Sorry, but it's thread necromancy time!
This is simply too useful an idea to let go of. For those new to the TES fanfiction arena, a list of recommended stories for them to start with.
Anyway, here's a few of my suggestions:

Edit: I also highly recommend the story "The Tale of Matthias Etanne" by Hadrian. Sadly I cannot find a link at the minute, so if anyone knows where it's posted could they put it up?Short stories and novella lengthhttp://www.fanfiction.net/s/1874414/1/Guards

Edit: I also highly recommend the short story "My Heart" by Shades. Sadly I cannot find a link at the minute, so if anyone knows where it's posted could they put it up?This is just a selection of some of what I consider to be the finest stories written in the TES universe in the several years I've spent reading them. I hope others gain as much enjoyment and inspiration from these as I have
