Robby London crafted a wonderfully, backwards, crazy world with Trolla as was evident in "Dawn of Dragoon." However in season two of He-Man Larry DiTillio turned Trolla into more of a fantasy world that was much like Eternia, with beings of all shapes and sizes inhabiting it. The Krooms and their fortress were one such new introduction to Orko's homeworld in the He-Man season two episode "Trouble in Trolla." As you can see here the artists at Filmation painted a beautiful panning background of the fortress, but I think most of you will agree that this location does not really belong on Trolla and would be far better suited on Eternia!
