Games Radar has put together a four-page preview of The Elder Scrolls IV: Shivering Isles, based on some firsthand time they were recently able to spend with the upcoming expansion pack.
If you feel - like very many on Bethesda's forums - that helping a Daedric Prince isn't exactly in keeping with your character's mindset, then fear not, as Bethesda thinks you're all too young to wear worry lines on your faces. What happens in this realm stays in this realm, with no repercussions once you nip back to the land of Oblivion. Perfect stress relief, one could say, for the do-gooder who fancies wrecking more comeuppance-free lifewreckery over in the Shivering Isles. Your stock will rise as you earn the affections of the Prince, and you'll find yourself getting annoyed with the would-be adventurers who pour through the now wide-open portal between the two planes of existence. You'll even be given your very own chamberlain - or tips guide - the aforementioned Haskill, who you can summon at will, regardless of your situation. He doesn't take to this new arrangement terribly well, of course, and will have a few barbed comments to make if he feels you're wasting his precious time.
