Born on Qo'noS to Mogh on December 9, 2340. Was the first Klingon to enter Star Fleet Academy at age 17 and graduated to becoming a security officer on the U.S.S. Enterprise. He has a son by K'Ehelyr called Alexander Roshenzko. In 2368 his spinal column was shattered, paralyzing him, but was eventually repaired by genotronic replication developed by Dr. Toby Russel. After the destruction of the U.S.S. Enterprise NCC-1701-D at Veridian III he took extended leave to live at a Klingon monastery on Boreth. He returned to the Federation to work at Deep Space 9 as a Strategical Operations Officer. When that became uncomfortable he left the position and moved in to quarters on the U.S.S. Defiant NX-74205. In 2373 he rescued Dr. Bashir and Martok from the Dominion in the gamma quadrant and in 2374 he married Jadzia Dax. Worfs hobbies are Klingon history, martial arts and opera. He was introduced, by Guinan, to his favourite drink, prune juice, "a Warriors drink".

Born into a common house, Martok was originally denied officer status by Kor. He gets a battlefield commission after helping drive a Romulan boarding party off. After being abducted and replaced by a shapeshifter, Martok escapes back to the alpha quadrant in 2372 and becomes the commander of the base Deep Space 9. At the end of the Dominion War, Chancellor Gowron comes to Deep Space 9 and assumes control of all the forces there, whereupon Worf kills him and passes the title of Chancellor on to Martok. As Chancellor, Martok leads the combined forces of the Klingons, Federation, Romulans and Cardassians against the Dominion to finally defeat it.

Son of Worf, he was born without the knowledge of his father to K'Ehelyr and raised by her as a child. Before her death at the hands of Duras, Worf learned of his existence but did not acknowledge it for some time because he did not wish for his bad reputation to fall on the head of his son. Alexander eventually moved to Earth when Worf eventually accepted him and was cared for by the Rozhenkos, Worf's adopted parents. He joined his father a year later aboard the Enterprise-D. In 2370, when deciding on whether to take the first Rite of Ascension he was visited by his future self. Let us see if the world of Blood Bowl can write some more of this childs history!

Born in 2345 to Mogh, he was left in the care of Lorgh, a family friend. Joining the Klingon Defence Force when he reached adulthood, he rose to become a commander. He discovered Duras's coverup of Khitomer and worked with Worf to uncover it. In the end he was severly injured by an attack of Duras's and Worf was forced to take a discommendation. After the death of Chancellor K'mpec he lent his support to Gowron, and led his forces to victory against the Duras in a critical battle. This earned the Mogh family new respect and Kurn recieved a seat on the council which was all taken away when Worf was seen as defecting to the Federation during a time of war. In 2372, Kurn went to Deep Space 9 in an attempt to convince Worf to return to Qo'noS with him, so as to restore the family reputation. When Worf declined, Kurn demanded to be killed in Mauk-to'Vor but when this fails he gets brainwashed and becomes Rodek of the House of Noggra.

Commander Kor is a ruthless military governor of Organia. At a hundred years old he reunites with Kang, Koloth and Dax to seek revenge on The Albino, a Klingon who killed all their first-born. He finally dies on the battle field, singing a dirge over his comrades bodies until he succumbs to his own wounds.

Kang is a known traditionalist who laments the passing of the old ways. His ship was destroyed by the Beta XII-A entity which fed on hatred, but not before being beamed with his crew onto the U.S.S. Enterprise. The entity continued to feed there until a truce was formed between Kang and Captain James T. Kirk with the help of Spock. In 237o he rejoined forces with Kor, Koloth and Dax to seek revenge on The Albino who killed all their first-born. After striking the fatal blow Kang succumbed to his massive injuries, dying on the battle field.

Captain Koloth of the I.K.S. Gr'oth became first known for his service as a Klingon diplimat in negotiating the Organian Peace Treaty with Captain James T. Kirk onboard Space Station K-7. He became an honoured aquaintance of the Trill and was dubbed D'akturak by Dax. In 2370 he rejoined forces with Kor, Kang and Dax to seek revenge on The Albino who killed all their first-born. Over a century old, he succumbed to his wounds on the battle field, dying with honour.

A daughter of the great Duras house, and sister of Duras himself, she shared in many of her brothers deeds. After Duras's death at the hands of Worf she and her sister, B'Etor, conspired with the Romulans in a bid to bring Toral to power as leader of the council. This plunged the Klingon Empire into a civil war, after which she dissapeared for two years. After hiding out, the two sisters returned to the political game, trading minerals for money to increase their military might to make attempts to seize control of the Klingon Empire. The end came when the Enterprise-D stumbled upon their attempts to design trilithium weapons with the help of Dr. Soran. Lursa died when the return fire of the Enterprise-D destroyed her class D-12 bird-of-prey.

The longest presiding Chancellor ever, K'mpec ruled with an iron hand and through the Khitomer Massacre, which was the death of him. Duras sought to cover up his fathers actions in betraying the Klingons to the Romulans which K'mpec assisted in fingering Mogh as the betrayer. This was done unsuspecting of Kurn and Worf returning to Qo'noS to bring the truth to light. K'mpec spared both of Mogh's sons from death while retaining peace in the Council. K'mpec was eventually murded by Duras in 2367, poisoned with Viridium Six, but before dying appointed Picard as his Arbiter of Succession.

Son of Ja'rod, Duras was named after the powerful house that he was born into. Held a seat on the Klingon council by 2366 and led the cover up of the treachery involved with the Khitomer Massacre to make all signs point to Mogh. He then attempted to kill Picard and Kurn to prevent the truth coming out, but failed, yet the truth remains covered up to prevent a Klingon civil war. By poisining Chancellor K'rnpec he rose up the ranks to become a contender for Chancellor himself, and tried to kill his competitor, Gowron, with a bomb. During this period he killed K'Ehelyr, Worfs mate, for getting too close to the truth of Khitomer and was killed for revenge by Worf.

Son of M'rel, he was made Chancellor of the Klingon Empire in 2368 after the death of K'mpec. Killed by Worf in a challenge after forcing Martok to fight hopeless battles against the Dominion in order to weaken Martok's political power and reputation. "Bad Gowron! No gagh for you!"
