You were skeptical, especially when your friends told you about the flooded city of Atlantis. To you, it was just nonsense.

One day, your friend read on the Internet that the entrance to Atlantis is in a cave in the Caribbean. You resisted this wild idea to the last, but you were broken into this one.

A couple of weeks later. Your friend got lost in the cave, and you continued to explore deep into your side of the cave until you saw a bright light through a crack in the darkness. You managed to squeeze between the crack and what you saw shocked you.

It was like a parallel world underground. Large trees, sky, animals, water and buildings of incredible beauty. It was also bright, as if there was a sun underground.
