Overlord. They are knights who have fallen from glory and lost their honor. They wear fully armored suits of metal and patrol the city of Heaven's Peak. However, these Knights have taken up arms with The Silent Order, so when you eleminate the Order into serving you as their God, the Knights will also stop attacking you, even assisting you sometimes.
They are known for their weapons and armor made of Durium that offers them all excellent protection as well as weaponry of exquisite quality.
