This late at night, Chryse Guard Security's base was quiet as very few wandered the hallways and those that were awake were mostly on patrol duty around the perimeter.

It was even quieter in the main power room, the only sound was a faint hum coming from the Ahab Reactors of the mobile suit that served as a power source for the whole base.

Some would question why a mobile suit was being used as a battery like this, but it was soon obvious why. The cockpit block was missing altogether, so it was useless as a weapon. What had happened to it, no one knew, and even fewer cared.

No one really knew what it was or even where it came from. It didn't resemble any known mobile suit design in use today. Maruba Arkay had found it out in the desert some years before, but even he didn't know much about it.

Only in the records of Gjallarhorn would something be found as to its identity and history. But no one here would dare ask them about it. Few liked the organization as it was.

Even among Gjallahorn's ranks, few knew about it at all. Only among the Seven Stars was more widely known of the mobile suit, but few really believed their family's stories of war three hundred years gone.

Even the family whose history was tied to the mobile suit now barely thought of it as any more than an old legend, or that it had never existed at all.

For the moment at least, the few in the room paid it no mind. They had grown used to seeing it by now, and few cared enough to look at it. To them, it was just part of the base, no different from anything else in this Earth-forsaken place.

Only one did, a young boy who looked back as he left the room with his friend Orga Itsuka. Something about the mobile suit always seemed to draw his eye, yet he could never explain why. But something about it seemed to call out to him.

He never talked about it of course. No one would believe him, and half the time, he didn't believe it himself. He didn't have many that he could call friends as it was on the base outside of Orga, and bringing this up would make him even more of an outcast than he already was.

And as much as he wanted to deny it, he didn't want that.

For a second, Mikazuki Augus felt something brush past him. But there was nothing there as he turned to look for it, so he paid it no mind.

"What is it?" Orga asked as he turned to see why Mikazuki had stopped.

Mikazuki shook his head as he turned around. "Nothing. Thought I felt something."

Cosmos smiled as she watched Mikazuki and Orga leave. Though no one here could see her, she had left just enough for one to feel her. It confirmed her thoughts as she turned back to look at the far wall.

Walking over to the mobile suit's foot, her smile faded as she placed a hand on it. "How far they've fallen. They don't even remember your name now. Let alone Sunset's. A power battery! This is a new low for any Gundam."

She looked up to the head. Cosmos could see the signs of neglect and no maintenance all over the body. It was sad, to say the least. How it had become so bad, she tried not to think about it. Mankind had not learned it seemed from its near extinction.

She smiled, for she knew that in some way, it could hear her. "They remember her in Equestria. Celestia remembers her still. Her friends made sure of that after the Calamity War." She chuckled. "For her, it's only been thirty years since that day, but she still grieves like it was yesterday."

She rolled her eyes. "Sunset would rip these idiots apart if she could see what they've done to you. It would be worth it to watch. None of the Gundam Frames deserve this fate. No Gundam does. They should all go out in a blaze of glory. Not left to sit here, abandoned and forgotten."

Cosmos looked back toward the entrance, and her smile grew. "Your time is coming again soon. I know it. Mikazuki knows it too, even if he doesn't fully understand it."

That seemed to provoke a response, for the head looked up at her slightly. But it was enough for Cosmos to notice it.

She frowned though. Events were even now hurtling toward the same conclusion as it had been in the Prime Universe in this corner of the multiverse. But no more.

Not if she could help it as she poured her power into her hands and laid them both on the foot before her. Only she could see the glow that soon covered the entire mobile suit.

In a moment, the glow faded and Cosmos removed her hands as her smile returned. Nothing looked any different after all that, but that wasn't the full story as she turned and walked away.

Things had been changed for almost everyone. For the better, she felt. Why she thought to leave this universe the same as the Prime Universe here, she didn't know, but that was of little consequence now.

She had changed just about everything about the future of this universe. Somethings would remain the same of course, but certain events would not follow what had happened before in another universe.

As much as Cosmos wanted to change the present for Third Group, some things had to remain the same. Otherwise, those involved would never become what they were meant to be.

That included not changing a thing about the attack on CGS' base by Gjallorhorn that was soon to come, as much as she wanted to. None of the children here deserved this fate.

The changes would begin not long after that though. Gjallarhorn would never know what hit it when McGillis Fareed launched his coup. And Mars would have its king. There were worse choices than Orga for the role she felt. But there were no better choices either.

She turned back once and smiled. "Good luck, all of you. Makes them proud," she whispered, before fading away completely. Nothing seemed to have changed in the whole room after all that.

But for the first time in over three hundred years, the Gundam Barbatos looked newer in some way. And now it only waited for the right time.

As the memories of a pilot, over three hundred years dead returned to its own memory. Part of Sunset's former magic had leaked into it during her time as its pilot, giving Barbatos more of a soul than what many had thought possible.

And now that soul had awoken from its long slumber.

While Cosmos knew that she had laid the groundwork for the characters in her brief stop with the Barbatos, there remained something that needed to be done to make sure things turned out like she wanted to.

Her first stop? Jupiter. Teiwaz had the knowledge to bring Barbatos back up close to where it had once been during the Calamity War. But they did not have what it needed to bring it back up to 100%

An easily solved problem of course as Cosmos made her way to where the Saisei was currently located. She again wondered how humanity had fallen so low. Sunset and the others had brought it back from the brink of extinction, yet they had fallen again.

It was sad, really. And not a little pathetic as well. Gjallarhorn was partly to blame of course. The organization founded to keep mankind alive had become no better than those from an earlier epoch.

But that would change of course. Even now, her earlier changes were already taking effect on certain individuals. On Mars, and across the entire Earth Sphere and Outer Sphere.

And those who were a complete waste of a character? Well, it wouldn't be like many would miss them in the end anyway. Stupid plot armor in the Prime Universe. But that was easy enough to fix. And she would enjoy watching them die.

Oh, how she would enjoy watching them die. Especially Julieta and Lok. A bigger waste of literally everything about them would be hard to find in many universes. Cosmos almost considered getting rid of them right here and now.

But where was the fun in doing that? It was more fun to watch them squirm as they realized they were about to die, and there was nothing they could do about it.

Cosmos chuckled at the thought as she finally came to where the Saisei floated. Quickly focusing on the task at hand, she wound her way around to where the mobile suit shops lay.

It wasn't too hard to find her way to the main computer room. When no one could even see her, let alone do anything to stop her, it was like taking candy from a baby.

And while she was in the right mood to do just that, Cosmos had more important things to worry about at the moment, as she came before the main terminal. Quickly setting to work, she soon had what Teiwaz had on the Barbatos, and several other Gundam Frames as well, up.

As she had suspected, these specs would allow engineers and technicians to bring Barbatos close to 100% of its original fighting capability and operational standards, but not all of the way there though.

It would never really be what it was when Sunset had been its pilot of course, and Cosmos had no intentions of that, but the modifications she was inputting at that moment, would allow Mikazuki to fight with it in his own way. One that would still be his own.

And at the same time, follow closely what Sunset's own piloting had once been. When the time came for Barbatos' upgrade to its Lupus and finally Lupus Rex forms, it would truly become the Devil of Tekkadan.

This was ironic in a way, seeing as it was named after the Eighth Duke of Hell from the Ars Goetia. Why all of the Gundam Frames were named after demons was beyond Cosmos at the moment, but their names were fitting.

How Teiwaz had this information was not something she could see, but there was little point in knowing that now. That they knew this much at all was all that mattered.

And, in a way, they were all carrying on the proud tradition of the White Devil of the long-ago Universal Century. Zeon might have even appreciated the irony of what was soon to come. Though it was hard to tell if that applied to all or just some.

Gjallarhorn's EB-06 Graze and its various offshoots were in some ways like Zeon's Zaku, but the organization was far more like the Earth Federation's Titans and the Earth Sphere Federation's A-Laws. While Mars and Tekkadan were more what all those who wanted to claim independence from Earth could have been.

But she could not change what had come in the past. Not here in this universe at least, as Cosmos finally finished updating Teiwaz's and Saisei's databanks. Her work here was done now. Now all that remained was to watch as the final drama played out.

She wondered briefly, as she left the room behind if the In-Between Inn had anything going on at the moment. She could use a strong drink after what she had done here, and Pinkie Pie was always up for a good story. Last she had heard from the pink pony, no one had ever come to the Inn from a universe like this before.

And if Rainbow Dash was also there, she would love it even more. She was always up for a good action story. All they had to go by was those fantasy mecha to go by. Time to change that.

They seemed to have a distinct lack of Gundam-related universes where they came from. Why that was, Cosmos didn't know. The others didn't like to talk about why some universes didn't exist in their own multiverse.

If she had to blame it on anything, it was that many more like her had been born mortal, and still held many of their mortal morals and concerns. Cosmos was beyond that of course for she had always been as she was. Mortal had never been a part of her being. Not as the others knew at least.

But that was a whole other story, she chuckled, as she faded away entirely from this universe.

Author's Note

In case you somehow missed it, this is an Iron-Blooded Orphans crossover with Equestria Girls. This series needs more love as it is. Why Sunset Shimmer with Barbatos? Because why not? The main character always gets the main Gundam. That said, all of the Equestria Girls Mane 7 will get their own Gundam. All of them are known and named Gundam Frames from the anime.

And yes. There is a point to this chapter, besides setting up the rest of the story. But you'll have to wait until the end of the story to find out.
