I wish I had rolled a Char for mine, just so it would have the right 'vibe'. However, I was swayed by the mighty power of the Norn. I thought given the time that some Norn would have picked up some scientific and alchemical know-how...especially with their interaction with the Char.
Dunno why but for me a human female necromancer just seems so right. I haven't even made one yet but I know from the bwe's that they just seem to fit so good.
Pale fair skin, ghostly wraith eyes, dark hair in pigtails, and that face that has that I'm better than you and I know it look to it.
