All joking and mucking about aside, Lucifer kind of scares my pups and me (in a good way!). They both are afraid of him (Walter moreso than Schro), and he is just amazing. :3
My only thing is that he might need to get Niflheimers to do more things, or maybe be a twinge more rewarding or giving out punishment? (Is signing Schro and Walter's death warrants?)
