Wish I had thought of that name when I was complaining about Sam finding the answer to the dragon glass question (which he specifically went to Old Town to answer) the very night he first gained access to the restricted section. And I didn't realize that that same book, on the facing page, may also supply the cure for greyscale. Lucky break for Samwell and the world.
I wonder what grand answers he'll get if he turns the page? A DNA test showing that Jon is the son of Lyanna and Rhaegar?
