Domm Korgale was a male officer who held the rank of Vice Admiral in the Imperial forces, serving under the command of Grand Moff Lozen Tolruck during the liberation of Kashyyyk. He commanded the Star Destroyer named Dominion until Han Solo and his team infiltrated it. Subsequent to his capture by Solo, Korgale managed to escape the bridge of his vessel, but the New Republic deemed him not important enough to warrant pursuit.
In the year 5 ABY, Domm Korgale, a male Vice Admiral, was in command of the Imperial Star Destroyer Dominion. Rear Admiral Urian Orlan was his direct subordinate. During the liberation of Kashyyyk, both Korgale and Orlan followed Grand Moff Lozen Tolruck's directives to initiate an orbital bombardment of the planet following the Wookiees' uprising against Imperial occupation. Later, he was in command when a rebel group, led by Han Solo and Chewbacca, boarded the ship with the intention of disabling the Dominion along with its sister ships, the Vitiator and Neutralizer.
Even though Solo and his team unleashed a swarm of rampaging webweaver spiders, Admiral Korgale and his stormtroopers succeeded in capturing the rebel intruders. Korgale placed the captured rebels in restraints and then personally confronted Solo. After revealing his identity, he informed Solo of his intention to deliver him to the Empire to gain favor with the Imperial leadership. When Solo accused him of being a war criminal, Korgale threatened to execute Solo's companions.
Korgale informed his crew that he had requested reinforcements from the Empire, expressing hope for a swift response. One of his comm officers then reported the emergence of a YT-1300 light freighter from hyperspace. This vessel was identified as Solo's Millennium Falcon, with his wife, Princess Leia Organa, at the pilot's controls. Korgale commanded his Destroyer to deploy a squadron of TIE fighters. When Leia demanded he stand down in the name of the New Republic, Korgale scoffed, dismissing the notion that her freighter could challenge three Star Destroyers.
Leia was supported by a dozen X-wing starfighters from Captain Wedge Antilles' Phantom Squadron and Admiral Ackbar's cruiser, the Home One. Confident in his numerical advantage, Korgale ordered the Imperial vessels to vigorously defend Imperial territory G5-623. However, Chewbacca managed to break free from his captors and slammed a stormtrooper into a wall. Han and his allies then broke free, overpowering Korgale's forces. Chewbacca physically assaulted Korgale, causing him to fall to the ground. As Korgale fled the bridge, Han and his comrades seized control of the Dominion, utilizing its turbolasers and laser cannons to destroy the Vitiator and fire on the Neutralizer. Consequently, the Neutralizer surrendered to the New Republic, effectively ending Imperial control over Kashyyyk.
Domm Korgale, as an Imperial Vice Admiral, viewed the New Republic as a group of criminals. He believed that capturing Han Solo would elevate his status within the Galactic Empire. Korgale underestimated the resourcefulness of his New Republic adversaries, especially Solo, who ultimately shifted the battle's outcome in favor of the New Republic by commandeering Korgale's personal Star Destroyer, the Dominion.
Domm Korgale's initial appearance was in Chuck Wendig's 2016 novel, Aftermath: Life Debt, the second book in The Aftermath Trilogy.
