Until a few days ago I have ignored the blades but on a whim decided I would go and have a chat with Paarthurnax. He told me some interesting stuff Dragons are born evil with a desire to dominate and that as a Dova I have something of that same nature. It brings up some interesting roleplaying options . It means I can indulge in a few evil acts assassinations and the like while still being generally decent and put it down to the inner war with my nature as a dova.
