The RR Station
¥This is the place that Rowling chooses for Harry to wake up in when he has just been zapped by Voldemort with the Avada Kedavra curse and is presumed dead.
¥It turns out that Harry is not dead, or at least he can choose to go back.
¥This celestial version of the King's Cross station is thus some sort of way station between life and death, and it is to this place that Dumbledore comes in order to meet with Harry.
