|South Exit: Eterna City
The Eterna Galactic Building is the headquarters of Team Galactic within Eterna City. This multi-story building initially holds lots of Team Galactic members. It is first accessed in order to save Rad Rickshaw's Clefairy which got stolen by Team Galactic. It has some aesthetic changes between Diamond & Pearl and Platinum.
In Pokémon Platinum, a new room is found just off of the main reception. This room is where Charon did experiments with the Pokémon Rotom and allows you to change Rotom's form at will
