The Aggressor was the starship of the Nova Blades pirate gang. The ship crashed on Rishi some years before 3637 BBY, leaving its crew stranded on the planet. Over time the pirates were able to return to the space and made Rishi their new base of operations in the western mountains of Horizon Island, converting the crashed hull of the Aggressor into a social and storage hub, which included living quarters, manufactories, security stations and more.
