As Celestia searched the crystal library, she could not help but wonder what secrets could still be hiding from Sombra's 'evil demon' moment. She pulled out a small spell book, revealing the tiny, grey button, obviously hidden by King Sombra. The curiosity got the better of her, so Celestia slowly pressed down on the circle. A large, dusty archway appeared in the wall, leading to the king's secret reading room. The former princess stepped inside staring at the many, many books stashed in the ginormous room. The books were all very appealing, but Celestia chose one off the top of the first shelf. Once again, a button was revealed. "A hideout inside a hideout? Genius!" Celestia chose a book off the newly revealed shelf. It did not have a title, which would have been extremely suspicious to a normal pony, but the alicorn didn't even notice. She flipped open the large book, taking a quick glance at it's components. "This is his journal..." She said, confused. "I wonder... NO! I shouldn't. I CAN'T!.... can I?" The princess could not fight the urge, so she sat down and began to read, starting with the third entry.
Another normal day here in the empire. Well, almost. It's been three days since my last entry, and I've seen some things that I really wish I hadn't known about. There seems to be something trying to attack the empire, and I think it wants me as it's first victim. I can't help but feel like there's more to this place that I'm somehow missing. It's crazy, I know, but really. Ever since I came here, everything's just been so... strange. I'm not normally one to be afraid of the dark, but I keep seeing these strange shapes hiding in the dark of night. Everyday they get clearer, as if they're trying to tell me something. Some ponies might say I'm going insane, but I think this all has something to do with my magic. I'm the only unicorn in my ENTIRE family! That has to mean something, right? I don't know. I'm going to look further into this. Who knows? Maybe it's my destiny! Speaking of destiny, it's day ten of the hunt, and I still haven't figured out what my cutie mark means. What could be so special about three crystals and a star? I'll keep looking, and write any information I find in this diary journal.
"This doesn't seem so bad. Why did he try to hide this?" She kept reading. As the day went on, Celestia had almost finished half of the journal. She heard mumbling from outside the secret room. Luckily, she was able to hide the hideout before anypony noticed.
"That's strange. The sun should be setting right about now."
The sun should be setting... It was at that moment Celestia realized what she had done. Luna was not capable of setting the sun on her own.
