The Iblis was a yellow and bulky transgalactic cargo ship. Under Captain Et Cetera and swing-shift pilot Orloff Tree, it commonly plied a trade route from the Peach Nebula and was often falsely believed to be smuggling illegal bootleg concert recordings from there.

In 2001, while navigating the Erlenmeyer Asteroid Field on a routine mission, Iblis picked up strange readings on its scanners and the words "bad design" and "out-of-date color scheme" on its Long-Range Space Radio. Tree relayed this information to the Lirgonian flagship Gilded Excelsior, leading to the Battle of Erlenmeyer between it and the Wotwot ship, WSS Ferlinghetti, that had been detected.
