portrayed by Dorn) appears as the legal advocate of Captain James T. Kirk and Dr. Leonard McCoy after they are accused of killing Chancellor Gorkon of the Klingon High Council. He was also a member of the Klingon delegation at Camp Khitomer. Although not explicitly stated, he was intended to be Worf's grandfather and namesake. Worf has a son named Alexander with a half-human half-Klingon woman named K'Ehleyr, a character introduced in "The Emissary"; however, she is later killed in "Reunion", a "sequel" to that episode and part of the Worf story arc, leaving Worf as a single parent. Alexander has to live aboard Enterprise-D when K'Ehleyr is killed. After TNG ends, Worf gets moved to the Deep Space Nine space station where he eventually marries the Trill symbiont Jadzia Dax. (See "You Are Cordially Invited".) On DS9, Worf misses the Enterprise-D "family" that he had, often bemoaning the cut-rate work ethic and unfriendliness on the wayward outpost. The episode "Sins of the Father" introduces Worf's long-lost brother Kurn, who is also an orphan of the House of Mogh. Worf's adoptive parents have a biological son, Nikolai Rozhenko, whom Worf grew up with. Nikolai and Worf talk in "Homeward", where it is revealed that Worf will likely have a nephew or niece. In "The Bonding" (TNG S3E5, aired 1989), Worf adopts an orphan boy into the House of Mogh. In the first Star Trek episode written by screenwriter Ron Moore, the orphan Jeremy (played by Gabriel Damon) has a special Klingon ceremony to be adopted into Worf's family.Join me in the R'uustai, the Bonding. You will become part of my family now and for all time. We will be brothers. – Worf to Jeremy, "The Bonding" Storylines Backstory Worf was born in 2340 on Qo'noS (the Klingon homeworld) as the son of Mogh. Five years later, his parents moved to the Khitomer colony. Worf's parents were killed during a surprise attack by the Romulans on the Khitomer outpost. The colony's distress call was answered by the Federation starship USS Intrepid. Chief Petty Officer Sergey Rozhenko found Worf in the rubble and took him in after failing to find any living relatives. Rozhenko and his wife Helena raised him on a small farm colony on the planet Gault, a world of about 20,000 inhabitants, almost all of them human. Worf also has a human brother, Nikolai, with whom he often quarreled.
