From the website:
Warhammer Fest is a celebration of everything about the worlds of Warhammer and Warhammer 40,000; the miniatures, the backgrounds, the stories and the games. You will encounter fantastic miniatures displays, seminars by our design teams, in-depth demonstrations and inspiring Design Studio displays.
You will also be able to pick up the latest releases from Games Workshop, Forge World and Black Library, including many items available for the first time over the weekend, along with exclusive event only merchandise. With such a wide range of activities, you can plan your day around specific elements, or just enjoy whatever grabs your attention.
