Son of a Slave

AU. What if Anakin and Obi-Wan's positions had been reversed on Mustafar? After 4-year-old Luke is taken by slavers, Vader begins to dream of a blonde, blue-eyed boy. His long search leads him to Tatooine, where he feels a strong disturbance in the Force. Rage, hate, & a desperate plea for help. There he finds a 7-year-old slave boy, his son. Not dead as one led him to believe.
