Du'Qot was a planet along the border of the Klingon Empire and the Lyran Star Empire that apparently served as a forward supply base for the Klingon Defense Force, as a convoy schedule was apparently wagered in the Jadefire Run. (Star Trek: The Stoneship Files: "Dilithium Dance")
A raid led by the IKS Pterodactyl-of-Prey was launched by the Lyran Starfleet under the command of Brianna Reiss in order to turn the entire population of the planet into zombies. (Star Trek: The Stoneship Files: "Rode the 300")
