Night 1: Luna

It was only night one, and Luna already felt bored. More so than she had when she had first returned from her time on the moon, and she had been recovering her strength and magic.

At least then, she had a good reason for having nothing to do. With her magic having been severely restricted by the Elements of Harmony, she hadn't been able to perform her nightly duties for some months.

Now though? With the moon taken care of, there didn't seem anything to do. So much so that Luna slumped down in her throne with an annoyed sigh as she looked at the unicorn next to her. "Is it always this quiet?"

Shadow Weaver nodded, looking at her notes quickly. "Normally. If Princess Twilight is able to handle all petitioners during the Afternoon Court, this time is usually pretty quiet. She doesn't seem to mind though."

"Of course she doesn't," Luna grumbled. "So what is there to do? Celestia seems to have handled all the usual stuff. Again. Is there anything for me to do?"

Shadow bit her lip, but she was here to help, and so she turned to a page near the back of a stack of papers before hoofing it over to Luna. "There is one thing. Twilight has been studying the idea of a source of unlimited energy. One that doesn't require magic. She has been looking for an outside opinion on it."

That piqued Luna's interest as she looked over the papers she had been given. It was all written in Princess Twilight's horn work, but she was able to make sense of it. But what it showed looked suspiciously like something she had seen before. "Princess Twilight seeks to use the by-products of baryonic decay as an energy source in a Solar Furnace?"

Shadow nodded, hiding her surprise that Luna seemed to catch on so fast. "Yes. How did you guess that so fast? Most don't get it for a while once they know about it."

Luna rolled her eyes as she looked over the papers again, her ideas confirmed. "Because I have seen something like this before. It is not a real thing of course. But a manga from Neighpon once used the same idea as a virtually unlimited power supply in the story's setting."

And aside from not using it in mobile suits, this was virtually identical to the GN Drive of Celestial Being, Luna thought as she looked over Twilight's various ideas. But there was one major stopping point that she could see. "Twilight has not, as of yet, found something like a fuel source and a way to create the particles needed in the Generation Furnace."

Shadow nodded. "Yes. She's spent so much time looking for it and has even tasked some of our best scientists and engineers to look into it. So far, they have found nothing. Most think it's a hopeless dream of hers. No one has told her that, but most of us that know about this think this is never going to work."

Luna gave the mare a look. "Do you believe as much?"

Shadow nodded. "The idea in of itself is not bad. In fact, I think it's a great idea. But this seems far too advanced for Equestria. We have made great strides in technology in the last five hundred years. But I can't see this ever working no matter how long the princess works on it."

Luna tapped her chin. "How long has Princess Twilight been working on this? I do not remember ever seeing this."

Shadow shrugged. "We don't know. Who can tell with her sometimes? Only the Royal Advisor Spike knows her best, and Princess Flurry Heart when she comes to visit. But she's not around all that often."

Luna giggled at that. That was true enough. "That may be why Princess Twilight has not made this more well known. I have known her for a very long time now. Not as well as my sister mind you. But I have learned one thing about her in all that time. Above anything else about her."

Shadow gave her a hopeful look, unable to keep her own curiosity down. "What's that?"

Luna looked out a nearby window. "It is that Princess Twilight Sparkle will not give up on this dream until she has exhausted literally possibility and avenue of research into making it a reality. Twilight wants this to be real. For this to be her lasting legacy to Equestria and the world, something she can point at with pride. Far than what she's accomplished as a ruler." Luna rolled her eyes as a thought came to her. "Short of asking Discord for help, of course."

Shadow rolled her eyes. Having had to deal with the Lord of Chaos himself on several occasions, she could very well see why Princess Twilight would not ask him for help. "Knowing him, he'd probably make it blow up in her face. Literally."

They both giggled at the idea. Discord would more than likely do it as well if he got the chance. Luna looked again at the papers floating in her magic. "I cannot say how much help I will be on this. But I will do what I can."

Shadow nodded, sighing in relief. "I think that's all Princess Twilight could ask for." She smirked after a moment. "And if nothing else, this gives you something to do during the night, doesn't it?"

Luna nodded, and before long, she was totally absorbed into reading what Twilight had laid out.

Author's Note

In case you're wondering, this https://gundam.fandom.com/wiki/GN_Drive is what Twilight is working on. Nowhere near what Celestial Being had of course. Not yet anyway.

To be clear though. This is not a crossover with Gundam 00. I'm just using the idea for an unlimited source of power for Equestria and the world as a bit of world-building.

Ponies haven't even discovered GN Particles yet. So that is why the idea is where it is now.
