Captain Tel-Peh was an officer in the Klingon Defense Forces during the 2360s. In 2369, Tel-Peh commanded the Vor'cha-class attack cruiser IKS Toh'Kaht during its bio-survey mission into the Gamma Quadrant. After the cruiser's crew were influenced by the energy matrix from the Saltah'na energy spheres, the captain began executing officers whom he charged with attempting mutiny. His first officer Hon-Tihl thought he was insane. Later, there was a battle for control over the ship with the conflict spreading to several decks. During the fighting, the captain captured the armory.
