Coronet Ion Works, situated in Coronet City, the planetary capital of Corellia, functioned as a business during the Galactic War. This conflict pitted the Galactic Republic against the re-established Sith Empire. In 3640 BBY, during the Battle of Corellia, the Empire seized the company's main offices, transforming them into a significant communications hub. Ultimately, Republic Military forces systematically eliminated the occupying Imperial troops in a meticulously planned assault, orchestrated by Colonel Rian Darok from the Republic Special Forces Division.
The initial reference to Coronet Ion Works appears within the Codex entry "The Rogue Lord's Accomplice," which focuses on Darok, found in the Star Wars: The Old Republic: Rise of the Hutt Cartel game.
