Legend has it that in the endless sea, fishermen will occasionally find an island, but they will never reach it. Like a mirage, looming in the clouds and fog.
People who have seen it say that this island is unpredictable, hard to find, and always shrouded in purple clouds. What's even more amazing is that it will continue to move with the passage of time, sometimes as if it is floating on the sea, and sometimes as if it is suspended in mid-air. Therefore, some people say it is a city under the sea, while others say it is a city in the sky.
