Possible Titles: Ponies Versus Prometheans; New Quest For The Mane Six; The Didact's New Mission; Celestia's Plan

Premise: MLP: FIM. Halo. The Prometheans arrive in Equestria following their master. But for unexplained reasons, The Didact is unable to control them, and they continue their mission of eliminating and digitizing all living beings. Luckily, Princess Celestia has a plan to stop them, which she explains to the Mane Six.

Personal Comments: I've been thinking more about the Didact in Equestria idea I had a while back. Feel free to adopt this idea if you want, all I ask is that you give me credit in the summary or author's note.

I thought of a general plot. He may stay in Ponyville rather than Canterlot, and befriends the Mane Six, and aids in their adventures and lessons, maybe learning about friendship himself and having second thoughts about his mission.

He also befriends Doctor Whooves and Derpy, who start working on a machine to reunite him with the Prometheans. He also helps on their other projects maybe. Eventually, his circle of friends learn about his mission, and there may be some tension during that moment, but after a while, they decide to accept him, especially once he shows that their time together has changed him.

And then I thought of maybe in a really emotional story arc, Didact discovers that something bad will happen if Whooves and Derpy use a machine that the three of them built together, so he would crush it with his force, much to Derpy's horror. This would be a lot like the scene in Wreck-It Ralph when Ralph destroyed Vanellope's candy kart. And then this scene would end with Derpy, now in tears saying "You really are a bad guy."

I was thinking that the mane (pun intended) antagonist for the story would either be Tirek or King Sombra. There would be one story arc in which said villain comes around and tries to take over Equestria, but the Mane Six, with help from The Didact, manage to stop him.

If they decided to use Tirek on the show, I imagine he would be voiced by either John DiMaggio (who is pretty close to Victor Caroli from "Rescue at Midnight Castle") or Kevin Michael Richardson. I imagine he would use his rainbow of darkness to take hold of some ponies or other creatures in Equestria and turn them into horrible monsters that act as his minions. By the end, Twilight and her friends would have to use the magic of friendship and the elements of harmony to break his grip and defeat him.

There would also maybe be a subplot in my story about Master Chief and Arbiter joining forces once again as the humans and Sangheili (good covenant) try to battle the forerunners. And the Prometheans make their way to Equestria to regroup with The Didact. And then the final story arc would be about the Prometheans invading Equestria. From there, I'll post a few chapters here to explain. Just some of them that came to me.

I shouldn't really be using my time for this. It's just that it started burning in my head last night. Really busy with my studies. Still have a hard time concentrating sometimes, since sometimes I feel a little anxious or lonely, or feelings that I should be doing something else, and of course you got things like this popping into my head, sending me off into the daydream zone.

Canterlot was in chaos. Ponies were running all around in panic while the guards and wonderbolts trie to protect and evacuate them. Their magic held up well against the shiny invaders and their weapons, but for how long? Buildings were already starting to crumble, the fallen bodies of ponies were starting to clutter on the streets, along with an occasional fallen Promethean.

It was not only Canterlot that was like this; several more cities and settlements all over Equestria were being hammered down by the Prometheans.

Twilight and her friends were inside the palace, quickly following Princess Celestia down the hall, like she had asked. Luna could be seen outside fighting alongside the guards.

"Well, hope you're happy, Dido!" Rainbow Dash spat bitterly at The Didact. "This is all YOUR fault! You brought your little friends here, and now you can FINALLy continue your mission!

"I have already apologized," The Didact replied. "This was not my intent. And even now I do not understand why they do not obey me. If I could stop them now, I would."

Rainbow turned away from him. Under her breath, she silently muttered "I wish I never saved you."

"Stop arguing," Twilight said. "We'll find a way to stop them, right Princess?" She turned back to her mentor, who had stopped by her throne.

"Yes," She said. "There is a way to stop them." She levitated her crystal from its mantel. She shot a light into it, and it presented a projection of a mountain. The land surrounding the mountain was covered in the silhouettes of dark, evil-looking creatures.

"Luna and I had prepared for a moment such as this," Celestia continued. "I was beginning to think we'd never have to use it. This is Starlight Mountain, located far to the east. Many years ago, Luna and I had prepared a powerful magical artifact that once activate, should sweep all through Equestria, purging the world of all things wicked for a short time. It would eradicate invaders and restore the love and harmony within everyone else."

Everyone watched as a bright light shone from a cave in the mountain, and swept across the land, causing the demonic figures to vanish.

"How do we activate it?" Twilight asked.

"You must take the elements of harmony to the tomb, and place them inn this special socket we designed for them," Celestia replied. "Go get the elements now, then find the fastest possible way to the mountain. We will stand up against the Prometheans as long as we can!"

CRASH! As she finished that last word, the glass windows behind them shattered. Everyone turned in horror to face three Promethean Knights. They raised their guns and shot at them.

Celestia shot in front of them, and summoned a force field, blocking off the shots. The guns were still powerful, and caused ripples in the field with every shot. Celestia struggled to hold it.

"You all know what you must do! Go! Hurry!" She commanded.

The Didact rolled out from the field. He threw his two arms out, force-gripping two pillars, and brought them down on the Knights, crushing them instantly in a couple clouds of sparks.

Celestia dropped her field. The ponies all ran out to follow The Didact.

The Didact levitated one gun from a fallen knight to himself. He knew he would need it.

"Let's go!" He barked at his friends. "We must make haste!"
