Is there any official info about MK's involvement in Skyrim? I heard plots about plots the he's working or helping the team. Is this true?

Nope.


That'd be the wishful thinking of us crazy lore nerds. He has written several things about Skyrim already.

I'd really like to know this as well. It would make me much more excited about ES5 than I am already to hear that he had a hand in crafting the story.

I seem to remember a post he made on the Lore forum quite some time ago that essentially teased the setting for ES5 and even gave a bit of a tease about what the storyline will revolve around ... the cyclical nature of time, I believe is what he hinted at. I can't seem to find the post anymore, but the fact that at least part of what he hinted at in the post has turned out to be true (the story is set in Skyrim) gives me hope that he had more of a hand in the writing of Skyrim than he did for Oblivion.

I forgot.. why isn't he on the team anymore?
