The Battle aboard Knightstar was a key battle early on in the War of Twelve Heirs, as it not only aw the death of Corae, one of the triumvirs of the House of Mythos, but also saw the Proelicitia enter the war. Corae and a force of Mythosian marines boarded Knightstar and incapacitated the crew before heading the bridge. Once there, Corae and his Sith followers engaged the members of the Proelicitia in a duel. All Corae's Sith Lords were killed before Corae himself was decapitated by Lacertus.
