I am having a heck of a time getting the sword to power up without becoming a criminal. I have hired mercs in taverns, taken them out to the woods and slay them to no avail. The sword does not speak to me afterwards. I have tried killing my wife, nothing. I have tried killing every guard and quest giver in Whiterun -- didn't power up completely and then I was KOS on half of the map.
Any ideas or tips for those that have actually powered this sword to the max?
Thanks!
