There was only the one elf vampire in that one, the main character Jander Sunstar. He was very much a noble good guy (ironically a follower of the elven sun god in life) who was turned into a vampire. He was pitted against who is arguably THE vampire antagonist in D&D lore, Strahd Von Zarovich (so good vampire vs evil vampire…which was refreshing in itself since D&D vampires typically suffer from the chronic ‘all this race are chaotic evil syndrome’, so having one in that setting who was fundamentally still a good guy was refreshing.
