Pokémon Brilliant Diamond and Shining Pearl have a feature called The Great Underground. This is a souped-up version of the Underground feature from the original Diamond and Pearl games on the Nintendo DS. Basically it’s a way to get different kinds of Pokémon and items. To access The Great Underground, you have to use the Explorer’s Kit item, which you get once the story takes you to Eterna City.
