Title: Clarke's Third Law
Summary: Any sufficiently advanced technology is indistinguishable from magic. So what happens when witch meets scientist, and each tries to teach the other about their brand of magic? Things become a tad confusing. And more than a bit fantastic. Doctor/Rose
Disclaimer: I don't own Doctor Who or Harry Potter. I can only dream...
Note: Tags to Doomsday and The Runaway Bride. This is the last chapter! I'm already working on the sequel, so stay tuned!
