Welcome to Atlantis, our haven. Yes I know Atlantis disappeared years ago. But we lived, and now we have tails, like a fish's, dolphin's or eel's. The future leader has been born with a golden eel tail. Only one has been born.…until Mateo and Posiden were born. They both have golden eel tails, and both want power. They will soon clash, water versus water, and the swords will clash. Now they're recruiting all Atlantis citizens to join them. You are a normal person until they become 20. Then they fight. Who's side are you on?
