I seem to recall reading somewhere (I think that it was written somewhere in the artists' proofs on Gamespot) that Melissan is *not* a Bhaalspawn, but the protector/guardian of the Bhaalspawn. I also seem to remember reading elsewhere that the 5th Bhaalspawn may very well be a dragon. I don't have any proof, but I think that I picked this up from the Black Isle boards when one of the developers was commenting on the Bhaalspawn characters. ???

Now where did I leave that doughnut?!
