the only maps I know of are Lonely Cave, Cape of Distant Worlds, Fluorite Plains, temple of dreams, South Pole, Atlantis, Last Cave, Ficho tunnel, bonfire island, Ascension Island, and Sky's Rim.
However when you hover your mouse over the far-right side of the screen on the website it obviously shows how many people are in which world, and I see worlds I've never been to like California Island, Forest of Lights, Slough Creek, Water Mill, etc. How do I get to these maps?
