There are millions of planets inhabited by humans. The Wizarding World of Harry Potter helped drive attendance at Universal parks up by 80 percent in the six years after its opening. In the A New Hope radio dramatisation it was suggested that the goods were rare metals.

But unfortunately for our heroes, Han and Leia's emo son is after the map as well, and once he finally comes out of his bedroom, nothing will stand in his way.
