The Battle Chateau is a two-floor facility on Route 7 in Kalos where the player can have battles. The types of Trainers that will appear will depend on the noble rank that the player has achieved through their battles in the Chateau.
The Trainer ranks at the Battle Chateau are inspired by the noble ranks used by many European countries, including the French nobility.
The player starts out as a Baron or Baroness, depending on their gender, and advances through the ranks of nobility by defeating other noble Trainers. In the initial ranks of nobility, the player's rank is mainly determined by their number of wins, with wins against higher-ranked nobles counting for more than those against lower-ranked nobles. The final rank of Grand Duke or Duchess, however, is only achieved after the player has defeated all regular noble Trainers at least once, including Gym Leaders, the Elite Four and Diantha.
As the player advances in rank, the number of Trainers that appear in the Battle Chateau at the same time steadily grows. Any Trainer that is of the same or lesser rank than the player may appear in the Battle Chateau.
Gym Leaders, the Elite Four, and Diantha are also part of the nobility, holding ranks of Marquis or Marchioness and higher. These Trainers will start to appear in the Battle Chateau after the player has beaten them in the main storyline.
Writs[]
As players rise in rank, there will be a greater access to more writs which can be issued by talking to the lady by the front door. Each writ has its own unique effect. All writs expire at midnight on the day that they are used. Several of the writs can be used at the same time. The silver, gold and black writs all stack together, for example.

Trainers[]
A new Trainer will periodically replace one of the other Trainers in the Battle Chateau. This may happen when the player enters the Chateau or moves to a different room, as long as at least 6 minutes have passed since a Trainer was last replaced. If multiples of 6 minutes have passed, multiple new Trainers will appear. If the player is changing rooms when a new Trainer appears, the Trainer will be announced, but if multiple Trainers have appeared, only the most recent person will be announced.
When the Writ of Invitation is active, only three minutes must pass before a new Trainer can appear. When the Silver Writ of Invitation is active, only one minute must pass.
