ive just figured it out. this may have been discussed on this board before, but tell me if im on the right track.
okay. vampires are supposed to naturally evolve to a state where they look like janos......winged blue beings, with clawhands and glowing eyes. also, vampires are intricantly linked to the pillars, which are he life blood of nosgoth.
okay, the last powerful vampires, kains lietenants, evolved but not into winged beings. because of the pillars being broken and nosgoth decaying they just devovled into decrepit unnatural states. kain knew this would happen. however, raziel for some reason was evolving naturally w/o the pillars. we all know the next part of this story.
but kain, being much older than raziel doesnt evolve wings. we know for a fact that he knew that vamps evovle into janos-like winged creatures. and it apparently angered him at least a bit when raz began to show signs of evolution before him. okay, now besides the obvious question as to why did raz change in the first place, why didnt kain?
i believe its because kain, when he was human, was a guardian of the pillars, and the pillars intricate connection with vampires put his evolution on a different path. perhaps, kain is evolving even slower to something else. something grander. its been hypothosized that kain will eventually become something like the trapped beast that was being drained in B02. could it be that kain is to become something as of yet unseen?
