Not so very long ago, in a castle not so very far away, there was a boy named Tom Marvolo Riddlewalker who went to Hogwarts to learn how to be a Jedi. As Tom grew up, he was seduced by the dark side of the force. Rejecting his Muggle name, he became Darth Voldemort. Gathering a group of Sith Eaters, Darth Voldemort went around terrorizing everyone he encountered.
After hearing a prophecy about an upcoming Jedi, Darth Voldemort went to a certain house and said to Harry Potterwalker, "Harry, I am your father." That news shocked Harry, not only because he knew who his father was (it wasn't Darth Voldemort), he also knew that Darth Voldemort had just killed his real parents.
Knowing that Harry refused to believe his claim, Darth Voldemort tried to use the killing curse on him, but Harry Potterwalker used the Force to deflect the curse. Shortly afterwards, Harry was taken to the planet of Little Whinging and placed under the care of his Uncle Owen and Aunt Beru Dursley and their son Dudley.
Ten years later, Harry Potterwalker went to Hogwarts, where he, Princess Leia Granger, and Ron Weasolo learned how to become Jedis under the tutelage of Albus Dumbleyoda.
