This attack on Khomm was a unilateral bombing of the Deep Core world of Khomm in 12 ABY by the United Warlord Fleets' Colonel Ivan Cronus, who commandeered the 13X and his fleet of Victory-class Star Destroyers under the orders of Admiral Natasi Daala.
This came as it was discovered that Dorsk 81 and Kyp Durron had visited the planet. Dorsk 80, Dorsk 81's predecessor, wished him to return to his old job, but 81 was simply trying to warn Khomm of the impending attack. Refusing to listen, the Khommites did nothing. Cronus carried out Daala's order with Crimson Command, devastating the planet and its population.
