Atlantis
Appearance
Atlantis (Ancient Greek: Ἀτλαντὶς νῆσος, "island of Atlas") is a fictional island mentioned within an allegory on the hubris of nations in Plato's works Timaeus and Critias, where it represents the antagonist naval power that besieges "Ancient Athens", the pseudo-historic embodiment of Plato's ideal state. At the end of Plato's story, Atlantis falls out of favor with the gods and famously submerges into the Atlantic Ocean.
