The Wornal sector, a region situated in the Mid Rim, was adjacent to the Sombure sector, and is classified as a sector.
During the time of the Clone Wars, the Wornal sector fell within the boundaries of Republic territory, even though Bomis Koori IV remained as one of the final bastions for the Separatist forces.
During the era of the Galactic Empire, the Wornal sector found itself under the governance of Moff Eyrgen. Following the significant loss suffered by the Galactic Empire during the Battle of Endor in 4 ABY, Eyrgen established his own independent dominion within the area.
However, merely a few months elapsed before he was overthrown by Moff Utoxx Prentioch from the neighboring Sombure sector, leading to the incorporation of the Wornal sector into Prentioch's Dominion.
The New Republic achieved the liberation of the Wornal sector in 6 ABY, coinciding with Prentioch's defeat.
Fortunately, the sector remained untouched and unaffected throughout the duration of the Yuuzhan Vong War.
