Let's play a text-based adventure game. I'll be your guide.

You are a adventurer needing to get to Atlantis. You have a few problems: one you're a human and can't go underwater for much time, two you are human and only merfolk are allowed in Atlantis, three you are human and can't pass their checks. There is hope though others have made it in if you find out how others have you could get in too.
