Two weeks later, the Summer Sun celebration was underway! And it was, to Twilight, very stressful.

Keep it together, Twilight. You got this.

For you see, now that Luna and Celestia had retired, it was Twilight's first Summer Sun Celebration in which she had to raise the sun and lower the moon herself. Of course, with the weekend beginning, who should be at her side but Rainbow Dash and Applejack. Well, mostly Rainbow Dash. Applejack was off selling cider somewhere in the fairgrounds.

Ponies from all over, from Ponyville to Manehattan, attended this year for its historic significance. It was their first time seeing someone besides Celestia raise the sun, so naturally ponies would be in an uproar. They weren't mad, mind you. They were simply excited.

Twilight Sparkle stood on one of the castle's many balconies, looking over all of the guests that had just arrived. And there, in the distance, she spotted a familiar white and purple pony. Flying out of the balcony, she called, "Rarity!"

Rarity smiled up at her fellow princess. "Twilight! How are you?"

"Great now! How was the gala?"

Rarity's eyes twinkled as she regaled Twilight on all of the past week's "stunning dresses" and the cast of Hamareton's "mind-blowing performance".

"Well, I'm glad you had a good time, Rarity".

"And what about you, darling? How was your week?"

"Paperwork. Lots of paperwork. As well as a package from-"

"Oh, I almost forgot! I brought somepony special with me! He's here somewhere- oh, there he is! Lin! Lin, come here!"

"Wait, you mean, the Lin Manuel Mareanda is here? How did you manage that, Rarity? He's a busy pony!

"Oh, well, he was one of the main guests of the gala, because of Hamareton being there, you know, so of course when I met him I just had to bring him along with me to meet you! You always talked about how much you liked Hamareton!"

"Actually, that was you who talked all the time about Hamareton, so-"

Twilight was interrupted by a tall stallion with a black goatee and cropped hair trotting over to the two friends.

"Oh, hi! You must be Princess Twilight Sparkle. It's an honor to meet you, your majesty", Lin exclaimed, bowing before the two princesses.

"Oh...we don't do that here", Twilight told him. "Welcome to the gala, Mr. Mareanda!"

"Please, just Lin. You know, I can't believe I am actually here! I've been trying to save up to buy a ticket, but I just can't seem to get one!", the composer replied.

"Gee, that sounds familiar", Rarity remarked.

"What?"

"Oh, nothing, Mr. Mareanda. Oh, there's Sweetie Belle with her crusader friends and Applejack at the cider stand! Twilight, if you'll excuse me...." Rarity walked over to the stand, leaving Twilight and Lin standing in awkward silence.

Twilight broke the silence. "Well, it was nice meeting you...I have to get to the stage. It's almost time for me to raise and lower the sun and moon!"

Just as she was about to take off, Lin stopped her. "Can I give you a word of advice?"

"Oh...sure! What is it?"

"Don't stress out all the time. Be more chill".

Twilight was confused. "Wait, how did you know-"

"That you're stressed out? It happens to many celebrities, Princess. You're no exception".

"What are you talking about? I'm no celebrity."

"You're known by many ponies, correct?"

"Well, yes."

"Thus, you are a celebrity. Just try to relax, and remember, if you fail to do the task everyone is here to watch you perform, that's just one failure. Don't give up just because you fail a few times, okay?"

"...okay...but I don't give up!"

"Never?"

"No."

"Not even once? You're never worried you might fail?"

Twilight was starting to become annoyed. "Look, Mr. Mareanda, it's been nice meeting you, but I have a job to do. Now, if you'll excuse me..."

As Twilight flew off, Lin Manuel Mareanda looked on, his eyes glowing a familiar green. Twilight, however, didn't notice this.

Princess Rainbow Dash stepped onto the stage. "Good morning, everypony! Welcome to the Summer Sun Celebration!"

The place was filled with excited hoots, hollers, and stomping of hooves.

"Now, as we all know, Princess Celestia and Princess Luna used to work together to bring day and night to an open and close, every single day. But now, they have retired, and left that hard task up to somepony else. Mares and Gentlecolts, give it up for my friend, the totally awesome Princess Twilight!"

Everypony cheered as the purple princess walked onstage. Nopony in that festival, however, was more nervous than Twilight herself. She took a breath, and, closing her eyes, imagined herself lifting the moon Cold magic rushed through her conciousness and being as she lowered the moon. Everypony began to cheer as the moon was lowered. Twilight opened her eyes, and smiled. Oh, there was still the sun! She closed her eyes, and began to imagine the sun, that she was raising it, and-

She was suddenly overcome by a horrible burning sensation, the likes of which she had never felt before! But she had to keep going. She felt the cold magic running through her being, only to suddenly flare up very suddenly. She screamed in agony...but she had to....She had...to raise...the sun....she couldn't fail Princess Celestia...not again....

Everypony cheered with relief and concern as the sun came up over the horizon. Twilight opened her eyes, her magic and mind still burning from bringing the sun up. Everything hurt so bad. But that was the last thing Twilight remembered before she blacked out.

The audience gasped as Princess Twilight collapsed. Rarity and Rainbow Dash, seeing from the balcony and front row that their friend was out, rushed onstage.

"Oh my! Is she going to be okay, Rainbow?"

"Yeah, she has to be". Rainbow began to shake Twilight awake, but pulled her hooves back suddenly. "Ow! She's burning up! Really bad!"

"What do we do?"

Rainbow, though usually quick to make brash decisions, had proven herself to be much more calm under pressure and emergencies since she took over teaching at the School of Friendship. She turned to Rarity. "Go call an ambulance. Now."

Rarity nodded and flew off to the hospital. Rainbow, meanwhile, turned her attention to the ponies gathered here. "Attention, everypony", she began, "The Summer Sun Celebration is over. Please, leave out the nearest exit, and remain calm."

Everypony looked at each other in confusion, before somepony shouted at Rainbow, "You're not Princess Twilight! You don't have the authority to-"

Rainbow flew straight up, her voice strong and commanding.

As one of the six princesses of Equestria, I am asking you to please, go home. Now.

Everypony began staggering home, leaving Rainbow onstage with the slumped-over form of Twilight, and Applejack rushing to her, with Sweetie Belle, Scootaloo, and Apple Bloom close behind.

"Rainbow! What just happened? Ah saw everythang from the stand! Is Twilight alright?"

Rainbow looked up at her. "I...I don't know".

Rarity flew back in. "The ambulance is on its way".

The three friends, as well as the Cutie Mark Crusaders, stood guarding Twilight until the ambulance arrived.

Author's Note

I know this is kind of a dark way to end the chapter, especially when the fanfic has only just begun, but I don't plan on making this a very long story. I might. If I do, great.

As always, let me know in the comments what you liked/disliked, and what I can do to improve the next chapter!

God Bless!
