N's Castle, sometimes referred to as "The Castle", is the location where Reshiram or Zekrom can be caught. It is Team Plasma's main headquarters, and is owned by N. The Team Plasma Grunt in the Pokémon League Pokémon Center and Looker refer to the castle as Team Plasma's castle. After the events here in Black and White, the castle cannot be visited again. However, in Black 2 and White 2, the player can access its ruins from Victory Road. In these games, its location is unmarked on the map until player visits it.
