Kahlest
Kahlest was a Klingon and nursemaid to the infant Worf in the 24th century.
At the time of the Romulan attack on Khitomer in 2346, Kahlest was on the planet along with Worf and his father, Mogh. Kahlest survived the attack and was transported by the USS Intrepid to Starbase 24 for treatment. Due to the severity of her injuries, she was unaware that Worf had survived and that he may have been aboard the starship.
Later, that year, with the assistance of the Klingon Commissar, she embarked aboard a ship bound for her homeworld of Qo'noS at the Delta Awaro Trade Center.
In 2366, when Worf's brother Kurn came aboard the USS Enterprise-D to inform him that their father would soon be branded a traitor, Worf returned to Qo'noS and re-encountered Kahlest who verified Kurn's story.
At one point in her life Kahlest was the object of affection of K'mpec but she refused his advances because she found him "too fat". (TNG: "Sins of the Father")
