A specific kind of pipe, known as a steam pipe, existed on the planet of Exocron. Horzao Darr, the Captain in charge of the Maxion sky-dreadnaught, possessed a steam pipe, which he stored within his uniform tunic. While listening to the intelligence shared by New Republic pilots from the FarStar CR90 corvette who had landed on his ship to find a lost probe droid, he smoked this pipe.
