A lieutenant, an officer working on the bridge of the cruiser Third Horizon, was in the service of the Republic Defense Coalition throughout the High Republic Era. When the Great Hyperspace Disaster occurred, Jedi Master Avar Kriss inquired with the lieutenant regarding a fragment of hyperspace wreckage located far within the Hetzal system, a fragment to which the Force had guided her attention. He told her it was on a trajectory to collide with and vaporize against the largest of the system's three suns. The lieutenant initially believed this debris posed no threat, however, after Kriss requested further details, he realized it was a tank filled with liquid Tibanna and promptly informed Kriss and Admiral Pevel Kronara.
