Librarian

There are many dangerous spirits in Sornieth. You only caught a glimpse of this one in between the rows of books. What could it want? It appears to be shelving the returns...
The Librarian roams the shelves at night, returning books to their proper locations.
Old hands at the Wandering Troop know not to bother The Librarian. The Librarian never talks. The Librarian never acknowledges anyone. The Librarian doesn't... move. Not in the ways you expect a person to move. Each step forward along the shelves just kind of...happens. You won't be able to tell how, even when you watch The Librarian. Even if you watched The Librarian for days.
Its... best not to watch The Librarian. You'll want to, of course. The only people that stick around at Wandering Troop are all the kind of people who'd want to figure it out, its only natural to be curious. No, its best not to watch The Librarian because sometimes, sometimes you'll see.
The Librarian is something odd. Something more like stone and smoke than like a dragon. It walks like a dragon, it's in the shape of a dragon. You'll hear the squeak of wheels from its shelving cart and think its a dragon. But if you look at it too long, you'll see its blank, alabaster face and its flickering thousand hands. It doesn't have the face of a dragon. It doesn't have the hands of a dragon. And definitely whatevers coiling within it, is not a dragon. Not at all.
No, better not disturb The Librarian. Its busy shelving the books, after all.
