There is a person in Scotland called the Lord Lyon. His job is to make sure that people use the correct symbols and images for their family crests and coats of arms. These symbols and images are important because they tell the story of a family's history and identity. The Lord Lyon also decides who is allowed to use certain symbols and images, and he makes sure that nobody copies someone else's crest or coat of arms. Basically, the Lord Lyon helps people protect their family symbols and images so that they are used correctly and respectfully.
