Chapter 1 – Infinite Knowledge

A ray of light beamed into a large room through a stained glass window with the pictures of six ponies, one yellow, one pink, one white, one blue, one orange, and one purple. The beams landed on a purple alicorn causing her to slowly open her eyes from her deep sleep.

It had been a peaceful night for the mare, finally getting some sleep after her long hours of royal duties last night. She pulled herself out from under her lavish purple silk sheets and unsteadily stood on the marble floors below. She gave a quick yawn and a stretch of her wings before continuing towards the massive doors of her bedroom.

The first week had been quite an experience for the new princess. Her lot of royal duties were quite different from anything else that she had done before but she figured that she would get use to it, eventually. But now she had focus on what duties she had for today.

Reaching the massive double doors of her bedroom, the alicorn took a few deep breaths. You can do this, Twilight. You have been doing it for a week now. It will get easier as time goes on. Upon opening the doors with her magic, Twilight noticed a small wrapped gift lying just in front of her.

“I wonder what this is?” she asked herself. Picking up the small gift in her lavender aurora and bringing it to her face, she began to carefully studied it. The gift didn't seem like anything out of the ordinary, it was small, rectangular and wrapped in a dark blue wrapping paper. The only thing that confused Twilight was that there was no note saying who it was from or who it was for, but it being left in front of her sleeping quarters led her to believe that it was for her.

Turning around, Twilight quickly went back into her room and shut the massive double doors. Sitting down at her personal desk, she pushed aside a small mountain of books and scrolls just to make some room for the gift. Carefully unwrapping the small gift revealed a black book.

“Why doesn't this book have a name?” pondered Twilight as she began to study the outer cover. The cover felt old but also new at the same time, it also felt like no material that Twilight at felt before.

Twilight slowly opened up the book to its first page then quickly flicked back and forth through all the pages in the book.

“Why isn’t there any writing?” Twilight said in frustration while picking up the book in a forehoof and throwing it across her bedroom, “What sort of a gift is a book without writing?”

the book landed on the far bedroom floor a strange multi colored glow surrounded it and began turning through the pages. Stopping at a page near the middle the multi coloured glow vanished. “Ok? That was strange.” questioned Twilight as she began to nervously walk towards the book. Slowly Twilight placed a hoof onto the open pages.

“OW!” cried Twilight in pain and quickly removed her hoof from the page. What was left on the page was a red outline of her hoof which began to move and rearrange itself into one word.


The writing then continued to break apart and rearrange itself while a stunned Twilight watched with a wide open mouth.

Infinite Knowledge
Infinite Power

With the final words the witting slowly vanished without a trace.

“Wait! Come back!” shouted Twilight as she desperately tried to get the writing to return “What is ‘Hidden Library’?” Twilight was now obsessed with this ‘Hidden Library’ and the book knew it. Slowly the writing began to return.

Do you want to know about the Hidden Library?

“Yes” answered Twilight enthusiastically and clapping for forehooves.

The Hidden Library contains the knowledge of all reality, all of time; past, present and future.
Twilight was shocked, a library that contained the knowledge of everything and she wanted to find it. “How can I get to this library?”

I can show you but the road will be extremely dangerous

“I don’t care about the dangers!” snapped Twilight “I just want to know how to get to this library”

The book remained quiet for a few seconds before replying.

Very well.
Follow me

With that the book became silent once more. Its last line confused Twilight the most. How on Equestria do I follow a book? I mean a book can’t walk but maybe this book can. I mean it is able to understand what I am saying and even respond. Wait... am I going crazy? I have just had an entire conversation with a book! Is that even possible?

The book distracted Twilight before her thoughts could get out of control. All the writing began to pile together in the centre of the pages to form a red circle. Once the circle was fully formed, little droplets of red began rise up out of the page. These droplets sat still in front of Twilight’s face before they started to spin around in a large clockwise circle.

As the droplets got faster and faster, small thunderbolts began to arc of the spinning circle, hitting randomly around Twilights bedroom. Soon a small vortex was being formed in the middle, slowly expanding to the same size as the outer spinning droplets. There was a flash a blinding blue light when the circumference of the vortex met the droplets.

When Twilight finally opened her eyes she was speechless. Directly in front of her was a shimmering portal of blues, reds and purples all swirling around in a transfixing spiral. Twilight gulped, she had never seen such magic before.

“Well here goes nothing” said Twilight before nervously stepping into the swirling colours. As soon as she was completely immersed the portal closed behind her with a loud crack and a few strips of lightning across the floor.

Chapter 2 – The Realm of Change
To all non Warhammer 40k players that are reading this - I will put at the bottom of every chapter a little description/pic of the main Warhammer 40k things that are in each chapter so you people don't get confused with some of the things that I am mentioning. I hope that this helps you people.

”Tzeentch is not content to merely observe the fulfilment and disappointment brought by the passage of time. He has his own plans - schemes that are so complex and closely woven that they touch the lives of every living thing, whether they realise it or not. The chaos god’s masterly comprehension of time, history and intrigue allows his ploys to intertwine seamlessly, forming a web of causality that spans the stars”

-Codex: Chaos Daemons, 6th Edition

A nightmarish land greeted Twilight’s arrival. The sky was half on fire while the other half was a mix of every colour in existence and rivers of pure magic were weaving through all the sky. The ground was a desolate wasteland, littered with hundreds and thousands of individual crystals, each a different size, shape and colour from the last.

The geography never stood still for more than a few minutes, it was ever changing. Crystal mountains would move at their own accord, disappear entirely or appear out of nowhere. It was like the land was at a constant eternal war with itself.

The wind was as chaotic as the land was; it would change direction as constantly and randomly as the land itself. Sometimes it would just stop entirely or turn into a full force hurricane without a moments warning.

“What is this place?” wondered Twilight while gazing out onto the shifting land, “It’s like Discord but a thousand times worse!”

The black book floated to the front of Twilight’s face before opening to a random page to begin writing.

This is the realm of magic, nightmares and chaos. Each civilisation has a different name for this place but it is most commonly known as the Immaterium or the Warp. The Immaterium doesn’t exist within the real universe or any universes beyond. It exists just outside the universes in its own pocket of reality

Twilight took a moment to ponder on what the book had just wrote. There are other universes, worlds and civilizations other than Equestria. If I can find a way of reaching them, then there would be so much to learn about them, their way of life, their technology and so much more. This thought of knowledge of other worlds put a huge grin on Twilight’s face. Maybe this book can lead me to infinite knowledge.

“So where is this ‘Hidden Library’?” asked Twilight.


Twilight face hoofed at the answer, “Of course it is hidden. If it wasn’t hidden then why would it be called the ‘Hidden’ Library. Now can you please show me where it is?”

Look that way

Underneath the writing was an arrow pointing to the book’s top-left corner. Looking in that direction, Twilight spotted what looked to be like some sort of castle appear out of nothing in the far distance but it was far away for her to tell exactly what it was. “What is it?” she asked.

It is the fortress that holds the Hidden Library. We must be quick, for as it will vanish within hours

“Well I better get going then” Twilight said before starting to walk in the direction of the structure and keeping an eye on the surrounding landscape just in case that it would suddenly change around her.

It wasn’t long before Twilight began paying too much attention on the changing landscape around her and not much on what was in front of her hooves. She stepped on a loose roundish crystal that sent her crashing down on her flank. She slowly got off the ground and gave a quick gentle rub to her sore flank before inspecting the offending trip hazard.

The crystal was the size of her hoof and an almost rugged egg shape. It had a dull maroon colour to it and no shine whatsoever.

“Is something in there?” she asked herself before taking a closer look at the crystal.

Upon closer inspection Twilight could make out a figure of a bipedal creature. It was wearing green and cream coloured clothing which Twilight believed to be some sort of armour. The figure seemed to be kneeling on some invisible ground with both hands firmly placed on the sides on its head. It looked like the figure was screaming but Twilight couldn’t hear anything.

“Who is that? Why are they trapped in this crystal?” asked Twilight the book.

The crystal holds a soul of the damned, one of those who sold their soul for wealth and power. Upon death their souls are sent here to be trapped for an eternity. Upon being trapped in a crystal it is only a matter of time before the individual goes insane. Each crystal you can see holds a different soul and the larger the crystal, the more important the individual.

“Wait...WHAT?!” asked a stunned Twilight “Who in their right mind would sell their own soul just for wealth and power?”

In a universe that has been in an eternal war for that pass millenia, anyone would do anything just to survive. Now you must get going, the fortress will vanish in a couple of hours

With that said Twilight continued on her journey through the Immaterium with the book floating just behind her.

“Why aren’t I getting any closer to that structure?” asked Twilight while kicking one of the numerous crystals in front of her, “I have been walking for at least two hours now and it doesn’t look like it has moved any closer”

The ground beneath Twilight began the violently move. Before she could react a massive column of crystal shot up into the sky, with her desperately clinging to the top of it. She was screaming the whole time and badly wanted the column to stop moving.

Once the column finally stop its ascent, it took Twilight a few minutes for her to regain her breath and for her heart beat to stop racing. Looking out at the chaotic realm, Twilight had a clear view of the structure but it was still too far away for her to make out any of the details.

“I wonder if I could teleport that far?” she asked herself before she began to slowly charge up her horn.

Closing her eyes, Twilight put as much effort and concentration as she could muster into this one teleportation spell. As the charge building up in her horn grew larger and larger, small bolts of lightning began arcing out of the crystals in the ground and into her horn.

Twilight couldn’t take the strain of all the magic that was building up in her horn, she started to scream. She tried to stop the spell or release the magical build up early but something was stopping her, something that forced more and more magical energy into her body.

Twilight soon lost control over the teleportation spell, it was rapidly absorbing all the magical energy around her. The magical build up was getting so large that it started creating large cracks in Twilight’s horn.

Just as Twilight thought that her body would explode from all the magical energy, the teleportation spell finally released with a gigantic explosion. The magical detonation shattered the top half of the crystal column into millions of fragments while the lower half split into nine equally sized shards.

And Twilight was gone...

“This, Twilight Sparkle, can absorb more Warp Energy than any of my Lords of Change ever could” said a godly voice to himself “She will become useful asset in my Grand Schemes”

The chaos god his head to one of the many Lords of Change that were folking around him in His library. “Xi’nath’ix, retrieve this lost soul before she is lost to the warp for eternity. Make sure to place her within the labyrinth and bring back my book. She has more trials ahead before she will my eternal puppet of change.”

Lord of Change - The most powerful kind of Daemon of Tzeentch. They are highly skilled in magic and are the leaders of Tzeentch's armies.

The guy in the crystal - He is known as an Imperial Guardsman which is what an average human soldier is called in the 41st millennium.

Chapter 3 – The Crystal Labyrinth - Part 1: Living Crystals

”Tzeentch is the undisputed master of magic. Sorcery is one of the most potent of all agents of change, and those who use it are amongst the most ambitious and hungry for power. The use of magic is held as the ultimate expression of faith amongst Tzeentch’s followers, who have much to gain from his patronage. Thought it will like as not cost them their immortal souls for it, they will at least have boundless power to show for it”

- Codex: Chaos Daemons, 6th Edition

Where am I?

Why can't I see anything?

Why can’t I move?

I can’t feel anything restraining me.


My Head!

Why does it hurt so much?

The pain of emotions?

Love and Hate, Happiness and Sadness, Fear and Hope, Ambition and Despair.

Why can I feel them all?

I can’t think any more, my mind is burning up.

The pain...the pain of emotions!

+~Unknown Psychic Transmission Intercepted 784M40, Transmission Origins: Unknown~+

Twilight didn’t know where she had ended up after the overloaded teleportation spell. She couldn’t see, hear or smell anything. The only thing that she could feel was every emotion rushing through her head and it was starting to burn out her mind.

Twilight felt what seemed to be a large clawed hand grip around her body. The sudden feeling of something grabbing her seamed to block out all the the emotion rushing through her head. Twilight tried to resist her captor but found that she couldn’t move a muscle, even the limbs that were dangling freely refused to move. So she just let this creature take her to the unknown.

After what Twilight could guess to be five minutes, the creature layed her body on a cold hard surface. Finally regaining the ability to move, Twilight slowly and painfully opened her eyes. A large figure was looming over the purple alicorn but her vision was too blurry to fully make the creature out. Blinking her eyes a couple of times to remove the blurriness, Twilight finally had a clear look at the creature that was looming over and presumably saved her from where ever she was.

The creature was huge, at least three times the size of Celestia and look like some sought of hybrid between a bird and a human. Its dark blue skin and feathers were covered in a large white and light blue robe with golden edges.

Gripped in the claws of the creature’s right arm was a staff made of multi colored fire that extended to about the same height as the creature itself. At the top of the staff was a large opened book that constantly flipped back and forth through the pages.

The most striking feature, that Twilight couldn’t stop staring at, was its bird like head at the end of its long slender neck. Its beck was filled with razor sharp teeth that easily looked like they could rip through Twilight. Highly decorated gold plates covered the top and sides of its head and had a hole on each side for the eyes. Eyes that burned with red fury and that could burn into anyponies soul.

“Ummm... H-Hello” Twilight nervously said to this creature.

The creature didn’t respond, instead it turned its burning gaze away from Twilight and took a few steps back from her. The creature positioned itself into a take off stance before spreading two enormous wings made of Red, Blue and Purple feathers. Seconds later it took off, leaving the alicorn behind.

Twilight got back onto her hooves and looked around at where this creature had left her. She was in some sort of room without any roof, the walls and floor were both made of crystal. And there was no way out.

“What is this place?” Twilight asked out loud “I have never seen anything like it”

On the wall directly in front of Twilight writing began to appear as if someone invisible was chiseling it out.

Welcome, Twilight Sparkle, to The Crystal Labyrinth. Your task is to find you way to the labyrinth’s core but it will be harder than it seems, for the labyrinth is alive and will constantly try to stop you. Many have tried to find their way out of here only to be trapped for an eternity.

You must reach the centre if you wish to live and the use of magic is forbidden, you don’t want to repeat what happened with your teleportation spell do you? And next time I won't save you.

Just as Twilight finished reading, the writing reverted back into the smooth surface of the crystal wall. A piece of the wall to Twilight’s left slid down revealing a corridor.

“Well I better get going then” said Twilight to herself and she began to walk to the newly revealed path. “Wait... Couldn’t I just fly over the walls? The writing didn’t tell me that I couldn’t”

Stopping just in front of the exit, Twilight stretched both wings to remove some of the stiffness that had built up from not using them. Getting into a take off position, Twilight looked up at the half burning half multi coloured sky. With a powerful thrust of her wings she took off above the labyrinth.

Twilight halted at an altitude about one hundred meters above the Labyrinth. Twilight couldn’t believe to scale of the maze, it stretched further than the eye could see. On the horizon she could spot a large spire protruding out of the labyrinth.

“Well that must be the center” said Twilight but before she could set off, four crystal arms rocketed out from the Labyrinth below. Each arm grabbed a separate hoof and began to drag her back down. Twilight struggled against the four crystal arms but they had her too well.

Twilight’s struggling caused to the crystal arms to get angry. Instead to quickly bringing Twilight quickly they instead stopped and started to toss her around like a rag doll. Before the purple alicorn could throw up from being violently tossed around, the crystal arms pelted her straight back down towards the labyrinth.

Twilight tried to regain some control of her rapid spiraling descent but she was moving too fast. On the way down her wing collided with the top of a wall resulting in a loud snapping noise before she crashed into the hard crystal floor and becoming unconscious.
