Adrian Shephard is, as has been noted before, not terribly well-versed in fantastic lore. His knowledge of Greek mythology mostly involves 'Zeus can't keep it in his pants and if you piss off a god you're gonna get turned into furniture'. His knowledge of Norse mythology mostly involves 'These guys have gods who can actually
die, so the stakes are a lot higher, and their war god's an amputee'- and he only knows that last part because he had to sit down and look up
what the hell his T-minus user handle meant. His knowledge of the Fair Folk of Elysium? "Iron is bad, being rude is worse, eating their food is a good way to come home three hundred years after everyone you know is dead, and if you get into a deal with them you had better pay your part in full or
it will go very very badly."
This is all right, as far as it goes. It does not, however, cover everything a man in his position ought to know. When you've had a piece of their master smith's work grafted onto the end of your arm for the rest of your life, you need to pay attention to
every single thing he says until you leave his presence, even if you've paid the price he asked.
Especially if you've paid the price he asked. He might be more grateful than you think, and might have added a few things to the package that you didn't really understand.
Long story short: Shephard's just come in from the Greenbrier with a stack of paper in his (right, silver) hand and kind of a wild-eyed look. Apparently there are some exceptions to that whole 'the prosthetic hand only ever moves when and how I will it to move' thing he thought he had going on.
He's gonna need a beer. Or three.
