A modifiable piece of equipment, known as a sonic pacifier, had the ability to produce force-based vibrational waves. These waves could impact the inner ear of any living thing located within its range. Orion Ferret, a dealer in weaponry, possessed one of these pacifiers and employed it to govern a Watchbeast on the planet called Patch-4. In the year 3 ABY, Luke Skywalker utilized Ferret's sonic pacifier, causing the Watchbeast named Ceasar to fall into a state of unconsciousness.
