The legendary sword Caliburn was something that was not unfamiliar to any qualified people of Brettonia.
Its last and only master was the illustrious Knight King of Brettonia, whose peerless military might once overawed the world. When he was still young, the Knight King pulled the sword Caliburn from the stone. Since then, he began his legendary life. He led his armies in successive victories, defeating all of the enemies of Brettonia, unifying the political power, and setting up the Knights of the Round Table that were admired by countless of people.
