All you remember was being at a vampire them festival, where you met this group that looked like vampires yet they told you they were the musical actors so you trusted them. They invited you out to the forest were they knocked out before you heard them telling you, "no hard feelings...you'll understand" this group was actually part of a cult where they worship Dracula or whatever vampire count they worship, so in their twisted thoughts If they found a pure and rare blooded man or woman for a bride or groom, he will grant them immortality

When you wake you, you were being taken to a dark old castle in the woods and brought into there as they began setting up the ritual
