A/N: I own absolutely nothing, have never written anything Doctor Who related before, and apologize profusely for the short prologue.
Looking back, no one involved could possibly have guessed that such a seemingly ordinary night could have led to something so extraordinary. The only thing that everyone agreed on was the location. For everyone, a tiny flat in the Powell Estate had been the site of great discovery, of meetings and rebirths. To some it was home. To others, the quiet sanctuary after a long adventure. On this night it was the center of a mystery, a place where great people united and reunited. For in that tiny flat lay a secret. Like many secrets it was glaringly obvious, yet unobtrusive at the same time. It was a crack. A simple crack in the bedroom wall of a young woman, who at the present time lay sleeping in her bed. Whlie aware of the crack she was unaware of its origins, its secrets, its dangerous possibilities. That is, until she was awakened at 2 AM by a knock at the door.
