The quill store had quills and ink and rolls of parchment. And even a magical self-writing quill.
staff members were amazing too. I'm pretty sure they actually live there. It's truly just a world of its own and impossible to find any evidence otherwise. This is the "worst" spot I could find in either place. It's the end of the road and just a wall, but look at what a wall! Staff come and go, but there's someone nearby in case you need any help. (Elsewhere you might call that security, but not here. Here, they answer questions and point you in the right direction.) I assume they may cast a spell on you if you try to snoop, so I acted casual. You can't see through the windows either, not that I tried. I totally tried. Really though, on my "find some mistake somewhere quest" this is the best I could come up with. A cute, funky wall with a door that fit right in.
