Return of Reckoning

On destro I have completed making 500 pies. I received the unlock which says "To get the Chef's Rolling Pin you visit a librarian in the Capitol." I went to the Lyceum and searched all of the librarians/merchants (twice) and no Chef's Rolling Pin. Where do I find the Chef's Rolling Pin trophy?

You'll find the vendor here:
