The Trade Federation constructed a droid factory on the planet Eos. This complex featured essential components such as a landing pad, a command center, a power center, a building for manufacturing, and the main factory itself. For defense, it was equipped with a Planetary Gun. The facility's discovery occurred in 32 BBY thanks to the actions of Vana Sage, a mercenary, following a breach of contract; subsequently, Sage participated in a counter strike directed at the droid factory, which resulted in its complete destruction.
The video game Star Wars: Starfighter, released in 2001, includes the droid factory located on Eos as a setting.
