This Imperial Officer oversaw Dead Castle which was located on Dennaskar, circa 3 ABY.
This officer participated in the assault on this planet, where he aided Imperial forces in the complete wipe out of the local population. Following the annihilation of the planet's inhabitants, the officer took up a post at the planet's former center of power. On one occasion, Darth Vader journeyed to the planet for the express purpose of torture of Tay Vanis. Vanis's psyche was ultimately shattered, and he was reduced to a persistent vegetative state. Vader confined the broken man to a small, secured chamber within the castle, and the officer was among a select few aware of Vanis's confinement.
Circa 3 ABY, Luke Skywalker, Leia Organa, and C-3PO arrived on the planet in search of Tay Vanis. They eventually managed to connect with LE-914, Vanis's droid, who guided them to the castle. Skywalker successfully captured the officer, who then guided them to the small, locked room. Upon opening the room, a pre-recorded hologram of Vader materialized, addressing the Rebels and mocking them for discovering Vanis only after he had been rendered comatose through torture. While the Rebels were engaged in listening to the message, the officer seized Organa's blaster and attempted to use it against her. However, Organa swiftly retrieved Skywalker's weapon and fatally shot the officer through the forehead, resulting in his death.
