The Legend of Lental

About two thousand years ago, a meteorite threatened to crash into Lental. The luminescent Pokémon are said to have appeared then and passed their energy on to all the Pokémon of the region, creating a barrier of light that protected it. The people of the time painted murals and built temples, now in ruins, on every island. A century before the game, Captain Victor explored most of the islands and recorded his discoveries in a book, Adventures in Lental.

Lental is the only region where Illumina can be observed, making Pokémon and Crystabloom shimmer. The French names of the islands all come from Greek.
