Galalloy Industries was a droid development and manufacturing corporation with a service history dating back to the days of the Galactic Republic. Galalloy was responsible for manufacturing the first true probe droids to search planets and asteroids for valuable resources, such as metals to fuel the processing plants of industry. Probots later helped to expand the Republic's frontiers into the deep, unknown reaches of the galaxy.
