It is the summer after the Triwizard, Harry's own ignore him. His friends have forgotten him. He has only received one letter stating they are together. Cedric is dead, and Voldemort is back. He is left alone and forgotten. Feeling sorry for himself, he curls up and cries. A blinding explosion of magic erupts from the smallest bedroom of #4 Privet Dr. and Harry Potter vanishes.

Harry's been feeling like something was being kept from him for a while... he just didn't expect the goblins to be the ones to rescue him from the Dursleys and explain. Bad Dumbledore, good Snape, slightly manipulated but still good Weasley's.
