Some elves protest this, but they are successfully quieted. IV dies in captivity, just as the new Government gets underway. His funeral is not a large one. The elves learn the ways of mass production on the assembly line. All throughout the kingdom, children claim that they all heard him say he'd be back again some day.
VI is born.
The Claus family celebrates, but the elves aren't the least bit excited. V dies, under mysterious circumstances. He is found buried in the snow in the castle garden, frozen solid. Many think it is the work of Frosty, but no one can prove it. VI takes over, and immediately tightens up security.
