Typical characters include the vampires, which may have different clans with their own unique characteristics. For example, one clan might be more stealthy while another is more brute - force. The villagers will have a variety of personalities too. There could be a skeptic who doesn't believe in vampires until it's too late, a love interest for the protagonist, and a group of outcasts who end up being crucial in the fight against the vampires for various reasons.
In a vampire village novel, you'll often find a young, headstrong protagonist. This could be a villager who has a personal vendetta against the vampires, maybe because a family member was killed. There are also the vampire lords or leaders, who rule over the other vampires and are usually very cunning and powerful. And don't forget the local priest or shaman - like figure who tries to use spiritual means to combat the vampire threat.
