The King's Royal Guard is the guard that is stationed at Castle Araluen. They have to defend the royal family with their lives.
There are only few people who are chosen to join the Royal Guard. It is a position mainly for noblemen or the sons of noblemen. One exception is Horace Altman; after he travelled through Gallica and Skandia as the Oakleaf Knight, King Duncan decided to make him a knight in full and Horace was offered a position at Castle Araluen as Captain of the B-company of the Royal Guard. He went on to become the personal guard of Princess Cassandra.
