Blademaster is a title that can be awarded to a skilled swordsman. Many blademasters have Heron-mark Blades, and it is considered a bad idea to wear such a blade if one is not a blademaster.
To become a blademaster, one can either defeat a blademaster in single combat, or be judged worthy by a panel of five blademasters.
Blademasters have a terminology for different sword forms, which is widely used.
