 Psychological Profile: Report of Starfleet Counselor Telnorri, DS9 Service Area
 Update to Enterprise File Report by Counselor Deanna Troi

 As the only Klingon in Starfleet, Worf has already achieved an illustrious and honorable career aboard the U.S.S. Enterprise
 as well as played a key role in Empire politics, but he keenly feels the effects of an often tragic life caught uniquely between
 the two conflicting cultures - immediately evidenced by the traditional Klingon baldrics he wears over his Starfleet uniform.
 This inner-felt conflict stems in part from his perception of honor as taught but not always practiced by his native people, and
 is complicated by family relationships which echo his duality of culture in both his personal and public life. Worf has even
 been put on report.

 He was born into a powerful political house on Qo'noS and carries vivid memories of a typical Klingon childhood. On his first
 ritual hunt before the age of six with his father's friend L'Kor, he attacked a large beast and it mauled his arm, providing a
 lifelong scar.

 However, Worf's life was changed forever in 2346 when his family was wiped out by Romulans at the Khitomer Outpost along
 their border; he has no memory of his father. The young man was thought to be the only survivor, and was soon adopted by
 Chief Sergey Rozhenko, a human engineer nearing retirement aboard the U.S.S. Intrepid, which provided the first assistance
 at the scene.

 The next year Worf lived with him, his wife Helena, and their son Nikolai among 20,000 colonists on the farm world Gault and
 later Earth, where the bigger and stronger Worf had a hard time adjusting to less-violent human culture and the two boys
 often disagreed. Finally, at the age of 13 while playing in a championship game as captain of his school soccer team, he
 unintentionally broke the neck of an opponent and the boy died a day later - forever guilting him into a life of restraint among
 humans. On the other hand, the Khitomer incident instilled in him a life-long hatred of Romulans.

 To feed his thirst for his native people's culture, the Rozhenkos consciously exposed Worf to as much as they possibly
 could - serving him Klingon food, including his favorite rokeg blood pie, and sending him to Qo'noS for his initial Age of
 Ascension ceremony in 2355, at age 15. As usual, when on the homeworld he stayed with a cousins' family but felt rejected
 and ran away to the nearby mountains. There, while undergoing the Rite of MajQua in the lava caves of No'Mat, the vision of
 the original Klingon warrior Kahless came to him, prophesying that Worf would do what no other Klingon had done.

 Worf entered Starfleet Academy with Nikolai in 2357, but his impetuous brother left school and returned to Gault while Worf
 went on to graduate in 2361. The fear of depending on others to protect him had been the prime point of his own entrance
 exam's psych test.

 In 2364 he signed aboard Picard's U.S.S. Enterprise in command division as a junior-grade lieutenant, at the time wearing a
 century-old Klingon baldric. After the death of Security Chief Tasha Yar, he became acting chief and then assumed the post
 full-time in early 2365, switching to security full-time n the operations division and gaining a promotion to full lieutenant. His
 shipmates formally promoted him to lieutenant commander six years later with a ceremonial holographic ocean-dunking on
 an ancient Terran naval vessel.

 Aside from a few weeks of dating fellow officer Deanna Troi in 2370 on the U.S.S. Enterprise, his most serious romance to
 date involved the half-human Ambassador K'Ehleyr. Worf had ended their initial affair in 2359, during his Academy years, but
 K'Ehleyr refused to begin anew and take vows after they mated in 2365 during her mission regarding the T'Ong sleeper ship
 incident.

 Worf's family tree took on surprising twists during his U.S.S. Enterprise career, beginning with the trumped-up charge that
 Mogh had betrayed Khitomer to the Romulans. The resulting probe turned up not only a second survivor and eyewitness to
 the massacre, his old nursemaid, but a younger brother who'd been left behind on Qo'noS, Kurn. Even when the traitor was
 proven to be not Mogh but Jared, father of the powerful Duras, Worf later accepted discommendation from Klingon society
 rather than cause an uproar in Empire politics had the cover-up been revealed.

 Worf was shocked to discover in 2367 that his interludes with K'Ehleyr had fostered a son, Alexander, when she
 accompanied the dying Klingon Chancellor K'mpec while old foe Duras, a challenger for succession, was a suspect. With
 her mate and son present, K'Ehleyr died after being attacked by Duras when she drew too close to the truth about Khitomer,
 and Worf in anguish killed Duras on his own ship. His captain was more than understanding, as he had been when Worf
 refused to donate blood to save a Romulan, but he was put on formal report for his actions.

 During the Klingon Civil War of 2367-68 Worf felt compelled to resign his Starfleet commission to become involved, but it was
 reactivated after the war. During that time he persuaded Kurn to support Gowron against Duras' sisters and their Romulan
 backers, standing up to the sisters when abducted and tortured. His aid of the victor Gowron eventually restored his family's
 honor, and Kurn won a seat on the High Council.

 Mogh was later rumored to be alive in a secret Romulan prison on Carraya IV, but though Worf's covert 2369 mission found
 the rumor to indeed be false he did discover - and agree to keep secret - a colony of shamed Klingon survivors from
 Khitomer, led by his father's old friend, L'Kor, and their Romulans guards who'd resigned to live with them.

 Worf dipped back into Klingon politics in 2370 after he questioned his own faith in the teaching of Kahless following the
 Carraya IV incident. His visit to the caves of Boreth, the legendary site of the great warrior's predicted return, was shaken up
 when Kahless did appear to return. Although later found to be cloned from ancient relics of the original Klingon warrior by the
 Boreth clerics, the response of spiritually empty Klingons to his presence led Worf to insist that Gowron accept the cloned
 Kahless as a returned Emperor and moral leader - in effect creating a constitutional theo-monarchy.

 He was even reunited with his foster brother Nikolai in 2370, when the two clashed again over the human's saving of the
 doomed Borallan village against Picard's orders and the Prime Directive to save his pregnant mate, a native. The two parted
 more amicably after the incident, however.

 After his mother's death Alexander was initially sent to live with the Rozhenkos on Earth, but a year later Helena returned
 with him to plead that Worf take him back for support and guidance. The two shared a testy relationship at first, but thanks
 to sessions with the ship's counselor - whom he eventually selected as the boy's foster parent if need be - they fared better.
 When a shipboard accident left him paralyzed, Worf considered the ritual Hegh'bat suicide until both Riker and Troi talked
 him out of it, pointing to Alexander's need for a parent; an experimental genotronic spine later restored his health. Shocked
 in 2370 to find his son returned through a time loop from 40 years in the future, be began allowing Alexander to find his own
 way - even if it was not the way of a Klingon warrior.

 During his U.S.S. Enterprise tenure, he birthed Keiko O'Brien's baby in Ten-Forward during a shipwide crisis in 2368, his
 only prior experience having been a Starfleet emergency first aid class. He dislikes surprise parties and diplomatic duty.

 He also taught mok'bara classes to those interested aboard ship, won a bat'tleh tournament on Forkas III in 2370, and for a
 time tutored Doctor Crusher on the weapon; there is no word that he took her offer to join her acting workshop. He trains with
 a multi-level holo-program of personal combat "calisthenics," has also played Parrises Squares, and picked up the nickname
 "Iceman" from his U.S.S. Enterprise poker play. Other interests include Klingon novels, love poetry, and a love of Klingon
 opera. His favorite beverage, christened as a "warrior's drink" when introduced to it by Guinan, is prune juice.

 Following the destruction of the Enterprise and break-up of its staff in 2371, Worf sent Alexander once again to live with the
 Rozhenkos on Earth and went on extended leave to revisit the Klingon monastery and clerics of Boreth in search of a
 spiritual answer to the letdown the rapid events provoked. He found their discussions enlightening and considered resigning
 his Starfleet commission, but in early 2372 he accepted Captain Benjamin Sisko's request to join the Deep Space Nine staff
 in light of renewed Klingon friction after dissolution of the Khitomer Accords and their short-lived invasion of the Cardassian
 Empire. He had all but decided to resign and join a Nyberrite cruiser crew when the Deep Space Nine offer persuaded him to
 stay, having felt that his Starfleet uniform was a disgrace to his own people.

 Early on in the assignment Worf admitted to continued bouts of depression over the end of what he perceived as glory days
 on the Enterprise, and countered it somewhat by taking quarters on the station's starship, the U.S.S. Defiant, and finding a
 kinship with Dax, who trains with the bat'tleh and mek'leth as well.

 He soon got the chance to meet Klingon legend Kor, but that honor too was ripped away when image gave way to reality as
 the two fought over the Sword of Kahless relic they found on a quest.

 Worf's public opposition to Gowron's invasion left him largely unaffected until the Empire attempted to frame him for the
 so-called slaughter of 141 Klingon civilians amid a skirmish; the hoax was revealed only shortly before he would have been
 extradited for the crime and faced certain death. However, on Qo'noS his house was once again stripped of its honor and
 properties, including Kurn's seat on the High Council.

 His depressed brother showed up on the station asking for his own suicide rite. Only Dax's interruption stopped the ritual
 Worf was aiding, but after Kurn's unsuccessful death wish as a Bajoran deputy Worf realized his brother had no future and,
 short of suicide, opted to have his memory wiped and replaced with another Klingon identity, sending him to live with a family
 friend. Even then he lived with the regret that his actions had been forever tainted by his human-learned values of mercy.

 Disciplinary Notation: Captain Jean-Luc Picard, SD 44248

 It is with regret that I make this entry in the personal file of Lt. Worf, whom I consider a fine officer. However, despite
 whatever sympathy I have for his personal reasons and the ways of his culture I cannot condone murder by anyone wearing
 the Starfleet uniform. The officer in question is spared further disciplinary action only due to the circumstances of the
 location aboard the Klingon vessel Vorn and the not-unexpected indifference of the Klingon Empire to the incident.

 Psychological Profile:
 Update SD 50500, DS9 CMO J. Bashir, M.D. recording

 Sparked by his spurning by Grilka and his uncharacteristic aid to Quark on wooing her the Klingon way, Worf's immediate
 friendship with Lt. Cmdr. Dax has now blossomed into full-blown romance; luckily she is one of the few species on the
 station compatible with the physical demands of the situation. The arrangement with Dax as his Par'machkai has stopped
 short by mutual consent of the traditional mating step required and seems to be affecting Worf in a positive way, aside from
 the squabble on Risa when what I perceive as Worf's reactionary tendencies held sway during his brief alignment with some
 New Essentialist activists there.

 Worf has encountered few further difficulties regarding his divided heritage. He had no problem helping to expose secret
 Klingon mining of the space around outer Bajoran colonies and fighting his brethren of a century ago when time-traveled to
 Station K-7. He was part of the covert team trying to prove Gowron was actually a Changeling double earlier this year, and
 sparked a challenge to the death with the chancellor. Although the team helped expose General Martok as a Founder, Worf
 left with the two still at odds over his defiance of Gowron a year earlier that cost the House of Mogh its official honor.

 His biggest qualm has been a quest for privacy, and took quarters on the usually empty Defiant to relieve the edginess he
 had felt ever since arriving here. I am told he often can be found there listening to Klingon opera blaring over the com system,
 usually from his favorite singer Barak'karan -- not surprisingly, a traditionalist.

 He continues to utilize the Holo-programs for recreation, including his combat "calisthenics," commanding the historic Battle
 of Tong Vey, but has no stomach for zero-G exercises. His posting here has broadened his horizons in at least two ways:
 he has renewed his study of the Ferengi Rules of Acquisition, and has admitted a healthy respect for native Bajoran beliefs
 concerning the Prophets based on his own spiritualism.

 Personnel Update:
 Starfleet Personnel Review Board, SD 50900

 Worf commanded the Defiant in Admiral Hayes' fleet against the second Borg invasion ca. SD 50890, and briefly found
 himself back with his old colleagues on the new Sovereign-class Enterprise when Picard rescued his crew and fought off the
 Borg's would-be temporal sabotage.

 Worf's action in recovering a new Jem'Hadar vessel intact ca. SD 50050 has already been duly noted in the record and
 decorated.
