Percy Jackson and the Olympians: Legends

Atlantis is the location of Poseidon's underwater palace. It is an underwater city inhabited by merpeople and their allies. Atlantis is as big as the city on Mount Olympus, with wide courtyards and columned pavilions. Twenty or thirty buildings are made of abalone, white but gleaming with rainbow colors. Fish and octopi dart in and out of the windows. The gardens are full of exotic sea plants and coral colonies, with luminescent jellyfish drifting about like Christmas lights. It is home to the ancient, isolated, and highly advanced Atlantean culture.
