I don't think the codpiece quest has it's end yet. I went to the vampires and tried all sorts of ways to fight them, but it keeps ending off as something about me going back to them with the codpiece (which when I do is the same as if I met them for the first time).
And by enchanted armor, I guess it's just a fetish gear for mental satisfaction. You're a androgynous male going on adventures with a cursed armor and that penetrates your anal cavities. (Providing we are talking bout the same cursed gear)
