For what it's worth, regarding the 'How are some of them still alive' question, me and some friends were discussing some of the details you can find in the queue, and there are implications that are... rather disturbing:
Victoria is shown to be constantly torturing and seemingly extracting DNA from Drac's vampire bats, using it to not only keep the monsters alive, but possibly lobotomizing Phantom and Quasi to keep them fully under control and content? The lore of Darkmoor gets rather grim the deeper you look into it, and it's possibly my favorite thing about the land. They did NOT pull any punches on delivering a proper horror story.
