Like most Victory-class Star Destroyers, the Guardian was originally built in the waning days of the Galactic Republic to help in the Clone Wars before it became part of the newly formed Empire. It would remain in service to the galactic government until it was sold in a deal with the Corporate Sector Authority as part of their purchase of 250 Victory Mark I's. It served with the CSA fleet for a number of years, and even went through an upgrade into a Victory Mark II, until Sulimurr was able to buy it through her contacts within the organization.
