Nameless Cavern

The Nameless Cavern is a location in the Hoenn region, found on the northeast side of Sootopolis City in Pokémon Omega Ruby and Alpha Sapphire. It is only accessible by soaring on Latios / Latias and appears when the player has three Pokémon with maximum friendship on their team. The Cavern's interior is highly reminiscent of the Cave of Being, which itself is reminiscent of Verity Cavern, Valor Cavern, and Acuity Cavern.
