Some comments made me reflect on the story and realize that readers can't predict where it will go because they can't read my mind, so I decided to end these thoughts here.
Forget about trading stocks with Muggles and things like that, at most, Rigel can open a shop in Diagon Alley or Hogsmeade or something like that.
Forget about using state-of-the-art ships from the world of Harry Potter or some futuristic world, all the rewards from Pirates of the Caribbean will be used on a Pirates of the Caribbean ship, that's it.
I understand that some readers might see this as a waste, but from the beginning, my mindset is about magic for magic's sake, not a fusion of technology with magic.
I even had some thoughts about adding the Star Wars world, but after seeing this, I gave up because if it went to Star Wars, it would be completely focused on the Force, not on technological equipment and galactic wars. That would displease a large part of the audience that likes the franchise.
I'm not saying this to impose illogical limitations, but it's simply my personal interest in this story, sorry if I disappointed you.
With the plans I have so far, the technological level of the HP world might even regress because of what I'm planning for that world, but how that will actually happen is still undecided.
If you want to read a fanfic about galactic adventure, go read my fanfic of "The Legendary Mechanic". (P.S.: This is definitely not marketing! Absolutely not!)
