In Blood Builder, you'll feed on unwary travelers. The villagers, however, know exactly what you are, and they're not scared because they're under the protection of their master, Dracula. Two of those villagers, and the most important, are Dracula's familiars, Albert and Ana.
Albert is Dracula's most trusted familiar, and he's the steward of Dracula's Castle. Despite your status as an immortal, Albert doesn't think you're worth even his time, considering who is master is, but Dracula's command was clear; Albert is to assist you however he can.
Ana manages the inn during the day. Unlike her husband, Albert, she's excited to have an immortal overseeing the village again, even if it isn't their master. Her can-do attitude is the only thing that has kept the inn open despite a war and years of neglect.
