Just to remind all of you, this fanfiction constitutes of a series of random cross-over ideas, and it is not to be taken seriously. This is all a big joke, so don't take it to heart. But if you do like the idea, feel free to write your own fanfiction developing the theme, just remember to mention me and to send me a link so I can read your story too!
Idea 2 – In a galaxy far away
Now that Anna was breathing normally, king and queen could only think about how to control Elsa's power and keep both of their daughters out of harm's way. The old troll explained:
"Wherever she goes, fear shall be hear worst enemy."
"What can we do?", the king asked, and the troll was pensive.
"Perhaps..."
"Perhaps?" The queen urged him on.
"I have a cousin that lives in the swamp. He can teach Elsa to control her fear, and the force that lies within her, but..."
"Please, we will do anything!"
"His training will be harsh, but effective. It will be hard to find him, he's been hiding in the swamp, and he does know how not to be found if he doesn't want to. And, also... he speaks kind of funny."
"Fear brings anger. Anger brings the dark side of the Force. Control your fear you must, or lose yourself to darkness you will."
The king knelt in the green wet soil, both to implore and to be in the same eye level as the green wise gnome.
"Will you help her, Master Yoda?"
"Hard will be the journey. Is she prepared? Who knows?" Yoda now faced Elsa, that was about as tall as him.
The girl felt the frost starting to form patterns over her skin and freezing the swamp water. She looked into the dark eyes of the green gnome and felt calmer than she'd felt ever since the incident with Anna.
"I'm prepared. Please. I don't want to fear anymore."
A couple years later, in the other side of the galaxy.
"Obi Wan Kenobi left instructions on how to find Master Yoda." Lea explained.
"Master Yoda?" Luke asked.
"He was the greatest Jedi Master of his time. He can teach you how to control the Force."
"Will you be safe while I'm gone?"
Lea ignored his protective question. "We'll have to be careful, though. The planet where he hides is primitive. They know nothing about the Galactic Federation, or even the Empire. Many years ago it was agreed that they wouldn't be contacted by the others planets until they were able to develop some sort of technology of their on. Right now they are ruled by 'magic' and superstitions."
Now a couple paragraphs about Luke crashing his ship in this swamp and meeting Yoda for the first time – you've seen the movie. The difference is that this time there is a 13 to 14 year old Elsa by Yoda's side, who's still very shy in relationships with people, but pretty proficient in the use of the Force, light-sabers and mostly has gotten the hang of her own powers.
Then, if you are willing, we can dedicate a few paragraphs to a healthy competition between Luke and Yoda's senior apprentice, Elsa (for example, she can show off by raising his sunken ship from the swamp herself), and they can develop a big brother and little sister relationship. But that only if you are willing. Otherwise we can skip to the conflict right away.
A few months later, in an Empire ship.
"Sir! The rebel Luke Skywalker's ship has been located!"
The heavy breathing that constantly came from the dark helmet got faster, almost excited. Darth Vader gave the order:
"Make preparations for the journey and subsequent capture. Use whatever means necessary, I want him alive."
"But sir..."
The other employees held their breaths, and even the well trained clone soldiers stood straighter. No one said "but" to Darth Vader.
"...sir, the planet is not yet developed, and the Galactic Federation Law states that no intervention should be made in planets that have not achieve space travel technology..."
The man was unable to finish, because he was suspended a couple feet in the air, being chocked by an invisible hand.
"The Galactic Federation is no more, and their law is no longer. There is only the Empire, and I am the Empire."
Darth Vader tossed the now lifeless body aside, and someone else immediately took his place.
"Give orders for immediate departure." The sith commanded. "We shall visit this not-developed planet."
"It shall be done, sir!"
