ES4: Shivering Isles - Preview @ CVG

The latest preview of Shivering Isles is from CVG and covers well known territory:

The Shivering Isles are not a geographical location in Tamriel, they're the plane of Sheogorath, the god - no less - of madness. He does feature in Oblivion - his one quest for you is to make the apocalyptic prophecies of some backward villagers come true, in order to convince them of the end times and destroy their sanity. You and he team up to bring them a plague of rats, kill all their livestock, and then Sheogorath makes it rain burning dogs. Madness is what he does, all day long, and now you're in his jungle.
