Pressure pirates

Pirates operating under extreme pressure, known as pressure pirates, plundered vessels on the planet Yorn Skot. Employing heavy-duty machinery, they'd sink ships to extreme depths on Yorn Skot, causing them to implode, before salvaging the remains. A group of these pressure pirates, in collaboration with Waverton and Podlong Foahl, made an attempt to seize the Aurorient Express during the year 38 BBY.
