What is special about Mustafar?
We all know about the epic duel that takes place on Mustafar and the consequences thereafter. Im wondering what else is transpiring on Mustafar. We know it's full of lava, ore, and enough artificial structures to allow the duel to cover a large area; so one might conclude given these conditions, there is a good deal of mining and forge work being done on that planet.
Which leads me to my theory that Mustafar is providing a large amount of the raw materials necessary for the creation of the first Death Star.
When we watch the initial portion of the trailer we see several droids travesing the molton surface of the planet, could those be the same droids that "rescued' Anakin? Wouldn't there immediate presence indicate an Imperial presence?
What do you think?
