History[]

In Pokémon Moon and Ultra Moon, it is just a simple lake that can be accessed in the Route 17 that once was the original location of the Sun Flute, however, in Pokémon Sun and Ultra Sun, it can be accessed in the reverse world through an Ultra Wormhole opened by Solgaleo or Dusk Mane Necrozma during the night or by Lunala or Dawn Wings Necrozma during the day. After arriving in the lake in Pokémon Sun and Pokémon Ultra Sun, if the player character has a Solgaleo in the party, the Sunne Pokémon will encounter Lunala and they will create a Cosmog, who joins the player character's team.
