"Traveling through hyperspace ain't like dusting crops, boy! Without precise calculations we could fly right through a star or bounce too close to a supernova, and that'd end your trip real quick, wouldn't it?" Han Solo "Sure, you slingshot around the Sun, pick up enough speed - You're in time warp. If you don't, you're fried!" Leonard McCoy Time travel fixit. COMPLETE!
Not a true crossover, but a case of someone using magic to make fiction a reality. And who would that someone be? Who else, but Harry? Alternate Year 5, and beyond. Chapter 7 now available! Chapter 3 fixed!
Harry runs away to America and eventually joins the Air Force under an assumed name. He ends up on SG-20, and is captured by Herur. His host is damaged, so he tries to take Harry as a replacement. Big mistake. Chapter 3 is up.
A thieving Dumbledore, a new teacher, and his own familial inheritance will make for an exciting and dangerous fifth year for Harry James Potter. There're a blue Police box and a red Phone box in the corridor outside Myrtle's bathroom.
Convicted of murdering Cedric Diggory, Harry chooses to walk through the Veil of Justice. Hermione, Remus and Sirius go with him, and because all are innocent, none are killed (save the Horcrux). It sends them away from their persecutors and into a new world, which unbeknownst to them is about to be at war, as well. Harry/Hermione, Sam/Mikaela. Enjoy!
