was born on 17 March 2350 in South Boston to Michael Liam ODonnell, a Senior
Engineer at the Utopia Planitia Fleet Yards, and Rhiannon Bronwyn Kierans, a Professor of
21st Century History at Harvard University.
Kieran has a older brother, Liam, (born 07/05/2348), who is now a Senior Researcher
at the Memory Alpha Research Foundation on Memory Alpha, and a younger sister, Meghan
(05/19/2353), a doctoral candidate at the Daystrom Institute, who is currently researching
the origins of the Planet killers, and their relationship to the Borg. Kieran and his sibs grew up in the relative
security and the closeness of South Boston, surrounded by family and friends.
was a good student in the South Boston school system, his teachers pushing him towards
engineering once they realized that he had a natural knack for it. He would also accompany his father to Utopia
Planitia when ever school vacations allowed, getting tours of unfinished ships, and ships
in for repairs, and even helping his father out with actual work whenever he could.
16, Kieran applied for and was accepted into the early admissions program at Star Fleet
Academy. He went into Engineering School and
applied and went to Command School as well. Besides
studying engineering, he also took language and culture courses in Klingon, Kzinti,
Vulcan, and Bajoran. Kieran also developed
some friendships, including fellow engineering cadet Molly Smithe, science cadet Pavel
Vladimir Maikov, and security cadet Jamie Stieger. The
four of them were very close throughout their four years at the Academy. They were assigned to the same team, and performed
in many of the same training missions. The
four of them did their cadet cruise together during their 3rd year of Academy,
3 months aboard the U.S.S. Tylin, an Oberth class starship that was assigned to train
cadets before they were assigned to starships. They
roomed together, and worked on Alpha shift together as cadet department heads. It was a great experience, and they returned to
Star Fleet Academy in good spirits. During a
shore leave on a frontier world of the Federation, Kieran and Molly both got data ports
surgically inserted into the base of their skulls, allowing them to directly interface
with a computer system.
the Academy, all four were assigned to the U.S.S. Republic.
Kieran stayed on the Republic for about a year with his friends before being
offered a chance to go to Star Fleet Intelligence Training back on Earth. Kieran jumped aboard a transport at Starbase
Earhart and arrived on Earth 2 days later.
spent a year at Star Fleet Intelligence Training School in Moscow, Russia, learning
infiltration techniques, and taking other courses as well, in command techniques,
engineering systems, and in Anti-Terrorism training.
While there, Kieran was able to meet Tuvok, before Voyager was sent to the Delta
Quadrant. Tuvok lectured at the SFI facility
for a week on infiltration techniques, and Kieran was able to meet with him afterwards for
lunch, and discussed various styles and techniques. When
Voyager was initially presumed lost, Kieran was saddened, because he had hoped to work
with the Vulcan someday. Kieran persevered
and graduated at the top of his class. After,
he was assigned to the USS Prokofiev, to help dismantle the Marquis threat. Kieran was a model officer, and earned two
commendations from Captain Simons for valiant service in dealing with the Marquis. After the Dominion entered, and joined forces with
the Cardassians, and wiped out the Marquis, the Prokofiev was reassigned to the front
line. Kieran stayed on the Prokofiev for
another couple of months, until May 12th, when he was transferred to the USS
Manchester, NCC-35855, one of the Steamrunner class vessels. Kieran was on the Manchester when she was
destroyed by Cardassian vessels on May 18, 2373, about 20 light years from Federation
space, just outside the old Federation/Cardassian DMZ.
Kieran just made it to an escape pod, the only survivor of the Manchester.
a week of being alone in the escape pod, Kieran was rescued by the IKC SuDqul, on a
classified mission for the Klingon Empire. Komar
HoD (Captain) reviewed what the Imperial Database had on Ensign ODonnell, and
explained to Kieran that the SuDqul was on a classified mission, and were required to
maintain strict radio silence until their returned to QonoS, and that they could not
return Kieran to the Federation, nor let anyone now that he was even alive. Komar offered Kieran a place on the SuDqul until
the mission was over. Kieran accepted and
joined the SuDqul as an engineer, and began his career in the Klingon Defense Force.
SuDqul returned from its mission in late August 2373.
By this time, Kieran was wearing the uniform of a Klingon Engineer, and had
discarded his Starfleet uniform. He had
acclimated himself to living with his new shipmates, eating Klingon food, speaking in
Klingon, and even beginning to think in Klingon. He
worked hard to make himself accepted by the other Klingons on the ship, to the point of
even following Klingon rituals. He began to assimilate Klingon culture into his life, it
complimented his personality quite well. He
learned how to use a batleth, a dktahg, and a mekleth, along with other
Klingon weapons. Even after the SuDqul
returned, Kieran did not return to the Federation, it seemed that Starfleet had forgotten
about him. He wrote to his old friends when
he could, but, besides them and his family, he never received any communications from
Starfleet. During this time, the war with the
Dominion was in full swing, which helped to explain why there was no communication from
Starfleet in regards to Kierans status. Kieran
figured that Star Fleet knew where he was, and would find him when they were ready. He learned how to use a batleth, a
dktahg, and a mekleth, along with other Klingon weapons.
continued to work hard on the SuDqul, and, when the Assistant Chief Engineer was killed in
a reactor accident during a battle with JemHadar.
After the battle, Kieran was called into Komars office, and given a field
promotion to the KDF rank of Sogh (Lieutenant) and made the Assistant Chief Engineer, for
his superior service to the SuDqul since he arrived on the ship. Kieran served well as the Assistant Chief
Engineer, dealing with problems as needed, and keeping the crew below him in line. He was respected and well liked by his fellow
shipmates. When the SuDqul made stops at
Klingon ports of call, he left ship with his fellow Klingons, and ate and drank with them,
and acted like a Klingon. He fought other
Klingons when his personal honor was insulted.
May 3rd, 2374, Kieran was brought into the House of Komar as the husband of
Komar HoDs daughter, Aryn, the SuDquls Chief Science Officer. Aryn and Kieran had began their
relationship/courtship about 8 months before, and this was the culmination of it.
served the SuDqul with honor and conviction, and was a loyal officer for Komar HoD, and,
while on board, was in command of the SuDqul numerous times, during 3rd shift. Kieran also commanded the SuDqul during combat
against enemies of the Klingon Empire, and had no qualms with doing so, giving orders and
taking responsibility with a Klingon mindset.
also tried on various occasions to contact his family and friends back in the Federation,
but, he never received any replies to his messages. Both
Kieran and Komar HoD attempted to determine the cause for this, but were unsuccessful.
(Starfleet Command presumed that someone was faking Kierans codes and ignored any
attempts at contact, and rerouted his communiqués from his family and friends, to prevent
any unnecessary heartbreak. It wasnt
until March of 2376 that Starfleet confirmed
that Kieran was alive and working as an Engineer in the Klingon Defense Force, and began
the necessary paperwork to return Kieran home.)
of Kierans efforts, the SuDqul had one of the lowest maintenance rates in the
Klingon Fleet. This process began when he
became the Assistant Chief Engineer, and he made sure that the ship was kept in top
condition. Some of Kierans techniques
have been used on other Klingon vessels, and, after getting over the initial shock of
seeing a human in a KDF uniform, most Klingon Engineers have worked with and adapted his
techniques to their own ships.
2 weeks before Kieran found out that he was being transferred back to the Federation, he
began to receive messages from his parents and friends again, who were quite relieved to
see him alive and well. After some initial
confusion, Kieran and his family figured out what had happened, and why his messages had
never reached their destination
late July of 2376, The Federation requested through their Ambassador, Worf, that Kieran be
returned to Starfleet and the Federation. The
Klingon Defense Force reluctantly agreed, and issued the necessary orders to Kieran. The SuDqul, being on the far side of the Klingon
Empire, about to embark on an exploratory mission, was ordered to return Kieran to
Federation space, and, early on August 1st, 2376, arrived at Kierans
transfer point, Star Base 138, near the Federation/Gorn border. It was discovered enroute to SB138 from
TyGokor that Aryn was finally pregnant with their first child, after trying for 2
years now. The SuDqul stayed at SB138 until
late August 2nd, and then, returned to Klingon space without Kieran. Kieran and Aryn said their good-byes, and Kieran
promised that he would somehow be there for when his child was born.
transported over to the Starbase after the departure of the SuDqul, and was immediately
sent to the Star Bases medical facility for a full medical and psychological
work-up. It was also at Star Base 138 that
Kieran was promoted to the rank of Lieutenant Commander and given his new assignment,
Chief Strategic Operations Officer on the USS Vincent.
Kieran was somewhat surprised by his new duties and rank, still expecting to be
returned to the rank of Ensign, and began to brush up on his new duties, and to review the
files he would need to know for when the Vincent arrived.
wore his Klingon Defense Force uniform for the first couple of days at SB138, and
didnt change into a Starfleet uniform until he was actually given his promotion and
new assignment. The other Starfleet officers
and civilians gave odd looks at Kieran and most gave him a wide berth. Kieran did have an incident with a security
lieutenant from the Star Base staff who wanted him to turn in his Klingon weapons. Kieran told the security officer that no
respectable Klingon warrior would be required to turn over their weapons, even on a
Federation station, so, why should he. The
incident came to blows, and the security officer found himself in the Star Bases
infirmary with 5 broken ribs, a fractured left fore arm, and a broken right knee cap,
while Kieran was treated for a cut lip. After
a brief investigation by the Star Bases Internal Affairs office, Kieran was allowed
to keep his weapons on him, and was also requested to keep his distance from the officer
in question. No formal charges were brought
up against either person. Kieran was also
told that he was back in the Federation now, and would have to modify his behavior
accordingly, this was not a Klingon station, and that he wouldnt get too many
chances like he got this time. Kieran took
this advice and pretty much isolated himself while waiting for the Vincent to arrive, only
coming out to eat and meet with the Star Base Administration to receive his new position
the Vincent arrived, Kieran transported over to his new ship, and settled in the best he
could, still missing his wife, and his old companions on the SuDqul.
served reluctantly on the Vincent, but he never complained about his transfer back to the
Federation, making sure that he would not bring any dishonor to his wife's house. While
onboard the Vincent though, he made contact with some old friends in SFI and at SF
Command, calling in some favors in an attempt to get transfered back to the KDF and Aryn
and their unborn child. After three months of efforts, he was able to get transfered back
to Earth to go through the Federation/Klingon Exchange Training Program. At the end
of the program, Commander Jamie Stieger, Kieran's friend from his Academy Days, who now
worked for the Diplomatic Corp, arranged a surprise for his old friend. Jamie set it up so
that Kieran's assignment in the KDF would be back on his father-in-law's ship, and that
the SuDqul would be able to pick him up at Earth, and also for his new family to be there
at the completion of the training program.
was quite surprised to see his wife (who was quite pregnant as well), his father-in-law,
Komar HoD, and the senior staff of the SuDqul, along with Jamie, Molly and Pavel, and
Kieran's extended Earth-based family as well. The ending of the program began a week-long
party in South Boston, with Kieran's parents meeting Aryn's father, and the whole
neighborhood opened up to welcome home and congratulate Kieran. Aryn and Komar were
welcomed into Kieran's family, but in quite a different way than Kieran was welcomed into
Aryn's. Friends and family he hadn't seen in years would drop by during the week, and his
parents would make space somewhere in the house. Even Komar stayed for two nights at
Kieran's parent's home, so as not to bring Kieran any dishonor in front of his family.
Even Kieran's brother and sister came home to meet their sister-in-law.
the party did end, and Kieran departed his family home yet again, this time in the uniform
of a Klingon Engineer with the KDF rank of Soghla', which was the equivilant to his Lt.
Commander rank in Starfleet. He was officially transfered to the KDF as part of the
brought the Engineering Department on the SuDqul back up to his exacting standards in no
a month on the SuDqul, Aryn gave birth to their first child, a son, born March 2377. He
was given two names:
Name: Goibhnie, son of Kieran, of the House of Komar
Human Name: Goibhnie Saemus O'Donnell
was going well for Kieran, until the SuDqul was assigned a new mission in the middle of a
patrol run of Klingon/C'hakilian border. The SuDqul was sent to gather intelligence inside
just 5 months old, was in Kieran and Aryn's quarters when the event happened, just barely
out of Klingon space. A C'hakilian warship came out of the SuDqul's blind spot and
attacked the ship before it was able to decloak. 1/3 of the crew were killed in the first
strike, and the ship took heavy damage. Kieran did what he could to keep the weapons
on-line, and the SuDqul got a few good shots off, but the C'hakilians had the advantage in
this battle. The SuDqul was severely damaged, but not destroyed. But, there was not much
left to salvage. By the end of the battle, there were only 4 pockets of air in the entire
ship, and only 12 members of the crew still alive, but only 3 were still on board the
remains of the SuDqul. Kieran was one of them. Komar HoD was dead, along with the rest of
the senior staff, except for Kieran and Aryn. Aryn had been in their quarters with
Goibhnie when the SuDqul was attacked. Aryn and Goibhnie though were not on the ship, they
had been taken along with 7 others of those who remained alive, supposedly taken by the
and the other two klingons were found a few days later, slightly dehydrated by the IKV
Kaval, a B'rel-class Bird of Prey. They were brought to a Klingon starbase and debriefed.
then, Kieran has been working with Klingon Intelligence to help find his missing wife and
child, and the other members of the SuDqul.
a few weeks ago, it was assumed that the C'hakilians had kidnapped nine of the 12
survivors, but, recent intelligence has determined that the C'hakilian warship left the
area at the approach of 2 additional Vor'cha-class cruisers. After scanning the heavily
damaged SuDqul, the lead Vor'cha fired torpedoes into the hulk that was the SuDqul,
rendering it unsalvageable, and transported the nine members of the crew that could be
After being rescued, Kieran
was assigned to Klingon Intelligence, and for the next year, was trained
in Klingon Intel techniques and how to use the standard Imperial
Intelligence work kit (i.e., agonizer, pain sticks, computer programs,
etc). He was assigned numerous field missions inside and outside of
eventually assigned to the IKS Hegh leng, a B'rel-class bird of prey,
commanded by K'rahl la' of the House of K'brd'Lok, and assigned to the
job of acting Gunnery Officer while he was there looking for members of
the House of Lovtal, who were suspected in being instrumental in his
family's demise. Kieran's first mission on the Hegh leng was a hastily
arranged diner at the K'brd'Lok estate prior to their mission: an
engagement with the Borg. On that mission, he was able to successfully
interface with the Borg ship and implant a virus that caused some havoc
for a brief period of time, allowing the away teams from the Hegh leng
to succeed in their mission.
to Avalon Fleet Yards right before the evacuation of said base due to
the C'hakilian War, the Hegh leng blows up. Sabotage is assumed. Kieran
meets 4th year cadet Patrick Flynn while trying to get a computer with
an encryption/decryption module on AFY during the evacuation. He then "aquired"
Flynn and brought him aboard the S'ten Hathos (a stolen Romulan B-o-P),
also under K'rahl HoD's command. Flynn wasn't happy, but he has since
grown in his role as a Science Officer/Intel Officer under Kieran's
tutalage. Instead of heading to kaleb IV with the rest of the fleet from
AFY, K'rahl and crew went to the klingon starbase Klach d'kel Brakt.
