Atlantis is a legendary city that people say sank into the ocean a long time ago. According to the stories, it was once a beautiful island with grand palaces, shiny temples, and advanced technology. The people who lived there were very rich and powerful, but the old legends say they became greedy and behaved badly, which angered the gods.
