"Okay, this is turning out to be a lot worse than expected. I need to go see Princess Celestia at once!"

Starlight exhaled with great relief, "Oh, good. I really thought you were just going to ignore it all day."

"Oh, of course not! That would be insane. There's obviously something wrong and I need to speak to the princess of the sun," Twilight activated her horn to teleport to Canterlot.

"Wait!—" Starlight tapped the top of Twilight's horn, disrupting the spell. "You weren't really about to teleport in this heat, were you? Do you know how dangerous that is?"

On the border of concern and confusion, Twilight asked, "What is it?"

"If you teleport in anything above 110, you risk disfigurement, missing parts, and/or death. You should know this, Twilight! It's the main reason why Celestia locked the sun's distance in the first place."

Twilight facepalmed, "Oh, right. Well, then I need to leave now! Goodbye, Starlight."

"Good luck."

"Thank you," Twilight darted by Starlight, swung the front doors open, and bolted off en route to Canterlot.

During her flight, Twilight could tell something was not right. Almost arriving in Canterlot, she compared her surroundings since starting. The sun was slightly redder and it was definitely hotter. This could be fatigue from flying or sight alterations from the heat, but the sun looked slightly larger as well.

The spires of Canterlot castle overcame the horizon and elegantly presented themselves to Twilight. These tall and proud towers of regality were surrounded by a transparent red bubble, the same way Shining Armor protected Canterlot on his wedding day. Twilight's mind sped through many different realities, speculating why Canterlot needed protection. Are they under attack? In trouble? Is it to keep the outside out. . . or the inside in? Had Celestia turned into Daybreaker?! Twilight increased her pacing, trying to see Celestia as fast as possible while frantically mauling over every possible situation.

She passed through the borders of the shield and instantly knew what type of protection it was: temperature. The evidence was clear when she entered its barrier, it was a cooler environment compared to the outside. This reaffirmed her fears that her vision of the sun is a very real crisis.

Twilight flew onto the announcement balcony above the plaza. She didn't even spare time to land and instead slid on the smooth marble, transitioning from flying right to a galloping stride. Once in a steady run, she immediately called for Celestia.

"Princess Celestia! Where are you? I need to talk to you!" she shouted while swinging her head in the direction of every doorway.

Her calls echoed around the empty halls, but a reply was never given. The throne room was empty, and so were the meeting room, dining room, and ballroom. Not a single royal guard or cleaning pony in sight, it was desolate. Finally, she caught a glimpse of Princess Celestia in the gardens with her horn activated. "Phew, not Daybreaker," Twilight internally confirmed with a pleased sigh.

"Celestia!" Twilight blurted out with a tone of celebration upon finding her.

Princess Celestia was facing the horizon to the south, but also in front of her was Luna, comforting Celestia and ensuring she remains strong. "Luna! You're here too, good."

Celestia turned around with a look of relief, "Twilight! Thank Me, I am delighted you decided to come. You decided not to teleport either, that was very wise."
