HuDyuQ was a mountainous planet within the Klingon Empire, the location of a weapons development facility of the Klingon Defense Force.
History and specifics[]
In early 2376 (First Splinter timeline), Tiral, the former military governor of taD, and Commander Drex, first officer of the IKS Gorkon, were reassigned to HuDyuQ. Drex saw the assignment as a major affront and eventually contacted his father, Chancellor Martok, son of Urthog. Martok stated that he would not contest Captain Klag's decision to leave Drex behind on a ground assignment, leading Drex to criticize Martok's leadership of the House of Martok.
