He’s equally excited, you see, about the little people - the NPC characters lower down the food chain who may not hold the future of an entire daedric realm in their hands, but are at least entertaining in their own little mentalist ways. There’s the chap you come across who’s afraid to sleep in his own house in case the walls fall in and crush him, for example, who asks you to find him a truly safe place to sleep.
There’s the mad woman in the wilderness who is obsessed by having one of everything in the world - from creatures to objects - and whose whims you can only satisfy if you’ve got a couple of aeons to spare. A more professional obsessive, meanwhile, runs and gives tours around the Museum of Oddities, to which you are asked to become a donor as the amount of bizarre and useless objects in your inventory starts to build up.
Speaking of which, more obsessive fans will be delighted to hear that Shivering Isles is due to be the first Elder Scrolls game to find a use for calipers - the heretofore useless household implements that have been found (and left) inside the barrels and chests of Tamriel for countless ages.
