Title says all. I can't find where it would be. Gone up the stairs behind the wall and looked in the large room with many chests.
Suggestions?

It's on the left side of the room where Alduin's Wall and the long table is. There's an armory there with blades armor and weapons.

Thanks, Korr, don't know how I missed it. I walked down from upstairs, and there was the room on my right. Appreciate the quick reply.
