This is a crossover for Star Trek: Voyager, Star Trek: The Next Generation, and Star Trek: Picard. Because of the limited ability of to show this, I wanted to point it out here.
Prologue
Aboard The Starship La Sirena, The Prophus Sector
To say former Starfleet Admiral Jean-Luc Picard felt troubled was the understatement of the millennia. Just three days earlier, Picard had found out that Dajh Asha's twin sister, Soji, was currently onboard the The Artifact, which just happened to be in Romulan space. He had finally found Bruce Maddox, only to have the famed cyberneticist die in the sick bay aboard the La Sirena.
His day was about to get worse.
As he was pouring over what little information he could find on The Artifact, his mind turned to Soji, wondering what exactly she doing onboard that mysterious vessel. Maddox had said that Soji was aboard The Artifact for the same reason Dajh had been sent to Earth: to find out the truth about the ban on synthetic life forms.
As he was taking a sip of the splendid Earl Gray he had replicated, he was approached by Raffi Muskier. Picard thought Raffi had departed for good at Freecloud, to find out about her son, but he had rejected Raffi out-of-hand. She returned to the La Sirena, locking herself away in her quarters for two days, before finally ending her seclusion, and rejoining Picard, Rios, and Jurati. She had been searching for information on the exact whereabouts of The Artifact.
While on station on The Bridge of the ship, some disturbing news had reached her from Freecloud. She entered Picard's quarters.
"JP", she said quietly, not wanting to startle Picard too badly.
The older man looked up at his associate. "Yes, what is it Raffi?"
Raffi took a seat next to Picard, and with a sad sigh, delivered her news. "I just received information from Freecloud. The authorities-such as they are on that place-have put out an APB on your friend Seven."
Picard fully came to attention. "An APB. What for?"
She sighed again. "She returned to Freecloud after leaving the ship, and she murdered Bjayzl, her two female attendants, and...and about thirty of Bjayzl's security people. She then vanished. And, from what I can gather, The Federation is trying to track her down."
"Good Lord", Picard whispered, feeling both horrified, and, on a more personal level, betrayed by Annika Hansen. Picard had felt physically ill when Seven of Nine had recounted the death of her "son", Icheb, at the Seven Domes on Vergessen, almost a dozen years earlier. He understood Seven's fury, and the reason she wanted to kill Bjayzl. Yet Jean-Luc had parted with Seven, thinking that she had seen to reason.
Her question to him, before departing, if he had regained all of his humanity after the Enterprise-D had severed him from The Collective, haunted him. He should have seen the warning signs in Seven's question, and her response.
But it was too late to curse himself for missing that.
A few moments later, both of them walked out to the Bridge. Rios was dozing off, as the ship made its way toward Romulan space.
"Rios", Picard said with a command voice any former Starfleet member would recognize.
He immediately came to. "Yes, sir?" He answered as any Starfleet member would to the sound of that command voice.
"I need you and Raffi to work discreetly on contacting someone back on Earth."
Rios looked at the man as if he had lost his mind. "Earth? Picard, if we contact Earth, it could tip off The Federation where we're at and what we're doing."
Picard raised his eyebrows, and gave a small smirk. "Discreetly, Rios, was the pejorative word in that sentence."
Rios got it. "Ah, gotcha", he said with a sly grin. "Who do you want us to, uh, discreetly, try to contact?"
"I need you to contact former Admiral Kathryn Janeway. She was Seven's Captain on Voyager when it was lost in the Delta Quadrant."
Raffi got it immediately. "I read up that Janeway and this Seven had a rather...interesting relationship when on Voyager, and for a while afterward?"
"'Interesting' doesn't begin to cover it, Raffi." Jean-Luc quietly sat down. "I fear the only person who might be able to reach Seven is Janeway. If Seven has bowed to her fury, many people, in many places, are in mortal danger."
"We'll get right one it, JP", Raffi promised.
"Make it so."
Two Days Later, Bloomington, Indiana
Kathryn Janeway had taken a walk back to the lake that bordered the home where she had grown up and now owned. When she had left Starfleet twelve years earlier, having done everything she could to keep The Federation and Starfleet from becoming overt militant entities, she had retired to this house, where her parents had raised her sister Phoebe and herself.
Her mother had passed away three years after she had returned the U.S.S Voyager to the Alpha Quadrant, following their seven-year ordeal in the Delta Quadrant. She had updated the home so it wasn't without twenty-fourth century conveniences, while keeping the basic tenor of the traditionalist lifestyle her parents had lived.
After the news she had received today, she had needed to get out of the house, and get some fresh air, after the communication from former Admiral Jean-Luc Picard. The air had helped.
But it didn't take away the devastating pain she felt in what the message had said.
"My God, Seven", Janeway lamented out loud, to no one but the lake, "what has happened to you?"
She hadn't seen Seven in a decade. Their once-close relationship had been all but destroyed when Seven had began a relationship with Chakotay shortly before Voyager arrived back to Earth. Kathryn had felt betrayed by her young protégé, who, too late, found out that the Captain was very much in love with the former Borg drone, but had hidden part of her feelings, demanding she deny herself any intimate relationships in the Delta Quadrant.
For her part, Seven had felt exactly the same way as Janeway, yet she had concluded that Janeway hadn't been interested. Less than a year after their return to Earth, Kathryn and Seven had met, in an attempt to clear the air.
It had been a disastrous meeting.
Seven had accused Kathryn of abandoning her, forcing her into Chakotay's arms, while they were still in the Delta Quadrant; Kathryn claimed that Chakotay and Seven, by hiding their romance, only telling her about it over dinner one night, had been the straw that broke the camel's back, sending Kathryn into a deep depression, and using a year of personal leave to all but vanish.
For the next five years, Kathryn had no contact with Seven or Chakotay, the bitterness of having their relationship held secret, then revealed during the long, tortuous debriefs, hearing, and, for Kathryn, a Court Martial which she had to endure. Even after being blindsided by both Seven and Chakotay, she had steadfastly defended them at the hearings, and at her Court Martial. Her testimony had convinced Starfleet to allow the Maquis members of her crew to continue to serve, if they chose, and had guaranteed the citizenship for Seven, Icheb, and the Doctor.
Yet neither Seven nor Chakotay had thanked her after the fact. In fairness, two days after the Court Martial had concluded, with Kathryn being promoted to Vice-Admiral, she had taken that leave and vanished.
The last time she had seen Seven was twelve years ago, after Chakotay had been killed in an anthropological expedition on Varnas VII, when a sudden plasma storm had descended on his team, and he had been hit by a bolt of plasma lightning.
Despite their estrangement, Kathryn had been devastated at the news, and had offered Seven her sincere condolences, which Seven had accepted. Yet by the end of the five days Kathryn had been on Dorvan V, the relationship with Seven was broken seemingly beyond repair. The bitterness that Seven displayed contained nothing that Kathryn Janeway recognized as Seven of Nine, only that of a disillusioned, angry woman.
Kathryn still had her sources, and she had kept track of the former drone, finding out a long time ago that she had joined the Fenris Rangers, a vigilante group dedicated to protecting former drones from attack.
Kathryn had been devastated by Icheb's death, and had become physically ill when reading what had happened to him. She had to run to the en suite to vomit, so upset had she become. She had to admit that part of her physical reaction was reading that Seven had gone on a killing spree in the last few days, to avenge Icheb's death, all those years ago.
That wasn't the Seven she knew and loved. This was someone completely alien to her. Despite their estrangement over the years, Kathryn's heart strings clenched, knowing that she had to do something. She couldn't simply let someone she still cared about destroy her life.
She had calmed down enough after about thirty minutes, going back inside her home. From there, she put out a subspace call.
