The Quethold system was located in the Unknown Regions and contained several stars and the terrestrial planet Quethold. The latter was the homeworld of the Quesoth species, members of which spoke the languages known as Quesoth Common Speak and Quesoth Soldier Speak.
At some point after Empire of the Hand Grand Admiral Thrawn's battle against the alien warlord Nuso Esva in the Poln system of the Outer Rim Territories in 0 ABY, the former's flagship, the Imperial I-class Star Destroyer Admonitor, traveled to Quethold. It blockaded the planet in order to prevent Esva, who had allied himself with Quethold's reigning Queen of the Red, from escaping. After defeating the warlord's forces in 8 ABY, Thrawn's warship left the system for the Chaos Triangle with the goal of dealing with what the Grand Admiral referred to as Esva's "legacy."
