Origin of Solar flame

When Twilight, Solar, and Spike get back to the library, Solar puts Spike to bed while Twilight searches the library for a book about the Elements of harmony before Rainbow and the others come in.

Twilight explained to them about her real goal while in Ponyville and that she knew a way to stop Nightmare Moon. She also said that she needed the elements of harmony to do that, but could not find a book for it. Suddenly, Pinkie is heard reading the title of a book on the Elements, surprising Twilight.

Twilight began to read the book. "There are 7 elements of harmony, but only 6 are known. These are generosity, loyalty, laughter, kindness, honesty, and trust. When a spark is produced, the 7th element will appear. The last known location of the elements is in what is now-"

"The Everfree forest."

Twilight wished to go in with just her and Solar, but the others(Solar included) refuse. Solar states "Twilight, I think that you should just trust these girls like I do. Besides, there may be something in this forest that we can't do alone."

Twilight, though irritated, accepts the help of the other five.

After walking through the forest for a while, the ponies came to a large cliff. Suddenly, the ground broke up. Rainbow Dash picked up Pinkie and Fluttershy bit onto Rarity's tail.

Applejack and Twilight were still sliding towards the edge, with Solar overhead. Applejack reached Twilight, who was already at the edge, and grabbed her hooves to keep her up.

Applejack looked above Twilight before telling Twilight to let go. Twilight was unsure if she should when Solar appeared behind her carrying Rarity to the ground.

"Twilight, trust Applejack. She knows what she's doing." Said Solar.

Twilight looked at Solar and nodded, closed her eyes, and let go. While she was falling, she was grabbed by Rainbow and Fluttershy, with Applejack jumping on the rocks sticking out of the cliff to get to the bottom. Soon, everypony reached the ground safely.

As they were walking, they heard a roar. In front of them was a angry manticore. Everypony except for Solar and Fluttershy were trying to attack the manticore. Then Solar got in front of them

"Stop." She yelled, "I think we should let Fluttershy handle this, she is good with animals, after all."

"Thank you Solar." Said Fluttershy, walking up to the manticore.

The manticore was about to attack her, but she calmed it down. It opened it's paw to show a large thorn stuck inside.

Fluttershy pulled the thorn out, making the manticore roar in pain. Then it started to lick Fluttershy before running into the forest.

"Told you." Said Solar to the other 5 ponies.

They kept walking for a while. Soon the trees blocked out the light, making it super dark.

The trees started glowing, with menacing faces on them. Everypony was terrified, except for Pinkie and Solar. Pinkie was laughing and making silly faces at the trees, and Solar saw her and trusted that she had a good reason for her weird behavior. Then Pinkie started to sing, which somehow made the faces on the trees disappear. She was quickly joined by the other ponies. When all the faces had disappeared, the 7 ponies laid on their backs laughing before continuing walking towards the castle.

Later, the ponies came to a river, which was super dangerous to cross because a sea serpent was causing the water to be wavy. He was upset because half of his mustache was sliced off. The ponies complained that the serpent, who had the name Steven Magnet, was being too dramatic. But Rarity agreed with his complaints and pulled one of the scales off of Steven and used it to cut her tail to replace Steven's mustache, everypony except Solar questioned Rarity's actions. Solar, however, trusted that Rarity knew what she was doing. Steven was thankful that his mustache was restored and used his body for a bridge for the ponies to cross the river.

They quickly got to the bridge that would help them cross the chasm and arrive at the castle. Rainbow flew over to the other side in order to fix the bridge. The group had slight thoughts that she would abandon them, but Solar trusted her to fix the bridge.

On the other side, three figures, which Solar instantly detected as bad guys, were talking with Rainbow. One of them blocked their view with mist so that they wouldn't interfere. The others grew nervous, but Solar still didn't.

One minute later, Rainbow flies through the mist, revealing the now fixed bridge. The ponies walked across the bridge and up the stairs to the castle. Inside, Rainbow, Fluttershy, and Solar lifted six circular stones off of a large stone object in the middle of the room. Then everypony left the room so that Twilight could try to summon the 7th element.

Solar suddenly felt a burst of magic from inside the castle. She warned the others and they ran towards one of the castle towers. When they were standing next to Twilight, the pieces of the elements, which Nightmare Moon broke, began circling around them. Then a glow appeared above Twilight as the element of magic was summoned.

The pieces created special necklaces, or crowns, around the group of ponies. Pinkie, Rarity, Fluttershy, Applejack, and Rainbow got necklaces, while Twilight and Solar got crowns. Then a flash appeared on Solar's flank, her cutie mark, a galaxy surrounding a rainbow infinite symbol that had a hourglass in one side and a magic bubble in the other, had appeared. It also became part of her crown.

The ponies shot a rainbow beam at Nightmare Moon, and it circled around her like a tornado. Seconds later, the ponies got up off the floor. They all viewed their necklaces/crowns. Then Solar looked down at her flank and saw her brand new cutie mark. She suddenly felt like she could control the entire universe all at once.

"Indeed you do" said Princess Celestia. The sun began to rise, releasing Celestia. She congratulated the ponies for their victory, and Solar for finally obtaining her cutie mark. Celestia walked over to the blue alicorn that had just woken up. The alicorn was Princess Luna, Celestia's sister. All the other ponies were surprised that Luna was Celestia's sister.

Princess Luna apologized to Celestia for her jealousy and for trying to bring eternal night, and Celestia forgave her. The ponies walked back to Ponyville for Pinkie's celebration party. Celestia noticed Twilight and thought that she was finally ready to go back to Canterlot. But Twilight said that she finally understood friendship and had friends. Celestia then allowed Twilight and Solar to stay in Ponyville with Spike, as long as she sent her daily messages about what she learned about friendship.

Twilight thanked the Princess and her new friends and Solar gathered around her for a picture. Just before the picture was taken, Solar exclaimed "Wait, don't take the picture yet. SPIKE, come over here."

Spike came over and was gotten into the picture with Twilight, Solar, and their friends. Then Celestia and Luna had to leave to go back to Canterlot. Twilight and Spike left to go back to the library, but Solar thought that there wouldn't be enough room for all three of them. So she looked around Ponyville for a house for sale.

She eventually found one and used her bits to buy it. It was a two story house with two bathrooms, three bedrooms, a kitchen, dining room, and living room. Solar teleported her possessions from Canterlot and used them to make her new home more cozy.

By the time Solar was done, it was very late. So she brushed her teeth and went to bed.
