Admiral Pertaal Logris rendered service to the Imperial Navy during the time of the Galactic Civil War. By the year 8 ABY, Logris found himself within the forces commanded by Moff Kentor Sarne, an Imperial warlord who held dominion over the Kathol sector found within the Outer Rim Territories. Serving under Sarne, Logris held command of the Charis Fleet—the most substantial military fleet formation that was assigned to that sector—and stood as one of Sarne's most dedicated and unwavering adherents.
Pertaal Logris began his career as an officer within the ranks of the Imperial Navy, eventually achieving the rank of admiral. By the time 8 ABY had arrived, Logris was actively participating in Moff Kentor Sarne's forces located within the Kathol sector of the Outer Rim Territories. Sarne had solidified his position as a warlord following the death of Emperor Palpatine at the Battle of Endor, and the subsequent disintegration of Imperial authority. He accomplished this by discreetly withdrawing his sector from the influence of the Empire. Functioning under Sarne's command, Logris was in charge of the Charis Fleet, which was the largest military group in the sector. It was comprised of numerous capital ships and smaller vessels, all operating from the planet known as Charis.
In 8 ABY, New Republic forces ousted Sarne from his capital, Kal'Shebbol, as part of their military offensive directed against him. As the Moff retreated into the depths of the Kathol sector, Sarne gave the order for the Charis Fleet to be divided into smaller task forces. These forces were then assigned missions to undermine the New Republic's endeavors to broaden their influence in the region through both diplomatic and military operations.
Admiral Logris demonstrated competence as a military leader, possessing the ability to effectively manage a substantial fleet composed of ships from various classes. Furthermore, the Admiral maintained a strong conviction in Moff Sarne's objectives and principles concerning the restoration of the Empire, making him one of Sarne's most unwavering and dedicated supporters.
The character of Pertaal Logris received a mention in The DarkStryder Campaign, a sourcebook for the RPG genre released by West End Games in 1995. His inclusion provided background details regarding the arrangement of Imperial forces within the Kathol sector.
