Percy Jackson and the Olympians: Legends

Ogygia is a phantom island that exists everywhere and nowhere. It was designed as the prison for the nymph Calypso, daughter of the Titan Atlas. It is a very gorgeous place, where there are invisible servants and a beautiful garden, made by Calypso herself. One of the garden's plants is moonlace. Its terrain is mostly grass-covered hills with pristine beaches all along the edges, though it has groves of cypress tree. It is apparently not very big as there were few places Leo Valdez could go and not see the ocean.
