Supreme Monarch

{Notice: Monarch Authority recognized.}

{Activation Process complete.}

{Welcome to the Boundless Void Library Lord Tyler Fall Darknar. I am Uriel, your magic assistant, how may I serve you?} 

"Huh?"

For a second there, Tyler couldn't comprehend what he had heard. Unlike the genderless and ethereal voice he had been hearing thus far, this one was clear and concise. A melodious female voice that sounded almost heavenly, originating from the library itself as it spoke in a reverent tone.

'What the hell is this?'

His mind raced to figure out what was going on and what the hell he had heard. The voice had been too clear for him to say he had imagined it so what's going on here. He hadn't even been able to think for long when the situation suddenly changed for the worse.

{Notice: Unidentified presence detected. Activating security measures.}

"Wait what?"

Before Tyler could comprehend what was said, the library suddenly went dark as a beam of light was directed at him. He frowned deeply and prepared to take defensive action even though Universal barrier was always passively active around him.

However, the beam of white light wasn't directly aimed at him and it caused him no damage but before he could wonder what was going on. He heard a loud shriek of immerse pain from below him.

Indeed, the streak of light had been aimed at his shadow, and due to the excitement of returning to the magic library after so long, Tyler had completely forgotten there was someone that was constantly hiding in his shadow.

He panicked for a bit as Zelda's shadow hide skill was forcibly disabled and her figure was revealed as she rolled on the ground screaming in absolute agony. 

This was an undead creature. A being whose entire existence rejected even death itself and thus was immune to all negative status effects such as pain. Yet such a being that was by no means weak, was being forced to feel pain by the Library.

"Wait Stop! What the hell are you doing!"

{An hidden unidentified undead creature was detected and thus, adequate and immediate actions were deemed necessary. Should I proceed in eliminating this creature?}

"No! Just cut it out. She's just my bodyguard!"

At his order, the beam of light that directly forced the sensation of pain into Zelda's core disappeared without a trace and the library returned to its previous well-lit state.

{Connection with Lord Tyler has been recognized. As a non-living creature, permission to remain with master has been granted. Core damage will now be repaired. Do you want this creatures core to be enhanced in the process?}

"First you almost kill her and now you want to enhance her core. Well fine, as long as she is fine afterward."

{Understood, the process will take 24 hours. Master is free to proceed further without worry.}

Tyler rushed over to Zelda's side to check up on her and she was out cold. His face that had been twisted in clear agony was now relieved as she slept. An undead could not sleep so this was just a state similar to that as her core was slowly being fixed and enhanced. It didn't seem like she would feel any more pain from the process.

With her like this, there was no way for him to put her in his shadow so he picked her up and took her to the side where he laid her on the floor before considering what the library (Uriel) had said. It seems no one else was allowed inside this library except him, but after this, Zelda would be allowed in due to her state as undead but he doubted if any more non-living creatures would be given the same leeway.

'Still, what the hell is going on here.'

Tyler then stood back up and turned to face the library. Observing his surroundings there didn't seem to be anything different in it so where the hell was that voice coming from.

"Hey, Libray! What exactly are you?"

{Incorrect assessment. I am not the essence of the Boundless Void Library.}

"You're not?"

{Correct.}

"So what are you?"

{I am Uriel, an artificial soul created from thousands of soul fragments and the essence of the fallen angel Uriel. I am now part of the Void Library's core and my entire existence is to serve you. You can also think of me as the library's manager or your assistant.}

"An artificial soul? Such a thing was possible?"

Tyler's question was rhetorical and as such, it was met which silence as Uriel judged he did not require an answer. Her intelligence was very impressive.

"Tell me, who was it that created you?"

{I was originally created by the Monarch and implanted into the Void library's core. However, I had only been activated for the first time recently due to the evolution of the magic artifact— Spatial Infinity. Therefore, this is my first time speaking with master.}

"The evolution? So you really are the ethereal voice I heard back in the cave. How the hell did you manage that and how did you affect my soul if you're bound to this place?"

"I was created to be of service to master and such, my soul had been linked to the artifact of the king, Monarch Ring and I should've been activated upon that item's activation but master hadn't activated it and as such, I was only awakened by request of the living properties of the artifact, Spacial Infinity.}

"Monarch Ring? So the item I took simply to gain access to the throne room and considered useless had such a hidden effect? I see. So why didn't you respond when I tried talking to you then."

{That was only a limited activation and communication is not possible with the artifact. I was only able to speak by accessing the living properties of the artifact, Spatial Infinity. Without that, no forms of communication would've been shared.}

'So I would've suffered that gruesome pain without any idea what was going on. Why does it feel like this thing only knows how to dish out pain.'

{Notice: Due to the uniqueness of the Monarch and the Acquisition of the living properties, further Analysis has been made and proper communication would be possible with the activation of the skill; Wisdom of Uriel, granting master the ability to access information from the Void Library at any given time. Includes a plethora of other skills and abilities to aid master.}

"And what makes you think I'm your master?"

{Lord Tyler Fall Darknar, caries the demon king's seed and had therefore been permanently registered as my master. My existence had been bound to you.}

"A seed?"

That word didn't seem to register long in Tyler's mind as he immediately shifted his focus from that to the so-called Void Librarian.

An artificial soul created from the remnants of thousands of souls most likely from the demon king's victims as well as a fallen angel's essence just to manage the library as its manager. Tyler could only stand in silence as he slowly processed the information.

According to Uriel, the Monarch ring he had ignored because it felt like it would be more trouble than it's worth was the reason he had gotten Spatial Dominance and could've activated Uriel sooner if he had activated it as it was a bound item that could not be used by anyone it wasn't bound to.

Apparently, the late demon king had created her to counter the massive drawback of the magic library that was apparently named the Boundless Void Library or simply the Void Library.

"So Uriel?"

{Yes, master.}

"Where exactly is this library located?"

{The Boundless Void Library is not located in a specific coordinate and randomly drifts through the void between all dimensions as well as traveling between dimensions occasionally to protect itself from powerful foreign entities that seek its power.}

'So it really wasn't bound to this dimension as I suspected, but this is even crazier than I thought. For a library of this absurd size to be able to move constantly across dimensions, a massive power source is required. So what is powering this place? Isn't this the same as the castle? I still haven't located the power source for that.'

"Is the constant shift in location why I can't stay here for too long?"

{Negative, connection with master's castle is unstable. Advice: Learn Advance magic runes to fix the connection. May also learn God Tier skill: Monarch of Concealment, to strengthen the connection.}

"So it all still boils down to magic runes eh... whatever then. I should probably get started before my time here runs out shouldn't I?"

Saying that Tyler turned his head around left and right, trying to figure out the direction the books on magic runes were located in the vast and seemingly endless bookshelves. Just looking at the massive library was now starting to annoy him until he realized there was now a supposed librarian so he asked for directions instead.

"Hey Uriel, where are the books on magic runes located?"

{Understood, sending master there immediately.}

Before Tyler could even consider what she had said, his field of view changed and he appeared in between a familiar section of the library where several books on basic, intermediate, and advanced runes were located.

"This is?"

{The Void Library's abilities. Does master require assistance choosing the most optimum book to start with?}

Tyler was silent for a while as the shock ran through him. Ignoring the fact that he now understands how his subordinates felt when he teleported them around without warning. He had planned to use spatial teleportation to move quicker through the library as well but had changed his mind as he wasn't sure if it would affect the library's stability and lock him out.

However, it turns out the library could do that all along and all he had needed to do was put on a stupid ring. Such wasted opportunities. While he would like to know what other abilities the library had, he decided not to think about that right now so he could focus on his current priorities.

"No thanks, I know what I'm looking for."

Declining her offer, he walked over to one of the shelves and picked the first book from the shelves that contained intermediate runes, level 2. 

His current progress was level 1 and he needed all three levels to learn advanced runes. Picking the book he wanted, Tyler was just about to move over to the Conner of the room to sit on the floor as usual so he could focus, when he suddenly stopped as a white exquisite desk and chair had suddenly appeared there. 

Tyler froze, his mind still processing the possibilities of what had just happened as he slowly opened his mouth to ask the dreadful question.

"Did-did you just create matter?"

{Negative, I simply moved the items from a section of the Library for master's convenience. }

"Oh, how considerate."

He sighed in relief at that response. It would be quite terrifying if a Library this powerful also had the creation ability. It was best he did not think of the ramifications of such a thing as he decided to just focus on his studies. He had a lot he wanted to do in the library after all.

Tyler then collected several more books from the shelves and stacked them on the desk so he wouldn't need to move around needlessly and proceeded to the chair and took a seat as he began his studies.

As he flipped through the pages of the first book. His mind steadily went blank and only the details of the information he was reading was left as the speed at which he was reading through book after book increased dramatically to the point that he would be considered a blur to any onlookers as he occasionally got up and replace the stack of books on his desk almost every 10 minutes.
