Nice little tool. Was messing around a bit with it (after I made a backup of the savefiles )
Now I have a Seraphim on the Dark Side
Sort of, she can't take on the Main Quest. You enter Sloeford, Seraphim says "I should talk to the Towns Elder" (or something like that, I'm playing in german, so...). After that, there is neither the Light nor the Shadow Main Quest available
Dosn't matter at all, she has fun slaying monsters.
