Opelucid City is where the player battles Drayden in Pokémon Black and Iris in Pokémon White. In Black it's technologically furnished, and in White it's historically furnished. Also there is a battle house in this area. In White this will be a Triple battle house while in Black there will be Rotation Battles. You can face the two trainers in the house once per day. In White the Trainer on the bottom floor will have Simisage, Simipour, and Simisear in that order. Also there is a house that asks for a Pokémon from the opposite version that you are playing with the move charge. It is said that he can turn the city into the other verison. History or furnished. After you've acquired the Legend Badge Professor Juniper will talk with you once you head outside. She will say some things then she will give you a Master Ball.
