The Knight of Blades is an unseen character mentioned on the Tales of Albion website.
History
The Tales of Albion states that he appeared with Jack of Blades and the Queen of Blades (together known as 'The Court') from the Void. He and the others are said to have demanded that the inhabitants of Albion bow down before them.
