They are humanoid in shape, seemingly slightly taller than most humanoids, wear crystal armor and wield crystalline swords, which they seem to wield with great skill. According to Sheogorath and Haskill, the Knights, much like their Prince, do not have a single original thought in their heads, making them perfect soldiers of Order. They are trained to be masters in swordsmanship, archery and magic making them some of the most powerful Daedra. Some tales say they were once mortals who worshiped Jyggalag and turned their flesh hard and rough as crystal and turned themselves into mindless minions of the ruler of logic and order.
