This is a floating island with a temple crowned by a tentacle-faced statue. At some point three hundred years ago this place became so holy and full of prayers to this weird monuments, so it got detached from the Earth’s surface and floated away. Centuries later, when it declined a bit and technologies allowed to build a flying sci-fi ships, first explorers approached the island to rediscover it.
