Kagak was a male Klingon in the Klingon Defense Force in the late 24th century. He was born on the planet Pheben III, one of three siblings. He, his brother Fuhrman, and his sister B'Ellor were raised primarily by their grandmother, Tabona, on her farm.

Not having the aptitude for farming, Kagak left home to join the KDF. He was assigned to the IKS Kreltek, and later transfered, along with several others, to the IKS Gorkon. When the other former Kreltek crewmembers plotted a mutiny at Elabrej, Kagak passed the information on to Leader Wol.

In late 2376, Kagak invited his squadmates Wol and Goran to join his family on Pheben III for the celebration of yobta' yupma'. (KE novel: A Burning House)
