I either lost or sold the Chimarvamidium quest book given to me by the Edwinna the Ald Ruhn mage. That's the book that you're suppose to return, after you just stole it for her.

I went to all the merchants that I might have sold the book to, but no luck. Can I fix this little problem with the game editor?

I don't know, but you can try. here's the command:

player->additem "object"

Thanks for the suggestion. If all else fails I'll give it a go. But I found out that the book might be available in a number of places, so I think I just search around a bit.
