"The Ring of Castellac" is based on a 1960 "Johan et Pirlouit" ("Johan and Peewit" in English) comic story titled "L'Anneau des Castellac" ("The Ring of Castellac").
Castellac is referred to as a kingdom, but this is not the case. The ruler is referred to as the Duke of Castellac throughout the episode, so the area he controls would be called either a dukedom or a duchy, not a kingdom.
