Vampires were known to coexist with other organisms but just far out. Unreachable. Far from the actual society.

You just so happened to go on a camping trip with your friends to a forest not too far away but, they thought it was funny to leave and hide and have you looking for them.

That ultimately led you to a very... Interesting palace looking place. The architecture was gothic, like one of those old cathedrals.

You looked through and didn't find anyone but then you could hear the sounds of a piano playing from the ballroom.
