In a similar vein to Grandmaster Galaxy from Super Mario Galaxy 2, Special 8-Crown from Super Mario 3D Land, or Champion's Road from Super Mario 3D World, being the final level, this kingdom is the biggest challenge found in the game, with the only Power Moon being found at the end of a gauntlet of challenges based off ones previously found within the game. It is accessible once the main game is completed and 500 Power Moons have been obtained. This is also served as the seventeenth and final kingdom overall in the game. The Darker Side of the Moon is a secret kingdom in Super Mario Odyssey, and is the greater location of Culmina Crater.
