Witch-king Of Angmar

So you're a king of men, just ruling and being all kingly and stuff. And this dude shows up with a really nice, shiny ring for you. Of course you take it right? Well, if it turns out it's a ring of power, and the dude that gave it to you was the dark lord of Mordor (and he has his own ring that sorta controls yours), and now you're destined to be a ringwraith. but hey, at least you're the leader right? And then a brick artist named nameless_member builds a nifty MOC of your helm, so you have that going for you.
