Admiral Pertaal Logris served the Imperial Navy during the Galactic Civil War. By 8 ABY, Logris was serving in the forces of Moff Kentor Sarne, an Imperial warlord who ruled the Kathol sector in the Outer Rim Territories. Under Sarne, Logris was in command of the Charis Fleet—the largest military fleet formation assigned to the sector—and was one of Sarne's staunchest supporters.
