As the story progresses, Duralumin stages a coup d'état to conquer Silverland, following the orders of Mr. X, a large man clad entirely in boxy red armor and the ruler of the X-Union, a neighboring, proto-fascist federation of nations that wants to conquer the three kingdoms (Silverland, Goldland, and Charcoal-land). The King and Queen are captured, but help Sapphire to flee. Duralumin is about to proclaim his son king and himself as regent when he is assassinated by Nylon, who has been driven near-insane by the Duke's constant abuse. The mentally deranged Nylon proclaims himself and welcomes Mr. X and his armies in Silverland. Mr. X, though, soon makes it clear that he has no intention of letting Nylon rule, even as a puppet monarch, and merely keeps him around as a churlish buffoon.
