Troax, an Imperial Army lieutenant, participated in the Skirmish on Dac. He was under the command of Commander Sturves while serving on the Sea Lion.
During the reign of Darth Krayt's Galactic Empire, Troax held the rank of lieutenant within the Imperial Army. He was stationed on the Sea Lion under the direction of Commander Sturves. Following the Emperor Darth Krayt's command for the extermination of all Mon Calamari inhabitants of Dac, Troax, along with the rest of the Sea Lion's crew, was assigned to hunt down the Mon Calamari who had escaped to the depths of the planet's oceans.
In an attempt to destroy a refugee settlement, the Sea Lion deployed Shark Squadron, a group of Shark subfighters. However, Mon Calamari Rangers commanded by Tanquar launched an attack on the squadron using their Krakana fighter craft. As the squadron began suffering losses, Commander Sturves instructed Troax to deploy a team of seatroopers into the water. Troax dispatched Alpha Squadron to address the threat, but upon exiting the Sea Lion, they were ambushed by Imperial Knight Treis Sinde, resulting in the entire squad's demise. Sinde then infiltrated the Sea Lion, inflicting significant damage to the docking bay and causing the ship to flood. Troax informed Commander Sturves about the ship's flooding, prompting Sturves to immediately order a retreat. Troax then ordered Shark Squadron to provide cover for their departure, and the Imperials retreated from the battlefield.
Troax made a small appearance in Legacy (2006) 32, which marked the beginning of the Star Wars: Legacy's Fight Another Day story arc.
