This story takes place on the planet Roon.
Action figures of Mungo Baobab, Admiral Screed, Governor Koong and Gaff were planned for inclusion in a second series of Star Wars Droids line by Kenner, but were never released. Only a couple of samples are known to exist, and are greatly sought-after by collectors.
The slave driver aboard Koong's galley was also one of Kybo Ren's pirates in the Mon Julpa arc, and got his hat and vest borrowed by C-3PO in The Pirates of Tarnoonga (1985).
One of the rowers sitting behind Mungo and Aurem in Koong's galley was in charge of the Droid auction on Tyne's Horky in The Lost Prince (1985). This would imply he went from selling droids into slavery to being sold into hard labor himself.
The old spacesuits that Threepio bumps into aboard the haunted spaceship wreck, is the same kind of suit worn by Jess Meade in The New King (1985).
