I don't own Star Trek, but I saw that Seven was the President of a totalitarian Earth in an alternate timeline, and I thought why not make a crossover?

CSS Vengeance.

Seven leaned back from the desk in the Presidential office - it all seemed bizarre that she happened to be the ruler of this alternate Earth but the differences between this world and the one she had returned to after spending so much of her life in the Delta Quadrant after Voyager returned thanks to the dubious efforts of Admiral Janeway that Seven, or Annika as she was referred to here were so startling that Annika expected to wake up.

But she knew this was no dream.

Somehow she had found herself arriving in a parallel timeline where she was president of a totalitarian regime, an interstellar empire with Earth in the middle of it. But how?

Annika (Seven had often thought of resuming her original identity when she had returned to the Alpha Quadrant, she might have been Seven of Nine for as long as she could remember, but there had been times where she would have given anything to be Annika Hansen again) didn't know if the rest of the Stargazer crew had survived and had woken up to find themselves in this reality. She would adapt herself. As a former Borg drone, her knowledge of temporal theory gave her an edge, but she was so bemused by the differences in this universe to her own.

The United Federation of Planets did not exist here, Earth - this Earth was a badly damaged, heavily polluted world that was still just habitable that Annika was surprised after discovering how extreme the environmental damage was - was the capital world of a xenophobic government and race of humans who were fighting seemingly endless wars against 'warlike and savage alien races,' boldly exterminating them or subjugating them until the alien races bowed their heads and put on their chains to stop the carnage, or they were still trying to gain their freedom from oppression.

She had been looking through the records of the numerous wars this…Confederation was waging in the galaxy; she had made a few careless mistakes here and there with the PA and the android that reminded her of the synths before the Romulans reprogrammed them in her own reality, but hopefully, she hadn't made too many for the people here to be suspicious, and she was amazed there was still resistance at all, given how ruthless and expansionistic the Confederation was.

Adapting here was not going to be easy, especially since she was a long way from working out for herself how she had come to be here. Still, she had to start from somewhere.

"Computer, access historical files. Display map of the Confederation from the start of the year," Annika ordered the computer, figuring that if she had some idea of how large the empire was she might have a better clue as to what they were doing.

A map of the galaxy appeared on the display in front of her, the familiar graceful curves of the galaxy with its outflung arms that had been a staple of her duties on Voyager in the Astrometrics lab almost made her smile but when she saw the blobs of space that reminded her of the shapeless masses of amoebas her expression became quizzical.

By far the largest blob was the one contained in the Sagittarius Arm of the Milky Way, the arm that contained the Federation and other powers in the Alpha Quadrant as she knew them best, which wasn't connected to the galaxy and its other arms by anything other than gravity. As other arms in the galaxy had done over the centuries, the Sag Arm had been sprayed off the mass, as a droplet flung away from the mainstream of a flow of fast running water.

Annika knew the arm would reconnect with the rest of the galaxy again, but the time scale was so wide that for most sentient lifeforms it wouldn't happen in their lifetimes. The Sag Arm was discrete for now, but soon it would join back with the galaxy but it was a process of melding that would make millions of centuries. For Federations and Empires concerned with expansion on a modest scale, the problem of reaching other worlds didn't really arise.

But the Confederation had bypassed that problem already. While the Alpha and Beta Quadrants of the galaxy had been successfully conquered despite the wars going on, they had managed to effectively conquer all known space and even beyond. The Bajoran wormhole that led to the Gamma Quadrant had opened up whole new worlds to conquer, new opportunities. Indeed, Annika got the impression that the wormhole's discovery was one of the primary reasons why the Confederation had conquered that part of the Milky Way so completely, but it had brought them into conflict with the Dominion who had been an oppressive regime in the Gamma Quadrant for centuries.

Like all Borg, Annika had known about the Dominion even before Voyager took her away from the Collective. And she had given the crew her knowledge of them and their methods, but when news of the Dominion War of her reality had come to Voyager, first through the report the Doctor had given following his encounter with the Prometheus and then in those letters Voyager had received shortly after, Annika remembered the shock and horror of the entire crew.

But here the Dominion was still fighting, but if they were going to succeed Annika didn't know. The Jem'Hadar were good soldiers and she knew it, but they were used to fighting small wars and not an invasion from the other side of the galaxy. The Confederation had been fighting in the Gamma Quadrant now for decades, and the blob that represented Confederation territory in the Gamma Quadrant was growing bigger and bigger.

But as she looked at the map and she saw the number of blobs in the Delta Quadrant and the outskirts of the Gamma Quadrant, Annika wondered what was happening and why they were so wide apart, separated by hundreds of light-years.

"Computer, display a map of the Confederation as of…," Annika chewed her lip thoughtfully as she tried to pick out a specific year and it came to her in a burst of inspiration, "2200." What better place to start than the beginning of the century where the Federation would be in one of its golden ages?

The map of the galaxy remained the same, but this time there was a very small blob imposed on the Sag arm. Against the galactic backdrop, it was a very small amount of space, but Annika knew that the blobby mass of the Confederation had conquered a large amount of space.

"Go forward in ten-year increments," Annika ordered before she took a sip of her coffee, smacking her lips in delight at the taste; ever since the day her body had adapted to living without the doses of energy she'd received from Borg regeneration alcoves, she had been growing her pallet, "go forward until the current date."

The blob increased its size as the lines of explored space grew bigger. It was only 10 per cent bigger than before. The screen blinked as the Confederation expanded again, reaching along the galactic arm like a vine spreading forth across a wall, spreading towards the rim.

As the blob expanded with glowing shapes as the percentage of the space was explored and conquered and then colonised forcefully by this version of humanity. The largest chunks of expansion in the 23rd century took place in the final decades, shortly after the newest ships were added to the fleet after the warp scale was addressed. These ships would go on to become the backbone of Starfleet.

It seemed the same thing had happened here as well, although the sheer amount of space expanded as the exploration took place before the exploitation ambitions of the Confederation reared its head had pushed the Confederation into a corner. The 2330s saw a massive growth of explored areas of space, but it wasn't until 39 years later that, as was constant and consistent with the history Annika herself remembered, the Bajoran wormhole had been discovered giving the Confederation new places to explore and exploit.

But the confusion came for Annika when, in the Delta Quadrant and in the outskirts of the Gamma Quadrant, smaller blobs of space appeared and because the Delta and Gamma Quadrants were neighbours and judging from the position of some of the blobs which were growing bigger and bigger with each decade according to the map until they joined with one another and became larger than the Confederation had been in the 23rd century.

One of the curious things about these territories were they sprang up, completely unexpectedly. They were not joined with any of the larger territories in the Gamma and Alpha and Beta Quadrants by any visible lines of exploration.

The blobs in the Gamma Quadrant were getting bigger and bigger and spreading out over thousands of light-years that it would not be too long before they joined with the territories conquered and occupied by the Confederation that already existed. In fact, it seemed the strategists and the generals of the Confederation's armed forces had thought of that plan and were making sure it went through, they had ordered small amounts of space to be conquered and for the armies there to expand, on and on until they reached the larger territories occupied.

The last two decades of expansion were the largest of all. By now much of the Delta and Gamma Quadrants had been conquered and occupied, with the Delta Quadrant territories joined together until now much of it was occupied by the Confederation, but the sheer amount of space conquered surprised her.

Annika recognised much of the space from her time on Voyager. She could see Kazon and Vidiian space was joined together, as were the Voth and Nyrian territories, and that worried her.

But Annika had noticed something about the year these smaller territories appeared. They had appeared two decades following the return of Voyager, in the year and the month Annika herself remembered. It was logical to assume the Caretaker had existed in this reality, and that they had snatched a ship from the Alpha Quadrant.

"Computer, access files on the life form known as the 'Caretaker,'" Annika ordered.

The file on the Caretaker was extremely large and informative. Like the counterpart in Annika's own reality, this version of the Caretaker had been a Nacene explorer who had made the mistake of critically damaging the Ocampa homeworld's atmosphere until the Ocampa were forced underground, and the Caretaker was one of two individuals meant to care for them. As in Annika's reality, the Caretaker was discovered dying and desperately trying to ensure the protection of the Ocampans, through kidnapping other races in the hopes of reproducing. But it hadn't worked. And so, an increasingly desperate Caretaker continued the kidnapping of other races and beings in the galaxy, many of them were survivors running from the Confederation, but the Confederation themselves were not brought to the Delta Quadrant until the CSS Equinox and then later, the CSS Vengeance.

"Computer, display files on CSS Equinox and CSS Vengeance simultaneously," Annika held back the urge to shudder when she saw the name Equinox.

The computer showed her the images of two ships she had known very well, the Equinox and the second one that she recognised as Voyager, but if this was an alternate Voyager, then the name was off. According to Confederation records, the Equinox had been a light cruiser and scout ship that had been dragged into the Delta Quadrant. Annika made a face as she saw that a large half of the crew had been killed much like they had been in her reality, from what Ransome had told them after they'd saved them. The ship had been too small to truly make a difference against the odds, and they were forced to return home, stealing supplies and technologies as they limped home, but events followed the same pattern they had in Annika's own reality, but here Ransome and his crew were celebrated for the murder of the life forms whose corpses left large amounts of rich, potent antimatter fuel.

The CSS Vengeance had it lucky. The ship had gone down in history for their epic journey through the Delta Quadrant, for the extermination of numerous races in order to destabilise the quadrant sufficiently for the real invasion.

That explained the many successes the Confederation had in the Delta Quadrant, Annika realised.

Under the command of its captain, Colonel Kathryn Janeway, the CSS Vengeance had been sent to wipe out a Maquis cell, captained by Chakotay (some things didn't change, Annika thought with a wry smile as she thought about her shipmate, but she was horrified when she learnt this Chakotay and his crew had been killed by this version of Janeway) - there were some people in the Confederation who truly did not like what their people had become, and they were trying to stop them, but their efforts were few and far between since so many people followed the propaganda of aliens being savage, evil, and warlike, and the Confederation was merely protecting themselves - but they had instead embarked on a seven-year trip, cutting a path of murder and destruction and war throughout the Delta Quadrant.

Along the way they had stolen numerous technologies, starting with large amounts of technology from the Caretaker who had realised too late he had kidnapped a group of monsters who would exterminate or exploit the Ocampa, and it was only his last effort to destroy the Array that the Vengeance was stranded there at all. Some of the Array survived and were salvaged by the Vengeance crew. But along the way they stole Vidiian, Nyrian, even Voth technology, but the biggest boons came when they stole Arcturus's Quantum Slipstream Ship instead of just merely studying it.

Sadly they discovered the limitations of that drive just as Seven's version of the Voyager crew had done, but they had found the graviton catapult (even to this day she still cringed as she recalled her paranoid behaviour), and the Vaadwaur underspace network. In fact, that was how they had come back to the Alpha Quadrant, and they had passed that information along. They had tortured Arcturus, Tash, and some of the Vaadwaur until they had found their way home. That was how the Confederation had managed to conquer large amounts of space, by sending out fleets of ships powered by Quantum slipstream drive, or catapulting them through graviton catapults while other fleets were sent out to explore the Underspace and conquer parts of the galaxy at random.

"Computer, access biographical file, Colonel Kathryn Janeway," Annika ordered.

The computer file on Janeway was extensive; while Annika could recognise some similarities between this Janeway and the one she had known on Voyager, there were significant changes and differences here as well, which had transformed Kathryn Janeway from a curious explorer to a hard, cold, and ruthless soldier. As she scrolled through this Janeway's file, Annika could find very little similarity between this version and the one who had become her self-appointed mentor who had done more harm than good by dropping her into the deep end and expecting her to thrive without help.

The list of atrocities this Janeway had committed was staggering; the extermination of the Ocampans (apparently their race were too telepathic to be allowed, and their brief life-spans meant they were useless as servants), the brutal campaigns against the Kazon and the Vidiians which ended with the capture of the Phage although Janeway had it modified and augmented so the plague hit the Vidiians so hard they barely survived. Even now the pockets of them who had survived were holding onto life by a thread.

The Swarm. The Nyrians. The Sikarrians. The Talaxians. The Haakonians. All conquered. The Cravic and Pralor robots had been reprogrammed and were now fighting for the Confederation, their already brutally advanced weapons added to that of the warships fighting under Earth's authoritarian banner.

The Vengeance crew had captured Voth technology and even now they had barely scratched the surface of it, but what they had gleaned had given them the means to become even more aggressive. But it was the encounters Vengeance had with the Borg that worried her. According to the file on the Vengeance service record, they had come across a Borg cube and tore it apart to understand its technology better, and when they were finished they had become experts in fighting the Borg, setting up the precursors for augmented Quantum torpedoes and Transphasic weapons that could cripple a Cube outright.

When they returned home, Vengeance had, as Voyager had, been thoroughly checked out and the new technology was given to the scientific minds in order to develop more powerful weapons and technologies. One of the biggest boons was the Metreon Cascade which had virtually exterminated the Talaxian colony, Rinax. The Voth shuttle stolen from the scientists who were killed after they were discovered was one of the biggest prizes, but the discovery of Underspace gave the Confederation the means to reach new territories quickly and subjugate them as fast as possible.

In any case, the Confederation scientists needed time to recreate the advanced propulsion methods Vengeance had brought back, and led by the CSS World Razer which was apparently this world's version of the Enterprise D, and the Vengeance and many other ships, the conquest of the Delta Quadrant began. It was a long, lengthy and brutal retelling of the way both the Delta and Gamma Quadrants were heavily explored and conquered although it would likely be a long time before the galaxy collapsed under the Confederation's never-ending war efforts.

But it would happen, and when that happened they would move on to other galaxies. They certainly had the means. The latest warships were leaving the shipyards in fleets, heading to the distant territories and overwhelming the enemies humanity had.

No Federation.

No diplomacy until the aliens were so battered down they had only sticks and stones to fight with. The Confederation preferred extermination of the enemy

But now the Confederation were getting closer and closer to truly subjugating the galaxy. They had Protostar Drives, Graviton Catapults, Quantum Slipstream Drives, modified Nyrian translocators, spatial trajectors stolen from the original technology owned and used by the Sikarrians, in addition to their traditional warp drive technology. But with the Vaadwaur underspace under their direct control now they had succeeded in wiping out everyone they encountered, or they had subjugated worlds who were scared of them. Thanks to the Underspace, the Confederation had a natural means of travelling through the galaxy and crossing to distant regions while filling in the gaps between the distant territories they were occupying until they joined together.

What is the point of all of this? Annika thought to herself. She had seen some of the worst of humanity, but this was beyond her.

But what had caused all of this, Annika did not know. All she knew was when she switched back to look at the map of the galaxy, and listened to General Jean Luc Picard's speech about the conquest of the galaxy on behalf of humanity, finding a way to stop this was going to be next to impossible.

But Annika - Seven of Nine - had encountered many strange things in her life since her liberation. She had become a vigilante when her life on Earth had turned sour. But she was out of her depth here, she needed time to regather herself.
