This chapter was proof-read by my favorite little racecarghost, racecarghost. Enjoy this chapter of explanations.

It had been hours since they had written to the princess and there was still no response. Twilight tapped her hoof on the desk and watched the sunrise nonchalantly, thinking of what Celestia was doing at the moment. Rainbow herself was about to leave when she glanced past the unicorn. The vampire scowled at the light in the sky and kicked a book, underestimating her powers. The book flew through a wall and into Twilight's room, hitting Spike in the stomach and sending him into a wall. The cyan mare smiled, guilty, and looked at Twilight, who was far from amused at her recent property damage. The mare rolled her eyes, retrieved the book and her assistant, who was knocked senseless by the paper projectile.

"Way to go, Rainbow." Spike grumbled, rubbing his temple. "You almost took my head off."

Rainbow just gave an apologetic grin and shrugged. "I guess I don't know my own strength yet."

Seamus laughed and fell on his back. "Sure, you just kill a thousands of years old vampire that has tons of dark magic at his disposal and you 'Don't know your own strength'?"

Rainbow gave him an annoyed look. "Ex me' on the pirevam'e"

"What? You should be proud."

The mare looked at the clock and sighed. "But I'm not... that's just it."

Twilight interrupted them, seeing the time. "Seamus, where are you staying today?"

The alicorn gave an indifferent shrug. The unicorn looked at the rapidly rising sun and then to Rainbow Dash.

"Rainbow... don't you have to go home about now?"

"Why? I've only been here for a-" She saw the sun creeping up over the horizon and almost screamed. "Oh no! I can't go out there! You guys have no idea how bad it hurts to go outside."

The mare jumped up and landed on the top of a bookcase, hissing like an irate bobcat at the sunlight creeping across the floor. Twilight rolled her eyes and drew her curtains shut with an experienced flick of magic. The cyan mare still looked at the window like it would explode open and fry her at any moment. It took her a few minutes to muster the courage and get down; even then she kept well away from any sort of glass panel. Twilight rolled her eyes again and said.

"Sea, you can go to Rarity's. The girls are there."

"But I'd really like to stay he-"

"Seamus. Go."

"Twilight, no."

Twilight balked, she hadn't expected him to deny her command. "What? Seamus, I have things to do and I have to get started trying to study Rainbow Dash. I can't have you here messing around."

"Twilight, this is a little more important, no offense, Rainbow."

"None taken, kid. What is it?"

"I think I know why Luna suddenly started to act all crazy. I had a book, it contained a lot of dark magic and if she got hold of it then I don't think that she would be able to resist it. After all, Jakben didn't."

He began to pace circles on the floor, his wings clenched to his sides so tightly that they could see the muscle underneath. He had an eye tic acting up and he couldn't stay still for even a moment. Twilight interrupted his pacing by stepping in front of him, blocking his path.

"Sea, what is so bad about a book? It's not like it will hurt anypony?"

"But it will!" He yelled. "That book is the reason that when Luna killed Jakben, he came back. That book taught him everything he knew about magic, and he wasn't even a unicorn. That book is not just a book, it's a real, living, breathing monster that grew its own consciousness."

Twilight looked at him dumbly then burst out laughing. "Sure, a book can just become alive and have a mind of its own. You've been reading too much yourself."

He leapt up and grabbed her shoulders, shaking her. "Listen to me! It is made of unicorn horn and a pony's skin! Every page is written in dragon's blood and it has some of the most vile, disgusting magic ever written! It talks to you, tells you things, tempts you with magical powers reserved for gods. I know, I tried to read it. It's held the magic in it for so long that the spells have woven themselves into something alive, a sort of hive mind created by magic. It's evil. That is all I can say to describe it. Just pure evil.

"Well then why aren't you evil and killing everypony?"

"Because I stopped. I found no more reason to learn from it and I closed it. It offered me power I didn't want, so I just shut it. Luna wouldn't close it. She's jealous of her sister; she would use the book to get more power than Celestia."

"But what purpose would it serve to torture you?" Twilight interrupted his lecture.

"I was getting to that. From what I've figured out, and from what I've read, the book feeds on negative emotions. Due to that, it would use Luna as a source of misery, all the while Luna was securing my obedience and fealty to her. Do you follow?"

Twilight nodded. "Just one more question. How did she get the book?"

"When you brought me to the castle after... you know. You brought my saddlebag. It had the book in it, Luna must have gotten it and it corrupted her, simple."

The entire room stopped and looked at him for a moment. It was a lot to take in, and quite frankly it sounded ridiculous. But it did explain some things. Like how Jakben had been able to cast magic when he wasn't a unicorn. And how he had come back to life after being eviscerated and burned. But one thing weighed on Seamus' mind. One little problem that he couldn't understand.

"Rainbow, how did you kill Jakben? I and Luna tried and we both failed. How did you do it?"

The cyan mare smiled, flashing her long fangs. "Well, when I left, he wasn't dead. I tore off his wings and threw him down a pit he had in his dungeon. He said to me, well, he kind of bragged. "This pit is bottomless. If I were to throw anything down there, they would starve to death before they ever hit the bottom". I just kinda put two and two together, waited until he had his back turned, then BAMM! I tore off his wings and threw him down. Try your fancy magic down there! Ya stupid feck!"

Seamus was impressed. So the only way to kill a vampire was to starve them. Fairly simple, easy, and didn't involve too much effort.

"So what now? We know why Luna went crazy, how exactly Jakben died, and now we know how to kill vampires should we ever need to. But where do we go from here?"

This left the room silent. Nopony had thought of that. What now? Continue life as normal? Move to Canterlot that way psycho Luna didn't track them down and kill them? As if to answer their questions, a scroll from the sun princess appeared in front of Twilight, landing on the floor with a rustle. The unicorn lifted it to eye level, cleared her throat, and began to read.

'I haven't been able to confront my sister. She is nowhere to be found. I've searched her caves, the castle, the crystal chambers and even the dungeons. She is nowhere. I cannot locate her and neither can the guards. I will keep you posted, but I cannot guarantee that we find her anytime soon.

~ Your faithful mentor,

Princess Celestia'

Twilight sighed and closed the scroll. "Well, I guess we all saw that coming."

Rainbow wanted to kick another book, but she decided putting an another hole in the wall wasn't worth it. This sucked, that hag of a mare had sawed off the poor kids horn and now she couldn't even make her pay for it because she had no bucking clue where the coward was. Woe betide the princess the next time the vampire saw her; she was going to beat her skull in, rip her horn off and shove it where the sun never shined until she ripped it open.
