Walker was a BFF-1 bulk freighter under the service of the Empire. She was to deliver Habassa slaves to the Nebulon-B2 frigate Mayhem.

However the Rebels had learned of the convoy and sent an A-wing and a Y-wing to disable the Walker and then a Delta-class DX-9 stormtrooper transport Ranger to board and liberate the slaves, while the Y-wing held the Mayhem long enough for the operation to be successful.

The freighter was destroyed afterward.
