Is there any quests or anything with the actual Knights that wear these? If not I would like to, with the permission of the creator of course, make a large quest mod dealing with the Dread Knights, I would call it "Invasion of the Dread Kingdom" they would probably be a new race that most likely would oppose all races other than there own. They seek only to exterminate the other races to have the "Kingdom" of Nirn to themselves. What would you guys think?

I haven't seen any quest with the actual Knights - likely there are some quests that treat it just as another armour - I have one I'm working on for Veloth's Child - Jojo gave a generous usage of the meshes as has Bahamut who converted them - I'm sure Jojo would approve of his work being used this way

Not sure about your quest though - how invincible are these guys - is it just a full on war mod you are after?

I wouldn't want them to be to Invincible, You do have to beat them afterall. I would however want them to be a major threat. It would more than likely happen that everyone takes up arms aganst them and a war ensues yes.
