Star Trek Combined Timeline

COMBINED TIMELINE OF STAR TREK HISTORY

Editing and Compilation By Alex Rosenzweig (All Years—Old Earth Calendar)

(This history is exhaustive and includes information from all series – including the animated series – and movies, which are canon, as well as the various comic books and comic strip, which are not canon, but are still interesting, and all RPG’s and Star Trek based technical documents, of which we use FASA and Last Unicorn Games as canon for the campaign. The notes in brackets [] explain the background, sources, and thought-processes for this Timeline of Star Trek History. Each listing includes the year, then any sources or deductions that led to the entry in the Timeline for that year. Where a source note says (Modified), it refers to an alteration in the date of an event in order to resolve an error or inconsistency in the timeline from which that event was drawn. By making such modifications, potentially conflicting timelines may be incorporated, resulting in a more complete picture of the Star Trek Universe. All added timeline information for the campaign are in bold and are extrapolated from references to the future in various series, the direction things were going in the movies, and from the Star Trek MMO’s history – it’s set 40 years in the future from Nemesis)

2375—The Federation reacquires the worlds traded to the Cardassians in the Federation/Cardassian Treaty and Jankata Accords of 2370, which re-drew the Federation & Cardassian borders to create a demilitarized zone. This takes place in a conference between Federation Senator Dander of Tellar and Jagul Goinn of Cardassian Home Fleet, the largest and leading Cardassian faction of the Cardassian Government that is trying to coalesce from the chaos following the Dominion War. The Federation absorbs the former demilitarized zone into itself, effectively taking back the worlds they had given to the Cardassians and keeping the worlds they had gained. In exchange, they agree to provide a “stabilizing force” in Cardassian space for the next 10 years, or until asked to leave by the yet-to-be-established Cardassian Government. Additionally, the Cardassians agreed to relinquish their claims on several worlds held by the Klingons and Cardassians that they had no realistic chance of retaking anyway, allowing the Federation to smooth things over and maintain their allied state with the Klingons and Romulans.
2375—The Voyager assists the Rhawnian vessel Traveler to survive the energy and plasma wave from the collision of their homesun with another star.

2375—Worf enters service as a Federation Ambassador to the Klingon Empire.
2375-2376—The Equinox is found by the U.S.S. Voyager. By this time, the Equinox crew has abandoned most Star Fleet principles, and is even killing aliens to use a chemical substance in their bodies to enhance the ship’s warp drive. The ship, and subsequently Voyager, come under attack by the aliens, and eventually the Equinox is destroyed. The surviving crewmembers join the Voyager and continue homeward. [“Equinox”]
2376—Getting 2 shipyards functional again, the Cardassians are able to complete the construction of 7 Galors and 3 Keldans, beginning new construction on additional ships to begin replenishing their fleets. No one realizes that these are upgraded Dominion designs at the time of their launch.
2376—Suspecting Romulan treachery, among other concerns, the Klingons redeploy the majority of their forces back to their home territories following the conclusion of the Dominion War, leaving approximately 10% of their units behind as an occupation force.
2376—The Klingon reduction in force and the unanticipated upgrade of the new ships of the Cardassian Forces have resulted in the loss of some of the worlds that the Klingon had claimed from the Cardassians as spoils of war, and resulting in a stalemate of forces. The Klingons maintain their right of conquest as victors in the conflict. The Cardassians appeal to the Federation to help them to recover their lost worlds from the Klingons, however the Federation does not chosen to directly act in this matter as they believe that to do so would strongly erode their relations with the Klingon Empire. Instead they work for a diplomatic solution, with all sides agreeing that no further conquering will take place, and the status quo will be maintained in the Cardassian territories for now.

2376—The Federation re-visits the al’Hmatti petition for aid, and sends Ambassador Worf aboard the IKS Gorkon to resolve the situation, if possible. Worf’s solution is to set up a Klingon as ceremonial emperor (upon the death of the al’Hmatti emperor), while giving the true control and power to the al’Hmatti. Both the Federation and Klingon governments accept this, ending the situation. [Diplomatic Implausibility]
2376—An additional Cardassian shipyard goes online, finishing hulls on 4 Galors and 2 Keldans. The other yards produce at the rate of 4 Galor(D)s and 2 Keldan(D)s per year. Multiple raids from Klingon forces are beaten back from all 3 shipyards by Cardassian forces. The Cardassians have inferior technology, but have heavily defended these sensitive installations. While there is damage sustained on both sides, no significant losses are reported by either combatant, and the yards are never offline for more than 3 days at most.
2376—In response to perceived predations by the species inhabiting Gemworld, an alien intelligence from another dimension attempts to destroy the artificial world. Actions by the crew of the U.S.S. Enterprise prevent the destruction, and the rebuilding of the damaged ecosystem begins. [Gemworld]

Soon after the team reaches the planet, they cease reporting back. [Abyss]
2376—The Constitution Class U.S.S. Defiant, lost over a century earlier, reappears in Tholian space. The U.S.S. Da Vinci is sent to attempt to salvage the ship. The Da Vinci’s onboard team from the Star Fleet Corps of Engineers discovers that the artifact found on Traelus II is a Tholian web generator, revealing that the Tholians had attacked the Klingon colony. Repulsing attempts to destroy the Defiant—and the evidence—by a squadron of Tholian vessels, the Da Vinci crew are able to recover the Defiant and bring the ship back to Earth. [Interphase]
2376—A rogue squadron of Jem’Hadar attack ships assaults Deep Space Nine and destroys the U.S.S. Aldebaran, raising fears of a new conflict with the Dominion. The dispatch of a squadron to the Gamma Qadrant, in response to the attack, is canceled after a Jem’Hadar soldier arrives on the station after the attack, on a mission from Odo. He will serve as an observer aboard the station. [Avatar]
2376—2 new classes of vessel, the Aerie Class Fighter Carrier, each carrying 82 Cavalier Class Fighters, and the Guardian Class Heavy Explorer/Battleship (originally called an “Assault Explorer”) are deployed to DS9. The new classes were sponsored by Federation Senator Oell of Andoria and funding was achieved only after a brutal committee battle and a close vote. As a result of these delays, the vessel finished construction too late to enter the Dominion War, but were used extensively during chaotic aftermath. Of the original 12 carriers ordered, 9 were never started, and only the 3 that were already under construction were finished and launched; The USS Audacity, The USS Hurricane, and the USS Nimitz. Only 3 of the original 12 Guardian class were constructed as well, as escorts for the carriers; the USS Guardian, the USS Sentinel, and the USS Warden. They have been most recently deployed to Romulus to assist with the evacuation efforts underway there, and were pivotal in preventing the destruction of the Federation fleet there. After the battle at Romulus proved the effectiveness and power projection capabilities of the class, the Senate agreed to fund an additional 3 carriers, with possibly the remaining 6 to be build at a later date. The ships are under construction at this time.

2376—A Dominion shipyard, referred to in communiqués as “the prize” and believed to be destroyed during the war, is found repaired and relatively functional and in the hands of the Marques. The Carrier Wasp is available and dispatched immediately from DS9 to the area with only half of her pilots onboard, the remainder having not arrived yet, and no escort vessels. The Wasp sustains heavy damage from a variety of vessels in the area who ambushed her, the few surviving crew managing to prevent the ship from exploding and securing an area with minimal life support to hole-up in until help can arrive. The USS Guardian arrives with fighter elements onboard (who were awaiting deploy aboard the USS Nimitz upon its arrival at DS9). A fleet of three Klingon cruisers and 2 Romulan warbirds are already there and a standoff is in progress between all the various arrayed forces. The Allies negotiate and in exchange for a promise to share the technology with the Klingons and Romulans, they agree to fight alongside the Guardian and leave the facility in Starfleet’s hands. Together they dispatch four Maquis built Dominion cruisers, fighting off 2 dozen Maquis frigates, beating back 2 Breen cruisers, and rescuing the USS Wasp. The area is secured with the arrival of the USS Nimitz, along with the rest of its fighter compliment and security fleet.

2376—The planet Armus IX, newly consolidated into a global coalition government, is stricken by a virulent disease brought by aliens. [Doors into Chaos]
2376—Uncertain relations between the Deltans and Carreons degenerate into near warfare. Each world prepares a squadron of vessels to attack the other, and Star Fleet sends in a squadron of their own, led by the Enterprise, to maintain the peace. [Doors into Chaos]
2376—The colony world of Europa Nova abruptly begins suffering from exposure to theta radiation emanating from some kind of antimatter waste pouring out from an unknown point of origin (later determined to be a gateway). The colony signals for help when it becomes clear that the radiation will reach lethal levels in only a few days. Personnel and vessels from Deep Space Nine respond to the distress signal. When a gateway is found allowing passage to the Jaradan homeworld, special permission is sought and received from the Jaradans to allow a certain number of Europani refugees to transfer to their world temporarily. Kira Nerys and Taran’atar travel through a gateway to the Delta Quadrant, locate the Malon export vessel dumping antimatter waste into a gateway, and stop it from doing so. Attempting to return to Deep Space Nine, Kira enters another gateway. Taran’atar, meanwhile, is able to return to the station. [Demons of Air and Darkness]
2376—In the Delta Quadrant, as it approaches a particularly hazardous region of space, Voyager encounters a series of gateways, which open and transport over 60 vessels into the space immediately surrounding the ship. Voyager shepherds a number of the vessels through the hazardous region. On the far side, as gateways begin to close, Janeway goes through one to attempt to locate some answers, and discovers Q, who ultimately aids the other ships in getting back where they came from and Voyager through the hazardous area of space. [No Man’s Land]
2376—The opening of two gateways on Aeron and Markania allows the Markanians to attack and assassinate all but one of the Aeron ruling family. The Excalibur and Trident are dispatched to attempt to deal with the situation before the Aerons can use the gateway technology to counterattack. After a series of tense negotiations, and the death of the Markanian warlord who had masterminded the initial attack, matters are brought to a tentative resolution. [Cold Wars]
2376—A group of ships is assigned to contact and investigate the alleged Iconians. Enterprise is among them. En route to the group’s staging point, Enterprise is sent to the Gorn Alliance to ask them to send a representative, along with other major powers of the galaxy. Still posing as iconians, the Petraw initially open communications with, and then subsequently attack, the ships in the combined group. The group is also joined by a ship dragged through a gateway from the far side of the galaxy, which is seeking a way home. During the conflict, Captain Picard travels through a gateway. He arrives on an Iconian outpost world, and meets a group of Iconians monitoring gateway activity. They direct him to a world on which there is a device that will enable shutdown of all the gateways. Picard locates the device, with remote relays that must be set into fourteen key gateways. Returning to the Enterprise, Picard organizes the dispatch of ships to each of the gateways, and in a cooperative action, the gateways are shut down, ending the crisis. The Petraw are told to remove themselves from known space. [Doors into Chaos/What Lay Beyond-“The Other Side”]
2376—With the dissolution of the Federation/Cardassian treaty, which was principally responsible for the dissention of the peoples of the worlds given over to the Cardassians and therefore caused the creation of the Maquis, a general amnesty is issued for all Maquis members who aren’t specifically being sought for war crimes. Prior Star Fleet Maquis personnel are welcomed back at their former ranks, thus providing an immediate gain of experienced, trained personnel that are sorely needed due to war losses. While some conflict is expected as these individuals reintegrated back into Federation society, and especially into Star Fleet, feelings are stronger than anticipated in these matters and it does not go as smoothly as hoped for.
2376—Following the transfer of the colonists from the Jaradan homeworld to Torona IV and the shutdown of the Iconian Gateways, diplomatic relations break down between the Jarada and the Federation. [Twilight]
2376—Ground blasting for a Dominion War memorial on the planet Narendra III unearths the final Malkus Artifact, which contains the disembodied life-force of Malkus the Mighty. Utilizing several persons who were exposed to the artifacts previously and were susceptible to his control, Malkus gathers the four artifacts in an attempt to regain power. Aided by an ancient (and long-lived) Zalkatian named Aidulac, Ambassadors Spock and Worf, Admiral Leonard McCoy, Captain Rovbert DeSoto, Kira Nerys, and several other officers—including the crews of the Enterprise and IKS Gorkon in planetary orbit—are able to thwart Malkus’ plan and render the artifacts inert, after which they are returned again to the Rector Institute…under heightened security. [The Brave and the Bold, Book Two]
2376—The U.S.S. Defiant is sent on an extended reconnaissance and survey mission into the Gamma Quadrant. Multiple contacts with new civilizations include the Vahni Vahltupali; the alien Inamuri, accessed through an interspatial rift created by the Prentara; the D’Naali and Nyazen races (and the alien “cathedral” artifact in a disputed area of space between them); and the warring Yrythny and Cheka species. [Mission Gamma: Twilight/This Gray Spirit/Cathedral/Lesser Evil]
2376—Formal talks are reopened on the subject of Bajor’s entry into the Federation, as well as a separate series of agreements with Cardassia. The talks with Cardassia falter, at First Minister Shakaar’s direction, but the membership agreeents are reached. Just before the agreement can be signed, however, Shakaar is assassinated by a member of the Trill dlegation on Deep Space 9. The actual entry of Bajor into the Federation is placed on hold, and an immediate investigation is begun. It is revealed that Shakaar had been occupied by one of the parasitic aliens of the species that previously tried to infiltrate Star Fleet Command, and is engaged in a conflict with the Trill symbionts. A Star Fleet vessel, the Gryphon, is sent to Trill to continue the investigation, but it is determined that one of its officers is also occupied by a parasite alien, and the ship is stopped before it can do any damage. [Cathedral/Lesser Evil]
2376—In the Gamma Quadrant, a team from the trading vesel Even Odds discovers the mechanism that releases the legendary, and long dormant, Eav’oq species. As a part of the release process, a region of space, including the Idran System, has rotated, moving planets, stars, and many other objects within the extent of the affected space. [Rising Son]
2376—En route back to the wormhole to return to the Alpha Quadrant, the Defiant discovers that the Idran System has moved. While beginning to investigate that, it encounters a Jem’Hadar vessel, piloted by another clone of the Vorta Weyoun. Among its passengers are Jake Sisko and Kai Opaka. [Lesser Evil/Rising Son]

At the same time, the ship is visited by Admiral Kathryn Janeway, who has traveled back in time from the year 2403 with advanced technology designed to counter the Borg. Admiral Janeway and Captain Janeway develop a plan to attack the Borg. The plan, involving the insertion of a computer virus into the Collective, destroys the Borg central nexus and the Queen. At the same time, the Voyager destroys the transwarp hub and connected conduit systems, using advanced transphasic torpedoes. Voyager itself, however, is able to use a conduit (and a Borg sphere) to return to Earth, before that conduit is destroyed, returning home after almost seven years in the Delta Quadrant. [“Endgame”]
2377—Birth of Miral Paris, daughter of Tom Paris and B’Elanna Torres. [“Endgame”]
End Voyager series
2378— Sethis of the Vulcan Science Academy announces a theoretical breakthrough on the STWC issue. He dumbs-down the mathematics as much as he can, and eventually a small handful of subspace physicists understand and vet the theory. In essence, there are subspace walls that interfere with STWC establishment making some of them short term, and some of them impossible. They are constantly shifting and changing as the galaxy rotates relative to the TW subspace domain, and care must be taken when conduits are created. In his presentation to the UFP Council Committee on STWC he said, “Without creating the STWC’s that are in place already and the accident that caused the loss of the USS Narsel it would not have been possible to arrive at this knowledge.” He also went on to say that all conduits that had been put up would have to be taken down and replaced before there was an accident, but that the new ones should be much safer and stable. Immediate discontinuation of the Conduit Network was ordered.
2378—Work to scan out precision STWC beginning and ending points is begun.
2379—William T. Riker and Deanna Troi are married. En route to Betazed, the Enterprise crew discover another Soong android, called B-4, on Kolarus III. [“Star Trek Nemesis”]
2379—In a surprising coup, the Romulan Senate and Praetor are assassinated. The new Praetor, Shinzon of Remus, requests to meet with a Federation envoy, and the Enterprise is diverted from its trip to Betazed and dispatched to Romulus. Upon arrival, it is discovered that Shinzon is actually a Human, a clone of Captain Picard, and he intends the destruction of both Picard and Earth. The Enterprise engages Shinzon’s vessel in battle, and is nearly destroyed, but is aided by a pair of Romulan vessels whose commanders oppose Shinzon. Shinzon attempts to activate a thalaron radiation weapon, but Lt. Commander Data destroys it and Shinzon’s vessel, at the cost of his own life. The Enterprise is towed back to Earth for repairs. [“Star Trek Nemesis”]
2379—William Riker is promoted to the rank of Captain and assigned as commanding officer of the U.S.S. Titan. Doctor Beverly Crusher is reassigned to Star Fleet Medical. Enterprise’s new executive officer is Commander Martin Madden. [“Star Trek Nemesis”]
2379—The Klingons are ill prepared for the opportunity presented to them when the Romulan Praetor and the majority of the Romulan Imperial Senate are killed (see the movie Star Trek: Nemesis for full details) and Chancellor Martok does not agree with the action, seeing it as dishonorable. However the council overwhelmingly argues to attack the Romulans in their moment of weakness “just as they would do to us”. The Klingons launch across their borders into Romulan space with all the ships they could hastily assemble, capturing 12 systems. Heavy fighting follows with several systems changing hands a few times. When peace is finally negotiated (through Federation arbitrators) 10 of these systems remained in Klingon hands.
2379 – 2382—Upset with the Federation “betrayal” for “siding with the Romulans” following the Klingon incursion of 2371, the more warlike and vocal of the Klingon influential begin to call for a war with the Federation. These few form the core of Cha’vurrl (Way of Honor) movement, and steadily gain strength to become a major political force within the Empire. Relations with the Federation deteriorate as the Cha’vurrl gain in popularity.
2380—Sethis is awarded the Cochrane Award for his work on the STWC solution.
2380-2382 Over this 2 year period all of the formerly existing STWC’s are put back in place.
2382— Chancellor Kur’gek comes to power in the Klingon Empire. Taking the reins of the Empire in 2382 following a dual with Chancellor Martok (and killing him), Kur’gek is a war hero of the Dominion War and a champion of the Cha’vurrl ideals. In his commencement speech, Kur’gek is quoted, “The natural state of the warrior is combat. We are a race of warriors, therefore the natural state of our race is war. When Klingons stray onto the path of peace we deny our nature, we deny that which makes us Klingon. We shall return to the way of the true warrior, and the essence of the warrior race.”
2383—Klingon ambassadors approached Federation representatives to discuss the possibility of a joint assault on the Romulan Star Empire and the remnants of the Cardassian Union, beginning the consolidation of the Alpha Quadrant between the “two great powers” of the Quadrant. The Federation, declines.
2383 – 2387—At the beginning of his rule, Kur’gek holds a tenuous grip on power, but consolidates his power considerably through family entanglements, bribes, assignations, scapegoats, marriages, individual advancement, and every other trick in the book. By the time of the Romulan incursion Kur’gek has an almost unanimous lock on his council, over 60% of the populace are counted among the Cah’vurrl Loyalists, and his followers are fanatical.
2383—STWC created between Denobula and Tellar, Tellar and Sol.
2384—STWC created between Starbase 74 and Coridan, Coridan and Risa.
2385—Commander Worf resigns his ambassadorship and returns to Starfleet. He is promoted to Captain and assumes command of DS9.
2385—STWC created between Coridan and Rigel, Rigel and Regulus.
2386—The Cardassians file a formal grievance with the Federation asking for support in policing their territories. The Cardassians are dealing with an enormous black market issue supported by active piracy, Ferengi and Orion profiteering, and increasing aggression from the Klingons in the area. Additionally, the Breen are beginning to put military pressure on the fledgling government forcing them to defend their border. They simply don’t have the ships to handle the situation, and are requesting the Federation’s help to prevent exploitation and help them to curb the activities of the pirates, Ferengi, and Klingons until their forces have been replenished to a point where they can take over these duties themselves. The Federation Council agree, seeing an opportunity to create strong relations with a powerful neighbor and a chance to shut down the illegal activities that are beginning to spill over into Federation territories. As relations deteriorate with the Klingon Empire, the Federation is less concerned with supporting the Empire’s interests in the Cardassian Territories, which prevented them from taking such an active role in the past.
2386—Admiral Koderman is given orders to form a peacekeeping force and deploy to Cardassian space with all due haste. A crash ship refit program is enacted to create the fleet needed to support this effort, and the ranks of Star Fleet are scraped to come up with the personnel to man the fleets, many of these receiving promotions well ahead of normal advancement cycles.
2386—STWC built from Cardassia to Bajor, Bajor to Trill, at last completing link to Federation STWC network.
2386—Admiral Janeway retires. Commander Chakotay, at Janeway’s request, is skinned and turned into a throw rug for her living room. No one attends his funeral.
2386—Crime and piracy are down throughout Cardassian space after the arrival of Admiral Koderman’s forces. Disquieting reports of how this is achieved begin to be received at Koderman’s command HQ. Most unsettling is the quiet approval of the methods used by the Cardassian liaison assigned to Koderman. An investigation of the entire command structure is launched.
2387—A record number of courts martial hearings take place within Starfleet. Many of these are former Maquis personnel, and the majority of the influx is from the rapidly advanced personnel in Admiral Koderman’s command. Charges range from incompetence to mass murder (from orbital bombardment). Courts martial rates return to normal after the first group of personnel is evaluated and positioned to suitable positions within the Fleet.
2387—Spock travels to the Hobus star (in binary orbit with the Romulan star) in an experimental ship in an attempt to halt the Hobus star from going supernova and is never heard from again.
2387—Hobus star goes supernova, Romulus and Remus will be destroyed within 7 months.
2387—2 days after the Hobus star supernovas, at the request of the Romulans and with the strongest possible backing by the Vulcans, the Federation launches a strong relief effort to the Romulus/Remus homeworlds. Ships are sent to help evacuate the population, biosphere, works of art and cultural treasures, and other essentials that can be rescued before the Hobus supernova reaches and destroys these worlds. All of the Starfleet assault ship and transport fleet, 10% of the Federation transport fleet, and a contingent of 25 cruisers are sent to the Romulans aid. The ships assemble and arrive at Romulus within 1 month of the Romulan request, approximately five and a half months before the arrival of the supernova.
2387—An emergency STWC is established between Sol and Bolarus, even though it is considered risky. This STWC is essential to moving ships rapidly to the area to support the Romulas evacuation. A permanent corridor is eventually calculated, along with one from Bolaris to Starbase 241. A long range experimental STWC is created and successful linking Nimbus to Starbase 105, though it tests the limits of the theory.
2387—The Romulans begin evacuating their government, VIP’s, etc to establish a new seat of government on Romii, a system far enough away to avoid negative effects from the Hobus supernova, yet only half a day (12 hours) away at Warp 7. This allows most transports to make a trip a day with refugees and materials. Based on the amount that can be hauled on average, the turnaround time on average, and the time available, the Romulans estimate that they require the continuous use of approximately 220,000 vessels to complete the evacuation of Romulus, and another 170,000 vessels to evacuate Remus. Realizing that it’s simply not possible to accomplish much in the way of evacuation, All underground complexes, mines, etc begin rapid conversion into emergency shelters and new shelters are constructed as rapidly as possible. They are supplies as best they can be using all available foodstuffs and every available replicator. Even so, only a third of the population of Romulas can be saved when the supernova arrives. Ironically, the much more heavily Remus will be able to save nearly 60% of its population. The question of how long the populations can hold out underground before being resettled remains unknown. Lotteries are held to determine which families enter the shelters.
2387—Alerted by their intelligence operatives, the Klingons begin to quietly mass along the shared Romulan border, using cloaking technology and natural features to keep their forces hidden. Simultaneously, they refit many older and mothballed ships with transponders mimicking the vessels they moved towards Romulan space, and these ships are moved about in Klingon space, simulating normal operations of the Klingon fleet. Discrepancies are noticed, both by the Federation and Romulans, but the meaning was isn’t realized immediately.
2387—Klingons launch a full assault across the Romulan boarder two and a half months after the Hobus star supernovas, overwhelming border defenses and driving deeply into Romulan territory. Fully 50% of all Klingon forces are committed to this attack, with 20% of remaining forces in reserve along the Romulan boarder, 10% in their Cardassian territories, leaving only 20% of forces to take care of the rest of the Empire’s needs. It is an all out, all or nothing attack. Within 3 days of launching, forces begin arriving in the Romulus/Remus system and attack any ship they see, including the transport ships of the Federation, Vulcans, and many other worlds. Romulan forces, assisted with a light contingent of Federation capital ships, most notably the 3 Federation carriers, fight the Klingons to a standstill allowing the remaining non-combat vessels to flee, but only after losing roughly one third of all transport ships.
2387—The Romulan Ambassador to the Federation, , accompanied by Federation representative from Vulcan, , speaks directly to the Federation council requesting the Federations further assistance in the evacuation of their homeworlds, and a military alliance to help them repel the Klingons from their borders and restore the balance of power within the quadrant. Among promises of friendship and long lasting peace resulting from much stronger relations with the Romulans, the Ambassador mentions the threat that a Klingon Empire who has consolidated Romulan space represents to the Federation and that they cannot afford to allow this to happen for their own best interests. The ambassador’s comments reflect the issues that the council had already been debating. The Vulcans call in every favor they have, pull every string, and through their full weight behind the Ambassador’s request. The Federation president, Al Dente, agrees to take the matter seriously and will get back to the Ambassador with a response with “all due haste”. After 2 weeks of bitter debate nothing has been firmly decided yet regarding an alliance against the Klingons, but a commitment of Starfleet vessels to protect the unarmed ships and to assist with the evacuation of the planet passes unamiously.
2387—With tension rising along the Klingon/Federation boarder following the Klingon’s surprise invasion of Romulan space and declaration of war, Starfleet deploys additional strength to Starbase 34, Starbase 234, Starbase 133, Deep Space K-7, Starbase 82, Boradis, Starbase 105, Starbase 117, Starbase 123, and Starbase 152. While not ideal defensive positions, these do represent significant “Strikeback” positions should the Klingons declare war on the Federation.
2387—Now.
