Entrance

When the player enters the hallway north of the PC, a Cipher Peon will drop from the ceiling and battle. If the Peon has a Shadow Pokémon that the player has not yet Snagged, it can be Snagged here. After each fight, the player will need to exit and enter the floor to trigger the next one to appear.
