Grokla was a male Klingon in the Klingon Defense Force in the 24th century. In 2376, he was second officer of the IKS Sturka under Captain Gatrell, during its mission of exploration and conquest of the Kavrot sector.
When the Sturka discovered several apparently pre-industrial worlds in the system Kavrot javmaH jav (Kavrot 66), Grokla and first officer, K'Draq, theorized that the natives had some kind of organic technology instead. Gatrell ignored these warnings, which proved to be true, and forced the Sturka to retreat from the battle for conquest. Gatrell blamed Grokla for this failure and had him put to death.
