The Klingon first officer of the Toh'Kaht, who beams aboard Deep Space 9 mortally wounded in 2369 moments after his ship explodes on returning from a mission in the Gamma Quadrant.
Hon'Tihl is a Klingon officer who appears in the first-season Deep Space Nine episode Dramatis Personae. His vessel, the Toh'Kaht, comes back through the wormhole early from a survey mission and blows up almost at once. Hon'Tihl transports to Ops, gasps out a single word about victory, and dies.
The crew recover the ship's logs and learn that its officers had turned on one another. Hon'Tihl's own entries record his growing conviction that the captain was plotting against him, and the mutiny that followed.
The cause is a telepathic archive left by an extinct people, which replays their ancient power struggle through anyone it touches, and it soon grips the station's senior staff too.
