Starship Enterprise -D responds to a distress call from the science vessel Raman, finding it in orbit around the planet Marijne VII. A rescue mission using the experimental interface probe reveals that crew of the Raman had been accidentally killed by subspace beings who live in orbit of Marijne VII. One of the beings, trapped aboard the Raman, communicates a message that it is trapped aboard the Raman. At significant risk to his personal safety, Geordi La Forge uses the interface probe to return the Marijne VII beings back to their home in low orbit.
Enterprise -D chief engineer Geordi La Forge learns that his mother, Captain Silva La Forge of the Starship Hera, has been lost, along with the rest of her crew.
• Services for the Hera crew are held on planet Vulcan, homeworld to many Hera crew members. Private services are held by the La Forge family for Silva La Forge.
After “Interface” (TNG).
• Captain Jean-Luc Picard, investigating a series of recent raids on ancient Romulan archaeological sites, is captured by mercenaries at a bar on planet Dessica II. Eyewitnesses to the incident report that Picard was killed by a blast from an energy weapon.
Picard’s captors were, in fact, the mercenaries who had been responsible for the raids on archaeological sites in the Taugan sector. Picard manages to convince them that he is a smuggler named Galen and offers his services to help appraise the stolen artifacts.
Several weeks before “Gambit, Part I” (TNG), but after “Interface” (TNG).
• A minister of the Bajoran provisional government is reported to have been attacked and beaten. The attack is believed to be the work of the Circle, whose acts of violence in the streets of Bajor have increased dramatically.
Two days before “The Circle” (DS9).
~1:[3,#B],171:[1,#I],185:[6,#I]@1“The Circle” (DS9)@2(No stardate given). Terrorist activity sponsored by the Circle continues to escalate on Bajor and on station Deep Space 9. Despite efforts by the provisional government to suppress the violence, the Circle appears to operate with impunity. Evidence is uncovered that the Circle is obtaining weapons from Kressari agents, and further investigation suggests that the Kressari are acting as intermediaries for Cardassian forces seeking to destabilize the Bajoran government.
Starfleet admiral Chekote, upon being informed of the deteriorating situation on Bajor, and citing Prime Directive prohibitions against involvement in what is essentially a local dispute, orders the withdrawal of all Starfleet personnel from Deep Space 9.
• Enterprise -D personnel investigate the disappearance of Captain Jean-Luc Picard at planet Dessica II.
Shortly before “Gambit, Part I” (TNG).
~1:[4,#B],36:[1,#I]@1“Gambit, Part I” (TNG)@2Stardate 47135.2. Evidence gathered at planet Dessica II suggests that Captain Picard had been killed by a blast from an energy weapon, and Commander William Riker receives authorization to place the Enterprise -D on detached duty to further investigate the incident. During the investigation, Riker is kidnapped by a mercenary group led by Arctus Baran. Aboard Baran’s ship, he discovers Picard, who is posing as a smuggler named Galen.
~1:[3,#B],138:[4,#I]@1“The Siege” (DS9)@2(No stardate given). Starfleet and other Federation personnel evacuate station Deep Space 9 as Circle forces arrive to take control of the facility, part of the Circle attempt to seize power from the Bajoran provisional government. A handful of Starfleet personnel remain aboard Deep Space 9 in violation of orders and are successful in retaking the station from Circle operatives, although Bajoran resistance leader Li Nalas is killed in the operation.
• Starfleet personnel return to station Deep Space 9 as Starfleet reassumes administration of the facility.
After “The Siege” (DS9).
~1:[4,#B],81:[1,#I],165:[5,#I],196:[6,#I]@1“Gambit, Part II” (TNG)@2Stardate 47160.1. Picard and Riker infiltrate Baran’s crew in an effort to discover the reason for Baran’s raids on Romulan archaeological sites. They learn that Baran has been employed by a militant Vulcan separatist group seeking to reassemble the pieces of the Stone of Gol. The ancient artifact, long thought to be mere myth, is found to be a functional psionic resonator weapon that enables the bearer to kill telepathically. Picard and Riker, with assistance from Enterprise -D personnel, are successful in apprehending Tallera, a member of the separatist group who had masterminded the operation. The psionic resonator is turned over to Vulcan security minister Satok, who promises that it will be destroyed.
• Quark arranges for a Klingon operative named Yeto to visit station Deep Space 9 in order to purchase liquid data chains. In preparation for the transaction, Quark agrees to plant an illicit device to defeat station security sensors so that Yeto’s arrival will not be detected.
Prior to “Invasive Procedures” (DS9).
• A violent plasma storm in the Bajoran star system forces evacuation of station Deep Space 9, leaving behind only a skeleton crew aboard the station.
Just prior to “Invasive Procedures” (DS9).
~1:[3,#B],17:[1,#I],118:[4,#I],123:[2,#I],190:[4,#I]@1“Invasive Procedures” (DS9)@2Stardate 47182.1. Deep Space 9 personnel render aid to the crew of the Ekina, a small space vessel reportedly damaged by the plasma storm. Their arrival is a ruse arranged by Quark for the sale of liquid data chains. The sale itself is quickly found to be a cover for Yeto’s real objective: Yeto has delivered unsuccessful Trill initiate Verad to DS9, where he intends to steal the Dax symbiont from Jadzia. Although Verad is successful in forcing the removal of the symbiont from Jadzia and its implantation into himself, Verad is thereafter overpowered, and the Dax symbiont is returned to its rightful host.
• Verad and his accomplices are turned over to authorities.
After “Invasive Procedures” (DS9).
• U.S.S. Enterprise -D travels to Starbase 84 for installation of a new warp core assembly. The core had been manufactured on planet Thantos VII using a new interphasic fusion process.
Commander William Riker gives Alexander Rozhenko a new music program. Young Alexander enjoys the music, an Earth form known as jazz, but his father, Worf, finds it unpleasant and is annoyed that Alexander plays it every night.
Prior to “Phantasms” (TNG).
~1:[2,#B],107:[1,#I],155:[1,#I],167:[3,#I]@1“Phantasms” (TNG)@2Stardate 47225.7. Commander Data finds that his dream-inducing program is now generating nightmares, which he finds to be an unsettling experience. Shortly thereafter, Data finds himself having “waking dreams,” in which he is unable to control his behavior. In one such waking dream, Data stabs and severely injures Counselor Deanna Troi. It is learned that the nightmares are caused by interphasic parasites that came aboard the ship in the new warp core, and that these life-forms are making operation of the warp drive system impossible. Once the nature of the parasites is understood, they are eradicated from the ship with a high-frequency interphasic sweep.
Enterprise -D captain Jean-Luc Picard is honored with an invitation from Admiral Nakamura to attend Starfleet’s annual Admirals’ banquet at Starbase 219. Unfortunately, the technical difficulties with the ship’s new warp core make it impossible for Picard to attend.
• A new warp conduit is replicated by the Enterprise -D engineering staff, replacing the parasite-infested unit installed at Starbase 84.
After “Phantasms” (TNG).
~1:[2,#B],132:[1,#I],182:[5,#I]@1“Cardassians” (DS9)@2Stardate 47177.2. Cardassian citizen Elim Garak is assaulted by Rugal, a Cardassian youth whose adoptive Bajoran parents are passing through station Deep Space 9. Cardassian authorities suggest that the bizarre incident might have been the result of Bajoran foster parents teaching their adoptive Cardassian child to hate Cardassians. Investigation into the incident by station commander Benjamin Sisko reveals this to be true, but further reveals that Rugal’s initial placement into a Bajoran orphanage eight years ago was a plot intended by Gul Dukat to embarrass Rugal’s natural father, Kotan Pa’Dar. Despite the fact that Rugal’s adoptive parents have cared for and loved Rugal, Sisko rules that the Cardassian youth has been the victim of Dukat’s conspiracy, and orders Rugal returned to the custody of his birth father.
• The Enterprise -D receives a delegation of Cairn representatives. These people communicate purely by telepathy and have no spoken language. The Cairn are accompanied by Ambassador Lwaxana Troi, whose telepathic abilities help the Cairn in what is to them, a very alien world. Troi’s valet, Mr. Homn, remains on planet Betazed.
Prior to “Dark Page” (TNG).
~1:[3,#B],28:[1,#I],129:[4,#I],202:[4,#I]@1“Dark Page” (TNG)@2Stardate 47254.1. Ambassador Lwaxana Troi is taken ill because of excessive use of her telepathic abilities in communicating with the Cairn delegation aboard the Enterprise -D. Treatment of Troi indicates her condition has been exacerbated by an old psychic trauma to her metaconscious. The trauma is relieved when Ambassador Troi is able to acknowledge the source of her pain, the death many years ago of her older daughter, Kestra Troi. This is a significant revelation to Deanna Troi, who had not been aware that she had a sister.
• A new restaurant opens on the Promenade at station Deep Space 9. The new eatery features traditional Klingon-style cuisine, prepared by a master Klingon chef, who even takes pride in serenading his customers with Klingon music.
Prior to “Melora” (DS9).
• Starfleet Ensign Melora Pazlar is assigned to duty at station Deep Space 9 as a stellar cartographer. In preparation for her arrival, Chief Miles O’Brien and Dr. Julian Bashir modify a suite of living quarters to allow the artificial gravity to be shut off to approximate the low gravity conditions on her homeworld. They also fabricate a wheelchair to allow her mobility throughout the rest of the station.
Prior to “Melora” (DS9).

Ensign Melora Pazlar arrives at station Deep Space 9 aboard the Starship Yellowstone. Melora, an Elaysian, has initial difficulty adjusting to the one-gee gravity field on the station, but quickly demonstrates that she will not allow this challenge to compromise her performance as a Starfleet officer. She befriends Chief Medical Officer Julian Bashir, and the two become romantically involved.
Fallit Kot, an old associate of Quark’s, visits Deep Space 9, intending to exact revenge on Quark for a business deal that went bad eight years ago. Kot kidnaps Quark and takes other hostages, but is apprehended as he attempts to escape into the Gamma Quadrant.
• Nurse Alyssa Ogawa becomes romantically involved with Ensign Markson, a fellow Enterprise -D crew member.
Prior to “Attached” (TNG). This is presumably before her involvement with Lieutenant Powell in “Lower Decks” (TNG).
• Commander Will Riker visits station Deep Space 9, where he meets Jadzia Dax at Quark’s bar. Riker earns a reputation as a good dabo player.
“Defiant” (DS9). Dax said she’d met Riker a year before the episode, the seventh of the third season.
Editors’ Note: It seems possible that Dax may have been referring to the Enterprise -D’s visit in “Birthright, Part I” (TNG), but that would have been aboout two years before “Defiant” (DS9).
• The U.S.S. Enterprise -D travels to planet Kesprytt III in order to evaluate a request by the Kes government for associate membership in the United Federation of Planets. It is an unusual request in that Kesprytt III does not yet have a unified world government, normally a condition for membership in the Federation.
Prior to “Attached” (TNG).
~1:[2,#B],5:[1,#I],131:[3,#I],154:[6,#I],161:[2,#I],178:[19,#I]@1“Attached” (TNG)@2Stardate 47304.2. Enterprise -D captain Jean-Luc Picard and Chief Medical Officer Beverly Crusher are abducted while beaming down on to Kesprytt III, apparently by the Prytt government. Initial diplomatic efforts by Executive Officer William Riker to work with both the Kes and the Prytt government to secure the release of both officers are unsuccessful, although their freedom is secured through covert means.
During their captivity, Picard and Crusher were both implanted with a neural control device that caused them physical discomfort if they became separated. A side-effect of these devices was a sharing of their thoughts.
• Picard and Riker both file reports to the Federation Council recommending against Federation membership for Kesprytt III because the planet’s society is not yet advanced enough to solve its internal disputes.
After “Attached” (TNG).
• Pel, an ambitious young Ferengi entrepreneur, is hired as a waiter at Quark’s bar on station Deep Space 9.
Prior to “Rules of Acquisition” (DS9).
• Starship Enterprise -D executive officer William T. Riker and Counselor Deanna Troi complete their Crew Evaluation Report.
“Lower Decks” (TNG). Three months before the episode. This would seem to make the evaluation report a quarterly ritual.
~1:[4,#B],100:[13,#I],156:[26,#I],193:[5,#I],208:[2,#I],234:[17,#I],306:[12,#I],319:[7,#I]@1“Rules of Acquisition” (DS9)@2(No stardate given). Ferengi Grand Nagus Zek returns to station Deep Space 9, offering Quark the opportunity to serve as his negotiator for Gamma Quadrant business. Quark learns that his first assignment, to negotiate the acquisition of tulaberry wine from the Dosi, is a ploy by Zek to learn about the Dominion at minimal risk to himself. The Dominion is believed to be a dominant power in the Gamma Quadrant. Quark suffers a setback in his standing with the nagus when Quark’s associate, Pel, reveals herself to be a female posing as a Ferengi male.
Editors’ note: “Rules of Acquisition” (DS9) marks the first mention of the Dominion.
• During Quark’s absence in the Gamma Quadrant for Zek, Rom is forced to break into Quark’s latinum floor vault in order to assure the safety of Quark’s profits. Rom has also been opening Quark’s storeroom using a desealing rod without Quark’s knowledge.
“Necessary Evil” (DS9). Rom wasn’t clear that his break-in occurred during “Rules of Acquisition” (DS9), but Quark did indeed visit the Gamma Quadrant during the episode.
• Pel departs station Deep Space 9 aboard an Andorian transport.
After “Rules of Acquisition” (DS9).
• Contact is lost with the Federation medical transport ship U.S.S. Fleming, last reported to be carrying a cargo of rare bio-mimetic gel through the Hekaras Corridor. A Ferengi trading vessel also passes through the region.
Four days before “Force of Nature” (TNG). The Ferengi ship passed through a week before the episode.
• Geordi La Forge borrows Data’s pet cat, Spot. La Forge told his friend, Data, that he was thinking of getting a pet cat for himself, and he wanted to experience the full range of feline behavior before making that decision. Spot is not happy in her temporary home, and Geordi proclaims the cat “untrainable.”
A couple of days before “Force of Nature” (TNG). Geordi apparently did not get a pet cat of his own.
~1:[4,#B],7:[2,#I],15:[2,#I],37:[1,#I],197:[13,#I],237:[20,#I],258:[4,#I],298:[5,#I]@1“Force of Nature” (TNG)@2Stardate 47310.2. Starship Enterprise -D investigates the disappearance of the U.S.S. Fleming somewhere in the Hekaras Corridor, a region of space characterized by unusually intense tetryon fields. It is learned that the Fleming, and other vehicles disabled in the area, were disabled by Hekaran scientists who sought to gain the attention of the Federation to their findings that the continued use of warp drive was causing serious damage to the fabric of space.
Hekaran scientist Serova sacrifices her life in a dramatic demonstration of how excessive use of warp drive in a region of space with subspace instabilities can cause a dangerous subspace rift. As a result, the Federation Council orders that all Federation spacecraft be limited to a maximum speed of warp factor 5, except in cases of extreme emergency, in order to limit further damage to the structure of space. Warp travel in areas found to be especially susceptible to damage is restricted to essential travel only.
Starfleet sets up a weather control matrix on Hekaras II to help maintain the planet’s climate, since the subspace rift in the Hekaras Corridor has already caused a shift in the planet’s orbit.
Editors’ Note: The warp speed limit remained in effect for the remainder of Star Trek: The Next Generation.
• Starfleet begins a program to develop a new warp engine design that will not cause damage to the fabric of space.
Conjecture, but they obviously succeeded in developing a new design or a modification to existing designs by the time the Voyager was launched in 2371.
• Deep Space 9 commander Ben Sisko asks security chief Odo to record a daily log of law enforcement activities aboard the station.
Quark travels to planet Bajor at the request of a woman named Pallra.
Prior to “Necessary Evil” (DS9).
~1:[3,#B],137:[24,#I],163:[2,#I],208:[4,#I]@1“Necessary Evil” (DS9)@2Stardate 47282.5. Ferengi entrepreneur Quark is severely injured while in the employ of a Bajoran woman named Pallra, seeking to obtain a list of Bajoran nationals who collaborated with the Cardassians during the occupation. Pallra had hoped to use the list for blackmail purposes, but is thwarted when her actions are discovered by security chief Odo. Also uncovered in the investigation is the fact that Kira Nerys had been responsible for the death of Pallra’s husband, Vaatrik, five years ago.
• The Dominion invades and conquers the T-Rogorans in the Gamma Quadrant, making it possible for some three million Skrreeans, who had been enslaved by the T-Rogorans, to flee. The Skrreeans hope to make a new home on the other side of the Bajoran wormhole, which they call the “Eye of the Universe.”
Several weeks prior to “Sanctuary” (DS9). Exact date is conjecture, but Skrreean refugees arrived at Deep Space 9 in the episode, several weeks hence.
• The Starship Enterprise -D travels to planet Atrea IV in response to a request for aid from the Atrean government to help prevent a natural disaster on their planet. Atrea IV’s core is cooling at a very high rate, causing a dramatic increase in seismic activity.
