King Muskar XII is noticeably absent from the post-war stories set in Syldavia: he does not appear at the launching of the moon rocket in "Destination Moon" and Tintin does not call on him for help when his friend Professor Calculus is kidnapped by Bordurian and later Syldavian agents in "The Calculus Affair". The post-war Syldavia may no longer be a monarchy; the latter "Adventures" set after World War II came at a time when various Balkan models for the fictional Syldavia had now been overthrown and their rulers exiled.
