The Three Races

There were two races monsters and humans, that's what all the monster history books say. Humans don't even remember monsters. Though neither races remember the third race, that could be monster or human. Vampires. Only told of in fairy tales. They are forgotten, almost extinct. Almost, only one vampire remains. They live in the Underground, with the secret of what they really are hidden from everyone else. The vampires' name, is Sans.
