A/N: Prologue is set 16 years before Season 1 of My Little Pony: Friendship is magic. Luna was never banished though Nightmare Moon still exists but is a completely separate pony.

Luna's POV

I had just risen the moon to begin the night. At the time, I despised raising it, as I thought my subjects feared me, for they would hide in their homes at night. I often wondered what my purpose was in life.

But one night, everything changed.

That night, I had done my normal routine of raising the moon, when I noticed it had begun to rain and the wind started to pick up. Looking up at the sky, I spotted an unusually bright star breaking through the clouds and falling toward Canterlot Castle, or more specifically, my balcony. I dove through the door leading into my bedroom in an attempt to dodge the falling star. As if on cue, it changed course by turning right before it hit the tower, and when I got back up to see where it had gone, its path led straight toward my sister's garden. Upon impact, the star left a strange bird-shaped crater in the garden. Curious as to what could cause such a crater to appear, I flew down to it. Upon closer inspection, I saw a pegasus colt, with a white coat and blonde mane, lying in the middle of the crater. Using my horn, I conjured a levitation spell to pick up the colt and examine him. To my surprise, he was still alive. The colt opened his eyes, revealing two blue irises.I carried him back up to my room, and decided to rest until morning to ask my sister, Celestia, whether or not to keep him. I placed the foal on my bed next to me, seeing as I didn't have anywhere else to put him.

-The Next Morning-

I woke up around five to lower the moon so Celestia could raise the sun, and I noticed that the foal I found the night before was not in the bed. Worriedly, I scanned the room for him, but to no avail.

Where in Equestria is he? I thought when I began to hear giggling. Looking around the room again, I spotted him hiding on the roof of my bed. Smiling, I began to lower the moon as I had intended to do when I woke up.

"You're quite the troublemaker, aren't you," I said. "Then again, a lot of pegasi foals are rambunctious."

Out of the corner of my eye, I saw that the sky was getting brighter.

"Looks like Celestia's up. I think it's about time we introduced the two of you, don't you?"

I asked. The colt simply nodded, and much to my surprise, flew down, landed right next to me, and attempted to walk, which he apparently had difficulty doing as he fell onto his stomach. Chuckling to myself, I levitated him, placed him on my back, and walked out of my room. Seeing as Celestia's bedroom door was closed, I decided to head to the throne room, as she normally left her bedroom door open during the day. Upon entering the throne room, I saw that my sister was chatting with Shining Armor, a new recruit to the royal guard.

"So, you are saying that the garden was burned?"

"Yes, ma'am, and it had an impression of a bird."

"Now, what could have done tha- Ah, good morning, sister," she called out to me in her normal friendly manner. "Don't you know it's rude to eavesdrop?" She chuckled.

"I wasn't eavesdropping. I was merely waiting for you two to finish your conversation, Tia," I replied. "I have someone I'd like you to meet."

The colt flew off my back and turned to look at my sister, and to both our surprises, began to cower in fear at the sight of her.

"I'm not going to hurt you, I promise." Celestia smiled at the colt and turned to me. "Where did you find him?"

"I wanted to talk to you about that, in private."

"I'll take my leave," Shining Armor saluted us and left us.

"Last night, while I was, I saw a falling star land in the middle of the garden. I went to investigate the crater, and well...he was in the center." I recalled the previous night's events.

Celestia's eyes widened. "What?"

"I'm just as confused as you are," I replied.

"What should we do with him?"

"What do you mean?" I questioned her, unsure of what she meant.

"Should we adopt him? I mean, he's obviously here for a reason," Celestia reasoned. "We have more than enough space."

I contemplated this. It was true that we had more than enough space, so that wouldn't be a problem, but still…

"Are you sure? I mean, I'd be more than happy to adopt him, but I don't want to disturb anypony because I want a child."

"If that's what you truly want, I don't think anypony would mind. Now all that's left is to name him. Since you're the one who found him, I think it's only right that you name him."

Looking at the colt for a moment, I came to a conclusion about a name.

"I think I'll name him...Sun Light."
