Air Sick

I hope the cookies are pewter! My mom always said that I would grow up big and strong if I eat enough pewter cookies!

Does anyone else find it strange that this very recently published book seems to have an amazing amount of information regarding the Unmade? I don't have OB in front of me to pull from at the moment, but the book is new enough to have quoted Jasnah's research and Shallan is amazed at the detail unveiled in the Mythica. Even Mr. T doesn't appear to be this well informed. How did Hessi come to become so knowledgeable on the subject? Or is there a very simple answer that I glossed over?

It's been years in the making but in lieu of OB, I finally had to climb aboard the crazy train.
