Origin of Solar flame

Many years later, Twilight, Solar, and Spike were living one of the castle's towers. Spike was old enough to walk and talk, while Solar still had not gotten her cutie mark yet.

Spike and Solar were preparing for a party that Twilight's Canterlot friends were setting up. Spike was holding a present in his claws walking to the door with Solar right behind him when Twilight burst through the door, knocking him away.

"SPIKE. Are you okay?" yelled Solar.

"Yeah, I'm fine." he replied.

"You need to be more careful Twilight. Spike could've gotten very hurt."

"Solar, do you know where the book on Predictions and Prophesies is?" Asked Twilight, clearly ignoring what she said.

"No, I don't." Replied Solar, annoyed.

"It's over here." Said Spike, before getting pulled off the ladder and crashing on the floor.

"Seriously, Twilight. That's the second time you could've hurt Spike since you came back."

"Spike, send a letter to the Princess." Said Twilight, ignoring Solar's complaint again.

Twilight got the message sent and was expecting Princess Celestia to respond with a way to prevent Nightmare Moon's return directly. However, she got a command to go to Ponyville to oversee preparations for the Summer Sun Celebration and to make some friends. But Twilight ignored Princess Celestia's order to make friends, believing that the fate of Equestria did not require that.

"Twilight, if Princess Celestia wants you to make friends, you should do it."

"Ugh, Solar, I already said that the fate of Equestria does not rest on me making friends. So just drop it."

Soon they arrived in Ponyville just as a pink earth pony was walking towards them.

"Hi." Said Solar.

Suddenly, the pink pony rushed off somewhere, leaving the three of them standing there.

The first thing on the list was to taste the food at Sweet Apple Acres. When they got there, they heard the sound of a farm pony. They looked to the right and saw a orange pony running towards a apple tree before turning around and bucking the tree.

"Hello." Said Solar, " My name is Solar Flame, and this is my older sister Twilight and my younger brother Spike. We're here to check on the food, it sure smells good."

"Well, howdy. My names Applejack." Said Applejack. "I'm sure that it will taste better than it smells. Wanna try some."

"Sure." Said Solar

Applejack gathered all of her family visiting from all across Equestria together for them to taste the food. After they were done, they were about to leave when Applejack's younger sister Apple bloom asked if they would stay for brunch.

"Well, we have a lot of thi--"

"Of course we will." Said Solar, cutting Twilight off. The entire Apple family cheered while Twilight groaned.

A few minutes later, Twilight, Solar, and Spike left the farm to check the other things on the list. Twilight was stuffed, while Solar was fine, despite eating twice as much food as her.

The next thing they had to check was the weather, which was run by a pegasus named Rainbow Dash. Twilight looked up at the sky, which had clouds in it, before mentioning how bad of a job she was doing.

Suddenly, Solar felt a weird feeling telling her to duck. She did right when a blue pegasus with a rainbow mane crashed into Twilight, sending her into a mud puddle.

"Hey, work on your flying." Yelled Solar.

"Sorry." Replied the pegasus. "Anyway, I'm Rainbow Dash. Heard of me?"

"I heard that you're supposed to be clearing the sky for the Summer Sun Celebration." Said Twilight

"Ignore her, I'm Solar Flame, this is Twilight and Spike. We're just checking on a few things for the Summer Sun Celebration. We just came from checking the food, now we're checking the weather, but so far it's not done.

"Yeah, I know. I'll do it after I rest for a few minutes. I've been training to join the Wonderbolts, but the training drained me almost completely."

"Alright. Come on Twilight, we've got more things to do."

"Just give me a second." Replied Twilight, shaking the mud out of her mane.

"Hey, wait a second." Said Rainbow Dash, noticing how Solar had no cutie mark. "How come you don't have a cutie mark, everypony has a cutie mark when they're your age."

"I don't know what my special talent is yet." Replied Solar, still walking away.

The next thing on their list was decorations. The three arrived at the Ponyville Town Center, finding a white unicorn mare with a purple mane decorating the building.

"Excuse me." Said Solar

"Just one second." Replied the unicorn.

"Take your time."

"So, what have you come for."

"First, my name is Solar Flame, this is my sister Twilight, and my younger brother Spike. We're just checking on the decorations."

"I'm Rarity, and -- Oh, my, you look amazing darling. The space themed bat wings ending in the fiery colors, the blue and green mane and tail, the white unicorn horn with the gold swirl, the rainbow eyes, the unusually empty flank. Wait, why don't you have a cutie mark yet."

"I don't know what my special talent is yet. Anyway, we have one more thing we have to do before the celebration. See you there Rarity."

"Last thing on the list is music." Said Spike

They suddenly heard the sounds of several birds. They looked and saw another pegasus with a pale yellow coat and a light pink mane in front of a tree with many birds on the branches.

"Hello" Said Twilight, startling the pegasus and her birds. "We're here to check on the music."

No response came.

"Let me handle this Twilight." Said Solar, coming out of the bush. "I'm Solar Flame, this is Twilight and Spike. What's your name?"

"I'm Fluttershy"

"Fluttershy, that's a nice name."

"How did you know that was what she said, she was so quiet." Said Twilight

"I somehow adjusted the sensitivity of my ears." Replied Solar.

"Your birds are back Fluttershy. We'll just be leaving."

Fluttershy looked over at them just as Spike came out of the bush. She got super excited and rushed over to meet him.

Fluttershy ended up following them to the Ponyville Golden Oaks Library, listening to Spike tell her about his life. Right when Spike ended the story, they arrived at the library.

"Well, we're here. See you at the Summer Sun Celebration, Fluttershy."

The three walked into the library and found that the lights were off.

"Um, what's going on?" Asked Solar, just as the lights turned on, revealing a bunch of ponies.

"SURPRISE!!" They all yelled.

Then the pink pony they saw when they first came into Ponyville appeared.

"Hi, I'm Pinkie pie. I threw this party for you three."

"Well, I am surprised." Said Solar, not noticing that Twilight left the room.

Solar played many games with the other ponies until it was time for the celebration.

Twilight, Solar, and Spike walked over to the Town Hall, only to have the celebration interrupted by Nightmare Moon. She had kidnapped Princess Celestia and was planning to bring eternal night on the world.
