Weemell sector

During the Clone Wars, Loedorvia was situated within the borders of the Galactic Republic. Around 20.2 BBY, the astronomical object was the site of a battle between the Republic and the Confederacy of Independent Systems. During that confrontation, Confederate General Grievous ordered the release of the airborne hive virus disease known as the Brainrot Plague on Loedorvia.

The release of the disease, also known as the Loedorvian Brain Plague, killed tens of thousands of individuals in a single stroke. Before an antidote could be discovered, the resulting outbreak of the disease exterminated all of the Republic's clone trooper forces—as well as nearly every Human—in the Weemell sector. The sector was also rendered temporarily uninhabitable as a result.

The Weemell sector was first mentioned in Curtis Saxton's 2005 reference book Star Wars: Revenge of the Sith Incredible Cross-Sections.
