The Hunt for a Time Lord (A Doctor Who, Supernatural fanfiction)

-THIS STORY IS BEING REWRITTEN-

The Doctor is alone once more when he's attacked by strange creatures he's never seen before. He barely manages to escape into his TARDIS. Which led to the TARDIS almost crashing into a parked Impala.
New and old allies, and new and old enemies.
And will somebody please explain why the Doctor's being hunted down by creatures that look like humanoid ravens?
As if things arn't hectic enough...
