Inside the house, Ocean finds many rooms, some of them look very old. It would take forever to find his sister in this house.
"Sis!? Sis!? Comeon out! Just what the buck is happening here!?"
Ocean didn't receive any answer so he decided to go up the stairs. As he got to the third floor, he noticed a huge hallway, only leading to one big door. He felt like he'd get some answers there.
Once he reached the door, he stopped for a second, he was afraid of what answers might await him if he meets his sister there.
"Come in, Brother, I know you're there."
Ocean opened the door to find his sister sitting on a throne.
"Just tell me already what the buck is going on here! Why can you change your appearing? What happened that night? Just tell me what is going on, what was that thing inside me! I know you know something!" Ocean shouted at his sister.
"My dear brother, why is it that only I remember? Why can't you remember anything? I will tell you what happened. Our parents were the ones who received a certain fate. Their fillies were supposed to be gods. Once they reach a certain age, their powers will gradually increase and they don't age. These fillies are us. We were both possesed by a spirit. The spirits of the former gods. While I was supposed to be the sun, you were supposed to be the moon. Together we were supposed to create a new world. A world in which everypony can be happy. However the spirits inside you are the moon spirits and they are said to be evil, gruesome and filled with hatred. Only a strong will could prevent any harm to the ponies around you. You remember that night, don't you? That night when you killed mother?"
"I don't know what happened that night. It's so fuzzy to me. I would never do such thing. It can't be real!"
"It was real. I saw it with my very own eyes. But don't worry, we couldn't have prevented it. Your will was not strong enough simply because we were all alone all this time. While I was the lucky one getting all the positive spirits, you had to endure unimaginable pain caused by these monsters. That's why I decided to lift that curse from you. As you noticed, my previous form was dark, that happened because of the spirits rampaging inside of me. If it wouldn't have been you who met me, I most likely would've killed you. They kept telling me "Kill him" but I refused and tried to run with my remaining willpower. But you just couldn't stop following me causing you to come here. To tell you the truth, it is too late now for you to leave. Soon, I will split myself into two. One being creating the sun, one being creating the moon. Once that happens my dark side will try to kill you while my good side you can see now will most likely try to save you."
"But why? I just don't understand! Why does it have to be us? What will happen once you split? What will happen to you?"
"I will be trapped in two different bodies, my good side will be watching over my dark side. However if those two collide in a battle, this whole world will be destroyed. One cannot live without another. I think it's time. I will split now and once that happens I'll pray for your safety. Goodbye, Brother."
"Just wait a second! What did you do to me? Why can't I remember anything? I don't know my own name, I don't know your name, I just don't know anything!"
"As for that, Brother, we will meet again. Once we meet you should have found the answers to that."
Ocean looked at her sister who seemed in pain. She started to shine in a bright light. Suddenly, something dark came out of her fur. Once it materialized he noticed it was the filly he met on the street who then started to attack him.
Right before the dark pony reached Ocean, his sister's horn started to light up, her mane coloring up in different colors. A barrier appeared around him and he heard a familiar voice.
"Dear Brother, I will send you to a time in which I am about to lose control, make sure you will stop me, I believe in you. Once you stand in front of me, you have to remember everything. If you don't, you won't have any effect on me and you will not be able save this world. Take care."
"Hey Ocean, wake up!"
"Huh? Where am I?" Ocean opened his eyes, looking up at the ceiling.
"So, how'd it go? Any success?" Twilight asked.
"I've learned quite a lot actually." Ocean answered.
"Have you regained your memories then?"
"Not quite but I know what I have to do now."
"What is it then?"
"I have to remember everything."
"Isn't that what we were trying to do already?" Twilight looked confused.
"Exactly, however we approached it the wrong way. Could you tell me if you have any books about how Equestria was made?"
"I don't really know what you are looking for there, but okay, I'll look around for it a bit. I'll tell you once I find it."
"By the way, Twilight. What was that book about you left at the hospital?"
"You know, I just wanted to make sure you'll be smart enough to be worth investigating." She giggled as she went off to look for a book.
