The Indigo Plateau serves as the capital for the Pokémon League. It is the final destination for Pokémon Trainers competing in Indigo League competitions against the Elite Four. This is the where the powerful Elite Four battle against Trainers in a final showdown of becoming a master Pokémon trainer, who may be challenged after defeating of all eight Gym Leaders of each respective region.
The Indigo Plateau is located just north of Victory Road. The only way to reach the Indigo Plateau is by going through Route 23. However, in order to reach Indigo Plateau by foot, Trainers must venture through Victory Road, a lengthy cave acting as a final test for Trainers.
The Elite Four must be battled consecutively, with breaks to the Pokémon Center prohibited. Trainers are unable to go back or return to previous rooms. The only way to open the door and progress through each room is to defeat the Elite Four member of that room. Each member of the Elite Four is stronger than the previous member, while like Gym Leaders, each specialize in a different type.
