The home defense fleet of the Trade Federation's Neimoidian Defense Legions was massive in size. This fleet, stationed in the Quellor sector, had the duty of protecting the Neimoidian Purse Worlds, utilizing Lucrehulk-class Battleships as well as droid control ships that had been converted from cargo [transports](/article/transport]. The Federation formally allied with the Separatist Alliance at the onset of the Clone Wars, which spanned from 22 BBY to 19 BBY, bringing the Quellor sector fleet into the Separatist fold. Despite Separatist planets generally handling their own defense, entities such as the Trade Federation provided support in return for resources.
The Galactic Republic's 2nd Fleet implemented a blockade of the Purse Worlds during the conflict. In response to the hardship caused by the blockade, the Separatists sent the sector's fleet to engage the Republic forces. The battleships in this fleet were successful in holding off the 2nd Fleet.
The Quellor sector fleet received a mention in Rise of the Separatists, a 2019 addition to the Star Wars Roleplaying line from Fantasy Flight Games.
