, she would get to the bottom of this and analyze the memories of every aristocrat's memories and see if any of them were in cahoots with the traitorous Pyrope gem.
As the Carnelian Arbites finished herding in the remaining noble caste of gems, and said gems began taking standing positions within the auditorium, Yellow Diamond glanced across the crowd for the expressions of every aristocratic gem. Some ranged from curious to confused, only a few however looked nervous and a shy few had fear written on their faces. Well now, it seems some of them are either doing something they should not be doing, they are in cahoots with the traitorous Pyrope, or they were in the midst of doing something bad as well.
No matter, Yellow was going to make sure to show the noble caste why she was not to be lied to, and show what happens to traitors. She would make sure the noble caste knew that just because Blue was shirking her duties, that they couldn't think that they were above repercussions of their actions. Oh yes, she'd make examples out of the traitors she'd no doubt find with her own memory analyzer she had on hand. Already, she could see a few noble gems fidget in fear as the room quieted down and allowed her to begin discussing why she had every Aristocrat gem on Homeworld brought to the auditorium that she was in.
