Memory Beta, non-canon Star Trek Wiki
For the mirror universe counterpart, see Elias Vaughn (mirror).

Captain Elias A. Vaughn (24 October 2274-September 2383) was a Starfleet officer who served for more than eight decades in a variety of branches, including Starfleet Intelligence, Special Operations and Tactical. Despite his relativity low rank (retained in order to maintain a low profile), Vaughn was on a first name basis with most of the Admiralty and had a higher security clearance than some.


Vaughn was a critical player in several crucial events in Starfleet history, including the Tomed Incident, the Betreka Nebula Incident, the disaster at Arvada III, the civil war on Beta VI, the liberation of Betazed from the Dominion, and the Borg Invasion of 2381.

Then, after a chance encounter with the Bajoran Orb of Memory, Vaughn decided to pursue his lost dream of being an explorer. After taking the vacant First Officer's position at Federation starbase Deep Space 9 at age 101, Elias Vaughn commanded the USS Defiant on a three-month mission of exploration in the Gamma Quadrant and continued to contribute to Starfleet. He would eventually rise to command DS9 for a period before accepting command of the USS James T. Kirk. Seriously injured during the Borg invasion and left in a comatose state for two years, Vaughn finally succumbed to his injuries late in 2383, at the age of 109.

Early life

Elias Vaughn was born Saturday, October 24, 2274, and was raised on the planet Berengaria VII. He was taught about the stars by his mother, which fueled his early passion for exploration. Vaughn's mother died early in his life of Burkhardt's disease. (DS9 novel: Avatar, Book One, TNG novel: The Battle of Betazed)

On Berengaria, Vaughn was once attacked by a species of animal known as Draco Berengarius. The creature penetrated into the back of Vaughn's skull, causing some slight brain damage and leaving behind its own DNA traces and a scar running from his neck to his left ear. (DS9 novel: Bajor: Fragments and Omens)

Vaughn had a dog as a child. (DS9 novel: Avatar, Book One)

Vaughn's uncle owned a farm where bison-like cattle were raised. (ST novel: Cast No Shadow)

Vaughn joined Starfleet Academy in the year 2293 following the Khitomer Conference and the signing of the Khitomer Accords, and discovered that he had a talent for intelligence and tactical operations. Vaughn gave up his dreams of exploration for a career in Starfleet Intelligence. (TOS movie, novelization & comic adaptation: Star Trek VI: The Undiscovered Country; DS9 novel: Abyss)

Starfleet operations

Most of the first ten years of Vaughn's service to Starfleet Intelligence was spent behind a desk, analyzing data and writing reports. The few times he did manage to get into the field his assignments included shadowing a Benzite engineer eventually found innocent of trading stolen technology, and the infiltration of a Tellarite mining facility. (TLE novel: Serpents Among the Ruins)

At the age of 24 he was charged with the recovery of a container with a stolen Linellian fluid effigy inside. Before returning the vessel to the embassy he experienced a vision, one of the most peaceful experiences he ever knew. (DS9 novel: Avatar, Book One)

In 2300, Vaughn was working in the "Jigsaw department" at Starfleet Intelligence, part of a group of intelligence analysts. He disobeyed orders from his commander to follow up what had been dismissed as a redundant lead, resulting in him going into the field to help resolve a crisis on the Federation/Klingon border caused by Romulan-funded Kriosian terrorists, with Vaughn's investigation aided by former Cartwright conspirator Valeris. After the mission was completed, Malla Tancreda of Section 31 attempted to recruit Vaughn in the organization, although Vaughn refused the offer, correctly guessing that they were only making the offer to him now because he was about to get an offer for an official position the next day. (ST novel: Cast No Shadow)


After a decade of desk-bound analysis with Starfleet special operations, Vaughn, holding the rank of lieutenant, was sent on his first major official field assignment in the year 2311. He was to accompany Captain John Harriman and Commander Drysi Gravenor, a woman he thought of as a mentor, on a mission to capture the Romulan flagship, the Tomed.

Vaughn's responsibility during the Tomed mission was to steal a shuttle for the three operatives to escape in. Vaughn was nearly killed when the shuttlebay was decompressed, and later had to fight Renka Linavil inside the shuttle. He was later somewhat distraught that he was forced to kill her.

Following the successful completion of the mission, Vaughn was one one of only a handful of people who knew the full truth about the events that became known as the Tomed Incident. (TLE novel: Serpents Among the Ruins)

In the year 2319, Vaughn first partnered with T'Prynn of Vulcan and the two formed a loose partnership that lasted off and on for thirty years. (DS9 novel: Lesser Evil)

The Betreka Nebula Incident

In 2328, the Cardassian Union and Klingon Empire threatened to go to war over the planet Raknal V near the Betreka Nebula. The Cardassians claimed the world as their own, but the Klingons disputed the claim after the remains of the vessel of the legendary Klingon Captain Ch'gran were discovered on the surface. The Klingons, who wished to recover the legendary hero's vessel, argued that the presence of Ch'gran's ship on the planet constituted a prior claim to the planet.

Vaughn was assigned to the Starfleet-hosted arbitration delegation for the dispute aboard the USS Carthage. Federation Ambassador Curzon Dax arranged an agreement between the two powers wherein whichever government could best develop the world's resources would ultimately take the planet. Vaughn was very skeptical about this plan, and said so. His skepticism was proved out as the so-called "Betreka Nebula Incident" stretched out for eighteen years with few tangible results.

It was aboard the Carthage that Vaughn first met the ship's science officer Lieutenant Ian Andrew Troi, with whom he began a long friendship. Vaughn would eventually be introduced to Troi's wife Lwaxana, and children, Kestra and Deanna. He attended Kestra's funeral on Betazed in 2336. (TLE novel: The Art of the Impossible)

Further operations

Vaughn's travels exposed him to many tragedies; Verillian children orphaned by war, the hopelessness of a Lethean veteran asylum and the genocidal holocaust on Arvada III.

The TNG novel: Death in Winter established 2339 as the date for the Arvada III tragedy, however it also established the tragedy as a plague outbreak, which may either be inconsistent with what Vaughn experienced or indicate another period of strife on the world which Vaughn was involved with, or this may have been the means of genocide.

Vaughn's mission also brought frustration, he was unable to do anything as he witnessed the deaths of eleven thousand men in the civil war on Beta VI and could not have foreseen the assassination of an Elaysian governor. (DS9 novel: Avatar, Book One)

In 2343, Vaughn first met Starfleet Captain Jean-Luc Picard of the USS Stargazer. The two would meet several times over the ensuing years, including during a coup d'état on Darnak VII. (TLE novel: The Art of the Impossible; ST comic: "Divided We Fall")

In late 2343, after Vaughn's promotion to Lieutenant Commander, Vaughn and T'Prynn retrieved Special Emissary Raisa Tartovsky from the planet Devniad as the Cardassian Union annexed the planet. Tartovsky was uncooperative, believing Vaughn to be a disguised Cardassian, forcing Vaughn to stun her and carry her back to his ship. Vaughn delivered Tartovsky to Starbase 47, where he reported to his superior in Starfleet Intelligence, Captain Uhura.

Uhura ordered Vaughn to return to Raknal V and give her his assessment of the situation there. Vaughn returned to Raknal V on the Carthage, and he and Ian Troi went down to the planet's surface together. Vaughn and Troi became trapped as a building collapsed on them due to Romulan sabotage. All evidence of the Romulan involvement was destroyed and Ian Troi died from his injuries.

Vaughn was severely injured and spent several months in recovery. After returning to duty, he tracked down Dax on Risa and informed him of the Romulan involvement at Raknal V. The two pooled their resources and discovered the truth about Ch'gran, thus convincing Klingon Chancellor K'mpec to cede the planet to Cardassia, finally ending the "Betreka Nebula Incident". (TLE novel: The Art of the Impossible)

At some point in his career Vaughn designed part of the curriculum for Starfleet's Advanced Tactical Training course. (DS9 novel: Avatar, Book Two)

Ruriko Tenmei

In 2347, following the Khitomer Massacre, Vaughn and T'Prynn met rival SI agent Ruriko Tenmei on the planet Kora II in Cardassian space. Vaughn and Tenmei were familiar with each other through their impressive after-action reports, and considered each other rivals. (TNG episode: "Sins of the Father"; TLE novel: The Art of the Impossible)

Vaughn and T'Prynn were tasked with assisting in the defection of Cardassian scientist Cren Veruda, the developer of an artificial intelligence that would give Cardassia a significant tactical advantage over the Federation.

The mission went bad, and Vaughn found himself captured and brought to a glinn named Madred for interrogation. Vaughn was rescued by Tenmei who was on the scene undercover as an agent of the Obsidian Order named Kree Omiturin (An amalgam of "Ruriko Tenmei"). After being freed by Tenmei, the pair of S.I. agents freed Veruda from his confinement and managed to disable Veruda's A.I. system.

Vaughn found himself irritated not only by the fact that he met his chief rival as she rescued him from an operation gone bad, but also by the fact that he found himself attracted to Tenmei.

Tenmei worked with Vaughn and T'Prynn frequently after that, and both were present when T'Prynn was tragically killed in a transporter accident aboard the USS T'Plana-Hath in 2349. Following T'Prynn's funeral on Vulcan, Vaughn and Tenmei began a romantic relationship.

In 2350, the two had a daughter, Prynn Tenmei, named in honor of their late colleague. While Tenmei took a leave of absence from SI to raise her daughter, Vaughn continued to be heavily involved in intelligence matters, to the detriment of his family life. In one instance, Vaughn was called away from his daughter's fifth birthday celebration by Admiral Presley to deal with a coup on Gemworld, the Elaysian homeworld. (DS9 novel: Lesser Evil)

Bajor, the Gateway and the Borg

In 2365, while working a mission specialist gathering and analyzing intelligence from the Federation/Cardassian border, the ship Vaughn was working on was contacted by a Cardassian dissident named Gaten Russol, who hoped to change Cardassia's policy toward other worlds, including Bajor and the disputed border colonies. Although Vaughn was ordered by Admiral Alynna Nechayev not to directly involve himself in the Bajoran situation, Nechayev nevertheless re-assigned Vaughn to Starbase 375, and ordered him to regain contact with Russol and establish a dialogue with him. (DS9 novel: Dawn of the Eagles)

In 2367, following the incursion with the Borg, Vaughn took part in a classified mission to Alexandra's Planet involving Romulans and an Iconian gateway. No other details of this operation have been released to the general public, although certain Starship captains, including Jean-Luc Picard, viewed the case-file during the Gateways Crisis of 2376. (TNG episode: "The Best of Both Worlds"; DS9 novel: Demons of Air and Darkness)

In 2368, following the Klingon Civil War, Vaughn was assigned to Starbase 621, analyzing starship movement along the Tzenkethi border, when he was again contacted by Gaten Russol, with whom which Vaughn had maintained sporadic contact. Russol informed Vaughn that the Cardassian prefect on Bajor, Gul Skrain Dukat, was about to make a fraudulent offer of peace and withdrawal to the Bajoran people in exchange for the Bajoran Resistance movement standing down and ceasing hostilities. (TNG episode: "Redemption")

Russol explained that Dukat's position in regards to the Bajoran resistance had grown desperate, and if the Bajorans really wanted the Cardassians to leave Bajor, now was the time to push their efforts. Vaughn passed this information on to the Bajoran refugee Keeve Falor at the Valo II re-settlement camp following the Solarion IV affair. Falor then passed the information on to the resistance on Bajor, who made their final push against the Cardassians, finally driving them out of Bajoran space. (TNG episode: "Ensign Ro"; DS9 novel: Dawn of the Eagles)

In 2369, after Vaughn was promoted to Commander and Benjamin Sisko took command of Deep Space 9, a rogue copy of Crem Veruda's AI software matrix re-constituted itself on the planet Uridi'si. Vaughn and Ruriko Tenmei (who had just returned to active duty after 19 years) were sent on the T-Plana-Hath to deal with the A.I. as they had before. (DS9 episode & novelization: Emissary)

The T'Plana-Hath and the USS Valkyrie arrived at Uridi'si just as a Borg cube summoned by the A.I. arrived on the scene. The A.I. believed itself to be sophisticated enough to assimilate the Borg rather than be assimilated by them. After a pitched battle that left the T'Plana-Hath crippled and forced the Valkyrie to retreat, the Borg ship linked with the planet-side computer where the A.I. resided, and uploaded the A.I.

As Tenmei was the only officer aboard with enough experience with the A.I. to take it out, Vaughn was forced to send Ruriko Tenmei and the Valkyrie on a one-way mission to the Borg ship to ensure that the A.I. was destroyed.

Ruriko Tenmei was successful in her efforts in destroying the cube and the A.I., but was presumed killed in action. Prynn, who was at Starfleet Academy at the time, blamed Vaughn for her mother's death. (DS9 novel: Lesser Evil)

The Dominion War

In 2375, following the murder of Jadzia Dax, Vaughn was aboard the USS Nautilus as it, along with the Twelfth Fleet, prepared to liberate Betazed from Dominion control. This offensive was preempted when the Dominion attacked the Fleet at Starbase 19. However, during this battle, Vaughn received a message from the Betazed resistance proposing a new plan to overthrow the Dominion occupiers, which Vaughn then put into motion. (DS9 episode: "Tears of the Prophets")

Working with the crew of the USS Enterprise-E (including Deanna Troi the daughter of his deceased friend Ian Troi), Vaughn infiltrated Dominion-occupied Betazed, and freed murderer Hent Tevren from custody. Tevren knew of long-forgotten lethal mental techniques that the Betazed resistance could use against the Jem'Hadar. Although Tevren was killed during the escape, Troi learned enough from Tevren to teach the resistance how to defeat the Jem'Hadar by overloading their empathic centers, which shut down the soldiers minds. (TNG novel: The Battle of Betazed)

The War also saw Vaughn visiting Panora and witnessing the destruction of Jem'Hadar vessels over Tiburon. (DS9 novel: Avatar, Book One)

At some point in Vaughn's career he became aware of the rogue agency that called itself Section 31, a secretive organization which dealt in black ops and the kind of activities that went against everything that the Federation stood for. Vaughn joined a small cabal of Starfleet officers who had dedicated themselves to the destruction of Section 31. In 2375, this cabal obtained an illegal holoship used in a failed Section 31 operation in the Briar Patch following the affair between the Ba'ku and the Son'a. (TNG movie & novelization: Star Trek: Insurrection; DS9 novel: Abyss)

Deep Space 9

Re-discovery of dreams and purpose

Vaughn discovering the Orb of Memory in 2376

In April of 2376, Vaughn was sent to search the Badlands with the USS Enterprise-E in response to a rumored Breen presence. At the time the war weary Vaughn was considering retirement. He confided in Captain Picard who suggested Vaughn would not be happy sitting back and letting worlds go by and suggested he turned to writing or teaching.

Shortly after the Enterprise found a wrecked Cardassian freighter, the Kamal, within which Vaughn discovered one of the missing Bajoran Orbs. The Orb, the Orb of Memory, flooded Vaughn's mind with long-forgotten memories and dreams of his youth, reminding him of his long-lost dream of being an explorer.

One memory that was not his was of the final moments of the Bajorans and Cardassians who died on the Kamal years earlier. In this vision, he also saw a man that he had never met, who he later identified as missing Starfleet captain, Benjamin Sisko.

Vaughn began to re-evaluate his life and career at that point. He became determined to live life for the moment, to enjoy it, even if that meant leaving Starfleet if they wouldn't agree to his wishes.

Upon arrival at DS9, and Captain Picard returning the Orb of Memory to to Bajoran Colonel Kira Nerys, Vaughn assisted Kira and station personnel in saving the station when the rogue Jem'Hadar soldier Kitana'klan sabotaged the station's fusion core.

Elias Vaughn in April 2376

Vaughn later met with Kira, and told her of his experience with the Orb. Vaughn was astonished to discover that Kira had experienced the same vision of the Kamal and Sisko as Vaughn had. With that, Vaughn put in the request to leave SI behind, and fill the vacant first officer's position on Deep Space 9.

At first, Vaughn's superiors were reluctant to grant him his request. But after Vaughn threatened to resign from Starfleet if they did not agree, they gave in, not wanting to lose a man of Vaughn's experience and knowledge. (DS9 novels: Avatar, Book One, Avatar, Book Two)

New challenges

Two weeks later, using the 'holo-ship' acquired the previous year, Vaughn assisted in the covert removal of the displaced Ingavi from the planet Sindorin, who had lived on Sindorin ever since the Cardassian Union annexed their homeword of Ingav decades earlier. Section 31 attempted to breed their own Jem'Hadar soldiers at lab located on the Badlands based world using the expertise of genetically enhanced scientist Ethan Locken. The situation grew out of Section 31's control when Locken betrayed them and established his own agenda. Section 31 informed the genetically-enhanced Dr. Julian Bashir of DS9 of the situation, hoping that the Doctor could clean up their mess for them. Following the operation, Vaughn recruited Dr. Bashir into the secret cabal of officers that wage the secret battle against Section 31. (DS9 novel: Abyss)

During the Gateway crisis in May, Vaughn commanded the USS Defiant during Starfleet's evacuation efforts at the planet Europa Nova after a lethal radiation coming from a gateway leading to the Delta Quadrant infected the planet's atmosphere. He later negotiated with the xenophobic Jarada for temporary use of their territory for displaced Europani refugees. (DS9 novel: Demons of Air and Darkness)

Vaughn in command of the Defiant

Lieutenant Ezri Dax, Vaughn's first officer on the Defiant (and one of the successors to Curzon Dax), became drawn into events when rejected host-candidate Verad Kalon unleashed a virus designed to kill all Trill symbionts and start a civil war on Trill in a misguided attempt to "free" Trill from an imagined symbiont dictatorship. Colonel Kira sent Vaughn and the Defiant to assist Dax and the Trill government in any way they could. Vaughn and the crew of the Defiant worked along with the crew of the Enterprise to thwart Kalon's scheme and deal with the civil unrest that followed. (DS9 comic: "Divided We Fall")

Gamma Quadrant exploration

Vaughn later commanded the USS Defiant on a three month mission of exploration in the Gamma Quadrant. Vaughn's daughter Prynn had been assigned to the Defiant as Conn officer prior to Vaughn's arrival at the station, and before departing on the mission, Vaughn made it clear to Prynn that her personal feelings about him notwithstanding, she would have to treat him with the respect due a superior officer if she wanted to participate in the mission.

Vaughn and Prynn had a more personal reunion after Vaughn had a near-death experience on an un-named world in the Gamma quadrant that helped to release a lifeform known as the Inamuri into this plane of existence, and saved the world of the Vahni Vahltupali from destruction. The reality of almost losing her father made Prynn realize how much Vaughn meant to her, and the two began to heal their wounds together. (DS9 novel: Twilight)

The reconciliation was short-lived, however, as the Defiant soon discovered a crashed Borg vessel, the assimilated USS Valkyrie, in the Gamma Quadrant and an assimilated and still-alive Ruriko Tenmei within. Vaughn brought Ruriko back to the Defiant, hoping that her humanity could be restored. When the Assimilation imperative proved too strong for Ruriko to resist, Vaughn was forced to kill her in order to prevent her from assimilating Prynn, her own daughter. Prynn, not believing that her mother would have assimilated her, once again blamed Vaughn for her mother's death, and once again stopped speaking to him. (DS9 novel: Lesser Evil)

Other notable incidents of the expedition included the aversion of a genocidal civil war on the homeworld of the Yrythny, and an encounter with an ancient space-born artifact that had trans-temporal repercussions for several of his crew. (DS9 novels: This Gray Spirit, Cathedral)

Upon returning to the Gamma Quadrant end of the Bajoran wormhole, Vaughn and the Defiant arrived in the aftermath of the seemingly impossible: The closest star, Idran, had moved three light-years closer to the wormhole. The species native to Idran, the Eav'oq, shared a link to the Bajoran Prophets similar to the one possessed by the Bajoran people. (DS9 novels: Lesser Evil, Rising Son)

During the Gamma Quadrant expedition, Vaughn commanded the Defiant through eleven direct first contacts, exchanged sub-space friendship messages with sixteen other species, recorded or obtained 644 new types of life, and (with the help of probes) mapped over 1200 cubic light-years of space. (DS9 novel: Lesser Evil)

Return to the Alpha Quadrant

After returning to the Alpha Quadrant, Vaughn was despondent over the renewed loss of both his wife and daughter, and sought the counsel of former Bajoran Kai Opaka Sulan at the monastery at Ashalla. Vaughn had met the former Kai during the Gamma Quadrant mission, and then at her request happily agreed to return her home to Bajor. (DS9 novels: Lesser Evil, Unity)

Agreeing to help Vaughn, Opaka exposed him to another Orb, this time the Orb of Unity. During the encounter, the temple was seized by parasite infected monks who hoped to take over Bajor for their own purposes. This left Vaughn trapped in his own orb experience, in which he came to terms with his grief in a prophet created simulation of a mental institution in Earth's 1950s. During his orb experience, he met Captain Benjamin Sisko during his own sojourn with the Bajoran Prophets. Together, Vaughn and Sisko sought to leave the celestial temple behind, and return to linear existence.

With the assistance of Kira Nerys, who had flung open the arks of all of the Orbs at once in a confrontation with the alien queen parasite, Vaughn and Sisko returned to Bajor just in time to deal with the parasite threat. (DS9 novel: Unity)

After returning to the linear plane with Sisko, Vaughn approached Prynn, not wanting to be separated from her again for any reason. Prynn agreed to accompany Vaughn to induction of Bajor into the United Federation of Planets, but despite this promising start Prynn remained distant from Vaughn, canceling three separate dinner dates with her father over the next several months. (DS9 novels: Unity, Warpath)

After the induction of Bajor into the United Federation of Planets, Vaughn assisted with the integration of Bajor's militia into Starfleet by conducting interviews and making evaluations. Vaughn, during that time, celebrated his 102nd birthday. (DS9 novel: Bajor: Fragments and Omens)

Taran'atar and the mirror universe

In early 2377, after the mind-controlled Taran'atar brutally attacked Captain Kira and Lieutenant Ro Laren, Taran'tar hijacked the runabout USS Euphrates and took Prynn hostage.

Vaughn immediately went in pursuit of Taran'atar in the Defiant, eventually catching up to him on the former Cardassian world of Harkoum. Upon locating Taran'atar, the two played a game of cat and mouse through the abandoned Obsidian Order prison known as Grennokar - a game that Vaughn lost.

Fortunately for Vaughn, Prynn had escaped from her confinement, found a weapon, and had caught up to Taran'atar and Vaughn. Before Prynn could incapacitate Taran'atar (or vice-versa), Taran'atar was transported out of the prison by the Intendant of the mirror universe (who had believed Taran'tar to be an ally).

Vaughn and Prynn were rescued from the exploding prison by a Cardassian woman who appeared to be the Mirror Universe's version of Iliana Ghemor. (DS9 novel: Warpath)

After returning from Harkorum, Captain Kira relieved him from duty because she thought he made going after Taran'atar personal. After Sisko talked to Kira and he talked to Vaughn, she reinstated him and ordered him to ops to talk to the Terran Rebellion with the senior staff. He offered and accepted to go with Kira to the mirror-Bajor to stop Ghemor. (DS9 novel: Fearful Symmetry)

The Borg invasion

Sometime before 2379, Vaughn was promoted to captain and commanded Deep Space 9, before accepting a reassignment to the USS James T. Kirk on a deep space assignment. His ship was called into service during the Borg Invasion of 2381 as part of a task force led by Benjamin Sisko, commanding the USS New York, defending the planet Alonis. Vaughn was severely injured in an attack and taken to Deep Space 9 for treatment by Doctor Julian Bashir. Sisko personally relayed a message to Prynn Tenmei regarding her father's condition.

Bashir was unable to revive the captain and as of August 2382, Captain Vaughn was still in a coma. His attending doctor, Julian Bashir, considered his prospects for recovery dim. Prynn, who remained at his bedside during his treatment, ultimately acceded to Doctor Bashir's recommendations that she deactivate the life support system keeping Vaughn alive. Vaughn was found to be able to breathe on his own. (ST - Typhon Pact novels: Zero Sum Game, Rough Beasts of Empire)

As of August 2383 Captain Vaughn had still shown no improvement in his condition. Having come to terms with her father's condition, Prynn accepted an offer from Kira Nerys to allow her father to move to a hospice on Bajor. (ST - Typhon Pact novel: Plagues of Night)

By September of that year, Vaughn had been moved to the hospice at the Vanadwan Monastery, where Prynn had agreed to allow her father to die naturally, without any medical aids. In due course, many of Vaughn's friends and colleagues came to sit by his bedside to read passages from several forms of literature; Benjamin Sisko read Ulysses by Lord Alfred Tennyson. (ST - Typhon Pact novel: Raise the Dawn)

Alternate realities

In an alternate timeline in which the Federation had been conquered by the Klingon Empire following the outbreak of war after the Khitomer Accords were not successfully signed, Elias Vaughn had become a member of the Terran resistance on Earth. Vaughn was considered an "in-the-shadows" operator by Jean-Luc Picard. By the 2360s, he had taken his people underground in response to the Klingon's starting to use carpet bombing tactics. Around then members of Picard's cell considered approaching Vaughn's group after they took heavy losses, but as Vaughn and his group were at the time in hiding, and due to Vaughn's less direct tactics, Picard considered it an unlikely prospect. (TNG - The Last Generation comic: "Inevitability")

In September 2376, during his second orb experience Vaughn took on the identity of Eli Underwood, a patient at the same insane asylum as Benny Russell on 1950s Earth. While there he interacted with numerous members of the staff and other patients, all of whom were representations of his friends and family. Vaughn ended the experience when he and Benjamin Sisko returned to the real world. (DS9 novel: Unity)

In January 2377, Kira Nerys experienced a vision set in ancient Bajor where she encountered a man named Ghavun, a representation of Vaughn. (DS9 novel: Warpath)

In another alternate timeline in which Earth was a member of the Andorian-led Interstellar Union, Vaughn served in the Union's military, the Interstellar Guard, where he held the rank of Trooper. (ST - Myriad Universes novel: The Tears of Eridanus)

A promotional image of Vaughn that was featured in several 2001 Star Trek novels.

Elias Vaughn first appeared in the first novel of the Deep Space Nine relaunch series: Avatar. He was one of several major new characters introduced to the series to compensate for characters who had moved on from Deep Space 9 by the end of the television series.

Marco Palmieri commented: "The twist on this new character is that he's a much older man than we're used to seeing. The closest comparison might be the Russian captain from the film version of The Hunt for Red October. I've always thought that, given the apparent good health and longevity of Star Trek humans, having a starring character who was still sharp and active at ninety or a hundred, with all that life experience and with yet another fifty or sixty years of life to look forward to, would add something new and interesting to Star Trek's exploration of the human condition". [1]

S.D. Perry commented: "Let me say that Vaughn's been around for awhile, and he's been working for Starfleet for much of his adult life. Since humans live to be about 150 in this era of ST, a man in his late 90s, early 100s might make a very smart, very experienced character, with a lot of interesting, classified memories. When we meet him in Avatar, he's at something of a crossroad in his life and his career. He grows". [2]

From that first introduction Vaughn has appeared throughout the DS9 relaunch and made an appearance in the Star Trek: Corps of Engineers eBook Lost Time which crossed-over with Deep Space Nine. Vaughn's history prior to Deep Space 9 has also been fleshed out by appearances in several The Lost Era stories and the TNG Dominion War novel The Battle of Betazed.
