From publisher blurb: Glacier Keep was the home of the Master Imbrund: a magical ice fortress that could endure the hottest summers and the fiercest siege. One hundred years ago, it vanished as suddenly as the Masters themselves. Yesterday, it returned. The Iron Heroes Gencon 2007 Adventure Glacier Keep by Adam Windsor contains the adventure itself, six pre-generated PCs of 4th level, three new monsters, one new template, and notes for adapting Glacier Keep for use in your home campaign.
