Ashmead's Lock—Ashmead's Lock when it was a starship—was a former prison ship originally constructed by the Predori, an enemy of the Galactic Republic. As such, it originally housed Republic prisoners. Originally hidden within a gravity well, it crashed centuries before the Galactic Civil War on the forest planet Kashyyyk when the nearby well collapsed on itself. Many years later, it modified and rebuilt by Golas Aram and used as a prison by the Galactic Empire, while its Intellectual Processing Unit, SOL-GDA, remained intact.
