The Efficient, originally a Subla Ransom Medium Cargo Hauler, underwent modifications to accommodate a completely droid crew after being taken over and rechristened by the assassin droid known as SCr-114. To create space for a comprehensive ship droid maintenance, repair, and enhancement center, it was purged of elements like escape pods, living spaces, a life support system, recreational consoles, and food preparation units.
