This is the only episode that doesn't feature Prince Adam nor his transformation into He-Man.
The character model of the Cavern Monster can be seen as part of the Keeper's menagerie in The Heart of a Giant (1983).
The animated sequence of He-Man and Teela looking up at the fireworks would be reused at the end of The Greatest Show on Eternia (1984).
Elements from this story were adapted into a mini-comic written by Michael Halperin and illustrated by Alfredo Alcala that came with several Masters of the Universe action figures titled 'Siege of Avalon'. In this version, Delora is Stratos' human wife instead of his sister and it is she who is kidnapped rather than Stratos. Further more, the Torgs are replaced by a race called Ilkorts and the monster Molkrom is replaced by the demon Haramesh.
