The games take place in Unova, though the landscape has changed drastically. Two years have passed since the original Black and White, so part of Unova is now covered with ice, and certain locations have been added or altered. For instance, Route 4 has been retouched, and Challenger's Cave has been removed entirely. There are other new locations as well, like Hiougi City, the starting city in the game, which features a Pokémon Center as well as a trainer school.
