I've been re-reading Storm Front recently, and I noticed an interesting passage (Harry speaking of his soul):
I did't know what they saw when I looked in there-it wasn't a place I poked around much myself (Page 35)
Does that mean that a wizard can see into their own soul? If so how would a spell that does so work in DFRPG.
I would rule that it does work, using a thaumatgury (making the impossible possible), using a complexity 12 divination spell (Due to the multiple facts you can gain ex. how others wizards judge your soul, based on how dark it is).
