The final gathering script (Music doesn't belong to me)

It was now the beginning of the end, the precipice of the final battle when Celestia’s seven lights and Lord Yami’s thirteen darknesses would gather together to leave their mark on fate. The fate of all of Equestria rests on this delicate balance, this struggle for both light and darkness.

Yami: “We’re gathered here today for this momentous occasion: This final skirmish upon Equestrian soil shall determine its conclusion. We shall now decide who keeps this land and who loses it.”

Both Celestia and Yami have shared glares at each other, a serious and stoic one and an egotistical and ambitious one. Both wanted the same thing, yet both had different ideals and views.

Yami: “This land… it beckons to have a new ruler. It beckons for a new era. A ruler like none other. Yes, a ruler who can be ambitious, confident, strong, and has the ability to both usurp and command.” 

Now it was Celestia’s turn to shoot back at Yami.

Celestia: “Yami- no, Starboom. You’ve gone too far now. If those are the only qualities that you think a ruler must have, then you’ve already lost this fight.”

Yami took a short brevity of silence, pondering over why his former name was mentioned.

Yami: “Ah… that name. How I’ve long since rejected it. A name that was to be both dismissed and forgotten. So then, did that old geezer tell you who I was in my previous life then?”

Celestia: “Yes, and just so you know, Starswirl is a lot more than just an old geezer. Such disrespect.”

Yami: “Well, you’re not wrong with that statement. He was the one who taught me everything I know, up to this point. He was once my mentor, but he’s now nothing more to me than a nuisance to my plans. I’m sure you understand, Celestia.”

Celestia: “I do. You’re a heartless monster, one who stepped on everypony that ever tried to help you. Manipulating them for your own benefit, your vessels here are a testament to that.”

Yami only grinned, then chuckled, as if knowing and taking great pride in his way of thinking.

Yami: “My dear Celestia, flattery will do nothing for neither you nor I. And now, our fight shall begin, our vie for this world. Everything shall hang in this balance. And I shall reign a new utopia.”

Yami then assembled his vessels and sent them to charge the Elements of Harmony and Celestia.
