Sometime in the period spanning from 22 BBY to 19 BBY, amidst the Clone Wars conflict that pitted the Galactic Republic against the Separatist Alliance, a battle transpired upon the planet known as Neimoidia. The Republic's swift assault on the planet caused widespread destruction to the grub hatcheries of the native Neimoidian species, thereby endangering their ongoing activities on the world.
The Neimoidia battle initially entered Star Wars canon in the fifty-second issue of De Agostini's Star Wars: Build the Millennium Falcon magazine, released around December 30, 2015. Within the Star Wars Legends continuity, a veiled reference to the battle of Neimoidia initially surfaced in Labyrinth of Evil, a 2005 novel penned by James Luceno.
