Timeline - Post-Nemesis Era (Since 2380)
Around 2380 Jack Crusher is conceived on Casperia Prime. Jean-Luc Picard and Beverly Crusher part ways two months later (PIC: "The Next Generation", "Seventeen Seconds").
Around 2381 Jack Crusher is born (PIC: "The Next Generation", "Seventeen Seconds").
Jack's exact age is never stated, but we can infer it from the statements that Picard hasn't seen Crusher in 20 years and that Jack was conceived on Casperia Prime two months before they parted ways. And yes, Ed Speleers is and looks a lot older than that.
2381 Thaddeus Troi-Riker is born (PIC: "Nepenthe").
2381 Geordi La Forge begins to restore the USS Enterprise-D. (PIC: "Vox")
Early 2380s A group of Romulan women, all members of the Zhat Vash, venture to the planet Aia to experience the "Admonition". Most of them become insane and kill themselves just after the ceremony (PIC: "Broken Pieces").
The caption in "Broken Pieces" places this event in the year 2385, which is an error. Ramdha is not yet assimilated at this time, and the attack on Mars was explicitly said to have been plotted after the Admonition. The timeline of the evacuation of Romulus, the Mars disaster and the Romulan nova would (barely) allow 2385 as the latest possible date for the Admonition. But then the year 2383 that can be inferred from "Maps and Legends" for the last assimilation on the Artifact would be wrong. Perhaps the 5843 days on the sign do not refer to Earth days, but if this were true why would it be in English language?Later in the early 2380s A Borg cube encounters two Romulan vessels operating for the Tal Shiar, of which the Shaenor is assimilated, which subsequently leads to a submatrix collapse on the Borg cube. The Romulans take possession of the ship, which becomes known as the "Artifact" (PIC: "Maps and Legends", "The End is the Beginning").
2383 The last assimilation takes place on the Borg cube known as the Artifact (PIC: "Maps and Legends").
A sign inside the Artifact says that as of 2399 "this facility has gone 5843 days without assimilation". Under the good assumption that on the English-language version the day length is 24 hours, this equals 16 Earth years minus one day (with 2384, 2388, 2392 and 2396 being leap years). It is well possible that assimilations stopped the very day the Borg cube was brought down, probably soon after the encounter with the Shaenor, so this most likely all happened before the destruction of Romulus.
Prior to 2385 Starfleet prepares a large-scale evacuation of Romulans, as their central star is about to go nova. Admiral Picard is in charge of a rescue fleet that is being built at Utopia Planitia on Mars. On Vashti, a planet that is meant to be a temporary home for Romulan refugees, he meets a Romulan boy named Elnor, who is raised by the Qowat Milat order. 14 Federation member worlds threaten to pull out in case the Federation helped the Romulans (PIC: "Remembrance", "Maps and Legends", "Absolute Candor").
In "Star Trek (2009)", a star exploded, its shockwave "threatened to destroy the galaxy" and Spock promised the Romulans that he would save their planet, according to the very words of Spock. In "Remembrance", the FNN journalist speaks of the "Romulan supernova" and that "the Romulan sun was going to explode", which obliterated just Romulus (and the unmentioned Remus) and left safe spaces "outside the blast radius of the supernova". While only the latter scenario makes scientific sense, it is an extremely different story. It would be totally futile if Spock tried to stop a normal supernova by opening a black hole inside the Romulan star system because the planets would be lost in every conceivable outcome, no matter if they get blasted away by the supernova, get swallowed by the black hole or remain without sunlight in case a black hole with the same mass replaced the sun. In other words, for the very story of "Star Trek (2009)" to still make any sense, without letting Spock appear as a moron, in "Remembrance" the journalist must be lying all the time about what happened, and even Picard doesn't contradict while speaking with her. Either that, or there are two different continuities.2385 On April 5 (Federation Day), Utopia Planitia Shipyards and the Mars colonies are completely destroyed and 92,143 lives are lost. The devastating attack is ascribed to "rogue Synths". However, it was actually planned and executed by the Tal Shiar, and more precisely by a splinter group, the Zhat Vash and one of their undercover operatives, Commodore Oh. The consequence is a total ban on synthetic lifeforms in the Federation, including all practical research. Also, Starfleet abandons the evacuation plans for the Romulans (SHO: "Children of Mars", PIC: "Remembrance", "Maps and Legends").
2385 After protesting against the decision not to resume the rescue efforts, Picard resigns from Starfleet. Raffi Musiker too leaves Starfleet (PIC: "The End is the Beginning").
After 2385 The Romulan Neutral Zone collapses in the wake of the large-scale evacuation of Romulus. The Fenris Rangers begin to maintain a semblance of order on the worlds that were abandoned (PIC: "Stardust City Rag").
The statements in the episode indicate that the collapse was a consequence of the evacuation, rather than of the nova. It is not explicitly mentioned, but the Federation may have been unwilling to fill the vacuum of power.
2386 Picard stores the painting "Daughter" by Data in the Starfleet Quantum Archives (PIC: "Remembrance").2386 Icheb is captured on the planet Vergessen, and his Borg implants get removed by Bjayzl. Seven of Nine can't help any more and mercy kills him (PIC: "Stardust City Rag").
2387 The supernova destroys the Romulan star system (PIC: "Remembrance").
Spock's effort to save Romulus is not mentioned in any form in Star Trek Picard.
2389 A ship with Beautiful Flower and Jana, two Synths, leaves the planet Coppelius and encounters the USS ibn Majid. Captain Alonzo Vandermeer receives "orders" from Starfleet Security to kill the two passengers. He complies and then commits suicide, as witnessed by his first officer Cristóbal Rios (PIC: "Broken Pieces").
In "Et in Arcadia Ego I", Arcana says that the Synths on Coppelius only had that one ship and can't leave the planet. But Bruce Maddox, as well as Dahj and Soji must have departed from Coppelius after 2389.
2389 Jean-Luc Picard and Worf meet for the last time before 2401 (PIC: "The Bounty").
Around 2395 As the treatment with a positronic matrix that could help him is not possible because of the ban on research on synthetic lifeforms, Thaddeus Riker loses his fight against mendaxic neurosclerosis (PIC: "Nepenthe").
2395 A musical festival takes place on Bewlay Island, Stardust City (PIC: "Nepenthe").
Quite possibly going to that festival was on Thaddeus's bucket list. We don't know if he still made it.
2395 Picard gifts Geordi La Forge a bottle of Château Picard, which is too dry for Geordi's taste (PIC: "Surrender").2396 Captain Liam Shaw assumes command of the USS Titan-A (PIC: "The Next Generation").
2396 Soji believes to have departed from Seattle on May 12 that year, heading to the Artifact aboard the Ellison. However, her name is not on the passenger list. According to quantum dating of Soji's belongings and to Jurati's research of Dahj's records, their history doesn't date back further than to this year (PIC: "Maps and Legends", "Absolute Candor", "The Impossible Box").
2396 Jack Crusher goes to Ten Forward to talk to his father but doesn't reveal his identity (PIC: "No Win Scenario").
2398 Narek's brother dies, according to Narek (PIC: "Remembrance").
This may well be a lie. We don't know if it was ever meant to have any further significance.2399 PIC Season 1 (see here)
A mysterious young woman named Dahj, who may be a descendant of Data, gets killed by Romulan agents. Without Starfleet's support, Picard assembles a team including Raffi Musiker, Cristóbal Rios, Agnes Jurati, Elnor and later Seven of Nine, to save Dahj's possible twin. After finding Bruce Maddox, Jurati secretly kills him because she was coerced to do so by Commodore Oh. Picard finds Dahj's twin sister Soji on the Artifact. Hugh, director of the Borg Reclamation Project, however, is killed by a Romulan operative. An ancient Romulan organization, the Zhat Vash, that strives to destroy all artificial life, is on the way to Soji's homeworld Coppelius. The Synths on Coppelius, on the other hand, try to enlist the help of an intergalactic synthetic civilization. Picard can convince Soji to trust him and stand down. Picard, however, dies of his neurological disorder. With the help of Dr. Jurati, Altan Soong transfers the admiral's consciousness into a golem. On Coppelius, the reborn Picard fulfills Data's last wish: to end a simulation of him that is still running. The Federation lifts the ban on synthetic life.
2399 Zhaban dies of unknown causes (PIC: "The Star Gazer").
This happens one and a half years before the episode.
2400 Deep Space 4 shuts down. (PIC: "The Next Generation").2401 PIC Season 2 (see here)
Admiral Picard arrives on the USS Stargazer to investigate a mysterious message from an anomaly that requested his presence. The Borg Queen appears on the bridge and is about to take control of the ship and of the rest of the fleet. Picard has no other choice but to order the self-destruct. The Stargazer explodes. Picard wakes up in his château and is greeted by Q. Picard, Raffi, Seven, Jurat, Rios and Elnor are in a changed reality, in which Earth is the fascist Confederation. They take La Sirena and escape with the Borg Queen to the year 2024, the supposed point of divergence, but Elnor is killed in the course. With the help of Guinan, Picard finds Supervisor Tallinn. She secretly watches of NASA astronaut Renée Picard, who is about to embark the Europa Mission. Q and Adam Soong repeatedly try to disable or kill her. In the end, Picard and his crew fix history, but at the expense of Tallinn's life and of Jurati, who gets assimilated and becomes the new Borg Queen. Q has set up this scenario for Picard to learn something about his past, and also to say farewell because his forces are dwindling. Rios decides to stay in the 21st century. Back in 2401, Elnor is alive again. Picard now recognizes that the Borg Queen is Jurati. He halts the self-destruct and allows her to join the shields of the ships to seal an anomaly that threatens the galaxy. 2401-2402 PIC Season 3 (see here)
After having no contact for 20 years, Picard receives a distress call from Beverly Crusher. He and Riker embark the USS Titan-A for a rescue mission, with support of Commander Seven of Nine, but to the chagrin of the ship's captain, Liam Shaw. They save Crusher and her son Jack from their ship, which is being attacked by an unknown vessel under the command of a woman named Vadic. Jack's father is no one else but Picard himself. Vadic begins to chase the Titan. She is a Changeling, and wants to take revenge on the Federation, for which she needs Jack for some reason. Jack begins to experience visions and develops unnatural powers. The Changelings kill Ro Laren, as she investigates the infiltration of Starfleet by them. Raffi and Worf find out that the Changelings broke into Daystrom Station, a secret research facility. Picard sets a course for the Fleet Museum, to ask Geordi to gain access to the facility. When he refuses, Jack and Geordi's two daughters install a Klingon cloaking device, which allows the Titan to approach the station undetected. Raffi, Worf and Riker retrieve a Soong android that contains the identities of both Data and Lore. But Riker gets captured by Vadic, who has also kidnapped Deanna. On the Titan, Geordi activates the android. Picard and his crew set a trap for Vadic. She gets captured but then manages to escape and take over the ship. After freeing Riker and Troi, taking back the Titan and killing Vadic, Picard's crew is re-united - even Data is with them again, as his personality has prevailed in the android's inner struggle. Reading Jack's mind, Troi finds out that the true enemy is not the Changelings but the Borg. Jack runs away to confront the Borg Queen but gets assimilated and hooked up to a huge transmitter. Picard and Crusher find out that the Changelings have tampered transporters fleet-wide to modify the DNA of Starfleet personnel with an old genetic code of Locutus, to be susceptive to messages from Picard's son. They assimilate the younger crew members during a fleet demonstration on Frontier Day, upon which the ships begin to fire on Earth Spacedock. Picard, Crusher, Worf, Geordi, Data, Riker and Troi escape from the Titan, whereas Shaw gets killed and Seven and Raffi stay behind. Geordi reveals that he has been restoring the Enterprise-D, which the crew uses to fight the Borg ship in the atmosphere of Jupiter. Picard can convince his son to return to him. After destroying the transmitter, the assimilated crew members are returned to normal. One year later, Jack embarks on his first space mission on the Titan-A, now rechristened Enterprise-G.
