In The Beginning Part 1

The White Knight, young Celestia and baby Luna who was sleeping at the moment, have finally arrived to the Earth. Now, young Celestia was rather curious about what White Knight does around here on the Earth, she starts to ask him on what exactly does he do when he's around here on the grounds, and so he answers to her;

"Well, as you can see, I come down here to keep an eye on the place, making sure that everything stays in place and what not. Gotta make sure that the Earth stays in perfect harmony no? Otherwise somepony might try to upset that perfect harmony with something... well, bad."

After hearing her answer, she realized that this world runs on both ways. There's good, and then there's bad, however she doesn't see any bad things going on at the moment, and that's when White Knight steps in again and tells Celestia that there's so much good in this world that pretty soon, a hint of bad will soon disrupt that goodness and will become something of chaos, corruption and pure hatred. That's why White Knight and Black Knight try their hardest to make sure that everything in the Earth stays in it's place, anything that's out of order... must be captured and restricted from the world, by sending them into a place where they can't do any evil. However, there's a difference on how they protect the Earth, White Knight is all about protecting the Earth and all of it's inhabitants, normally he's in charge of watching over the Earth ponies, while Black Knight watches over the Pegasi and the Unicorns. But, White Knight is all about protecting them all the ponies, for he has a huge heart of gold, he's even thought of bringing the Earth ponies, the Pegasi and the Unicorns together so that they can live well with one another, however the Black Knight will not approve of it though.

He doesn't like the idea of having all the ponies coming together in one room, he thinks that no good can come from it and that it's chaotic and unethical for all three tribes to live together. That's why he built the "Great Divide," in order to keep the three tribes separated, and therefore something like that tends to bother the White Knight. He believes that the Black Knight is very strict and has all these strict rules that he expects everypony in the Earth to abide and for the White Knight to not interfere with those rules. But of course, White Knight will not stand down for this, he'll still listen to his gut and trust his instincts on what he does best, because he believes that this is the right way. And his way is to find something so powerful that can bring the three pony tribes together, and that... is friendship. And while White Knight believes in Friendship, the Black Knight believes in order and perfection, basically his life's work.

"Look, Celestia. I believe in your father, I do. And I've always trusted him with everything, but there's this big picture that he's just not seeing. I have to get him to see, but for some reason when it comes down to it, he turn me away. But other than that, the Black Knight is a good pony, I know that well in my heart."

Afterwards, White Knight quickly changed the subject and proceeded on with the objective, and as for Celestia, she still believes that the White Knight is going to check in on the Earth's low grounds, high grounds and the skies.

"So, master White Knight, how long does this preliminary check go on?"

Then the White Knight started to laugh uncontrollably; "Oh, Celestia my dear, do you still believe that we're going to check on the Earth?"

"Well, if were not... then what are we doing?" After she said that, she started to smile, just a little bit. After all, she was a little nervous of what White Knight is actually going to do.

"Well, if you must know..." Then, he starts to get closer to Celestia; "Keep this between us, okay? But we're actually gonna go get some extra set hooves, if you know what I mean."

After what she had just heard, she was puzzled about what the fact that White Knight is in search for help, then she says to him;

"I don't understand, you're the White Knight. You are the most legendary pony of all of Equestria."

"Well, I may be legendary, Celestia. But that doesn't mean I can't have any- wait. Did you say Equestria?"

Then, after White Knight said that, Celestia had began to blush. She was a little red, but only because the White Knight knew that Celestia had made a little fantasy world for herself, whenever she's having some free time to herself. In her dreams, young Celestia wishes to be a beautiful princess when she gets older and that she would have a kingdom and that the land that she would live in would become "Equestria." And now that her secret has been blown, she tries to deny him and come up with the most ridiculous excuse to cover it up.

"Equestria? What makes you think I said that, I never said such a word. And you can't prove-

"Awww, Are we living in our little worlds again, Celestia?"

She became even more embarrassed than before, but she couldn't come up with any other excuse to continue keeping it a secret. So she starts telling the White Knight about her little magical world, she tells him that one day she's going to grow up to become a princess and her sister would rule alongside her, she was ashamed anymore of having to tell all of this to the White Knight, because she believes that it could happen one day and that she'll do whatever it takes to make it happen.

"Is that so? Well, Princess Celestia, I believe that you will make a fine princess one day. You and Luna both, and that's no lie.

"You really think so?"

After she said that, the White Knight started to giggle a little bit, and then he started to laugh out loud and uncontrollably. And then, after he was done laughing, he replies Celestia's question;

"No, I don't think so..... I know so."

After he said "I don't think so" to Celestia, she was a little shattered at first, but then after he said "I know so," that shattered feeling turned into a warm and fussy feeling, a very passionate feeling. In other words, Celestia was happy to hear that the White Knight believes that Celestia and her sister Luna would become princesses one day, then after that Celestia and the White Knight gave each other hugs. It was a beautiful moment between a master and his student, and as for Luna... well, she was still sleeping during all that, but then she started to wake up and Celestia went over to her comfort her. The smile on Luna's face when she saw her big sister was speechless, it was an adorable moment indeed. And then, when White Knight walked over to the girls, he wanted to see the smile of Luna's up close and personal, then something else happened... when Luna looked at White Knight, she began to say her first word...

"Da- da- Daddy."

Everything got all awkward for White Knight, Luna had confused the White Knight for her father, even Celestia was surprised. But she does believe that Luna has a point, because she told the White Knight;

"You know, she's got a point. In wonderful moments like these, I wish that... you were our father."

After that, White Knight kept staring at the girls, he was a little sad and also, happy to hear what Celestia had said. He had dropped a single tear from his right eye, but he kept a smile on his face, as he always does. And then they all huddled together for one great hug. It was a happy moment for all of them, even Twilight was standing there watching them the whole time, having their beautiful moment together.

"Oh wow, this is just a touching moment. The White Knight must be a really nice guy, based on what I've seen so far." Said Twilight.

Then she started to tear up as well, and she also says that it's no wonder why Twilight has a wonderful teacher, she was who she is now and it was all because of him... the majestic White Knight.
