What I mean is, if you could have any fantasy, sci-fi or otherwise race "come out of hiding" now, which would you pick, if any at all. A few examples would be hobbits or dwarves emerging from underground after hiding for many millenia, elves coming out of the woods and making themselves know, aliens from some scifi movie/game or well, vampires coming out of the closet.
Any race is fine as long as it's just one race or none at all of course and also explain why.
