I hesitate to point out anything related to *l*gnm*nt, especially *lw*ys *v*l, but perhaps I can summarize by saying that D&D tradition is opposed to the idea of a lot of kind-hearted vampires running around.
But The Giant has also given what appears to me to be a strong clue as to how vampirism affects character in OOTS: "Bringing me back to life is just a complicated way of annihilating the person I am today."
