No one's POV:

Of the many equipment in this world, metias are held in high regards by everyone. Unbeknownst to most, they were tools created by the Witch of Greed, Echidna. From the conversation mirror to the legendary meteor staff, each possess a great power.

Perhaps the only objects in this world that could rival their power in terms of extraordinary abilities are the Ten Swords of Power.

The Dragon Sword Reid, created by the first sword saint and possibly created alongside Volcanica, the Divine Dragon. Its current wielder, Reinhard van Astrea, remains the strongest individual that currently exists. The Sword was passed down by the Astrea family from one generation of Sword Saints to the next, and has stayed there ever since.

Cecilus Segmunt, the 1st Ranking of the Nine Divine Generals of the Sacred Vollachian Empire, holds another two of the ten. The Fiend Sword Murasame, and the Dream Sword Masayume. Although the swords are not his complete source of power, it's part of what makes the young man a powerful entity enough to match Reinhard.

The Yang Sword Vollachia lies hidden in the hands of an individual, waiting for their user to present them to the world. It chose their master, and even now, the princess is pondering about it.

The Life Sword Zeam, was collected by an eccentric noble by the name of Count Reedback. It currently lies in the storage of the noble, waiting to be discovered.

The Cursed Sword, emitting ominous auras, was sealed under the Witch of Envy's tomb, after an unknown individual moved it from its original place.

The Love Sword, hidden away in one of the corners of Kararagi, where only those true about love can approach it and make it their own to successfully draw its power.

The Blight Sword, whose powers killed various people, is sealed in the place where ironically, with the most diseases. The last Great Mabeast, The Black Snake, took it as one of its own as it placed it in its contamination zone, standing in the core of the dreaded area.

Now, lying underneath the Witch's Graveyard, an entity sat dormant in the hidden room that only the Witch of Greed is aware of. Beside it resides their own properties: The Shadow Sword, a special weapon that they have made it their own; and the Spirit Sword, the weapon of one of its former contractors. Both were stuck into the ground, unable to be pulled until it was the right moment.

And that moment was approaching.

The two swords let out a faint light as it roused the spirit from its sleep, and yawned as it smiled.

Her new master is coming. And she would be sure to see her friend as well.

For the first time in centuries, the Great Spirit of Yin, Bayanga, opened her eyes.

Y/N's POV

As we returned to the Arlam Village, the villagers got off and immediately searched the houses. To their surprise, no one was in any of them and they informed Petra and the other kids, who were extremely worried.

"So Ram and the other villagers hasn't returned from the Sanctuary yet?" Subaru asked, and I nodded in response.

"Well, I suppose Roswaal would know why they're still there." I told him, and he turned to Emilia to confirm something.

"Emilia-tan, do you know where the Sanctuary is?" Subaru asked her, and she shook her head in confusion.

"Eh? Subaru, I thought you knew where it was." Emilia asked, and Subaru looked equally shocked.

"Um, if it helps, I know where it is on the map, but I don't know how to get there." I responded, and Subaru sighed. "Well, I guess let's go back to the mansion first."

We then took a little journey back to Roswaal's mansion with Subaru and Emilia aboard Otto's carriage, while I rode on Fulgenta's back. Midway into the journey, I spotted Otto getting shut out of Emilia and Subaru's conversation as he suppressed a sigh.

"It's not easy being a third wheel, eh, Otto?" I teased him a little seeing how the nervous merchant would react.

"Ah? No, no... why are you so mean as well, Y/N-san..."

I silently laughed as Fulgenta chuckled a little as well. Within minutes, we arrived at the mansion, where it seemed abandoned for months. We knocked on the door, and an unfamiliar voice came through the door.

"Please wait a second, I'm opening the doors right now." The doors parted and revealed a blonde demi-human, who smiled and revealed her sparkly teeth.

"Ah, hello, Frederica-" Emilia began, but Subaru suddenly interrupted her.

"Those TEETH are scary!"

Timeskippu*

Emilia smacked Subaru on the head after that, and he pouted silently as Frederica entered. She poured us some tea, and bowed as she introduced herself.

"My name is Frederica Baumann. I was employed here in the past."

"Now that you mention it, I do remember that there was a maid employed here in the past..." Subaru said as he scratched his head, but can't seem to remember the exact details.

"I merely took my leave due to personal reasons. When I returned here at Ram's request, I found the mansion empty." Frederica stated. "Fortunately, I saw a letter in the master's room that was filled with a summary of what happened. Also, the kitchen and garden were in a desolate state when I returned."

"That's a pretty serious reason!" Subaru said, imagining how pissed Ram would be if she saw.

The latter went on to talk about Rem, and Subaru still had a tiny heartache on his mind as his teeth clenched a bit too hard as he explained who Rem was. Frederica confirmed that she also thinks that Rem is probably Ram's younger sister. However, Emilia was still confused at where everyone went.

"I believe that the only ones who the master trusts enough to entrust this knowledge are Ram and the great spirit of the forbidden library." Frederica said, and Subaru's eyes widened as he knew what to do.

Timeskippu*

I saw Subaru fly out of a door as he slammed into Otto, who was coming out of the former 'bathroom door'. I approached Subaru as he had a worried look on his face, and I sat down beside him as he looked at me with lost eyes after Otto got up from under him.

"Y/N... Beatrice was not in a great mood today, huh? She seemed like she was going to cry again..."

"Well, why do think she was going to cry?" I asked, trying to get him thinking more than he did in the original timeline.

"She did get sad after muttering a name. I think it was Juice or something."

"It's Geuse. And who shares that name that also recently died?"

"Huh? Died? What do you mean-" Subaru suddenly stopped talking as he managed to slowly fit the pieces together, and came to a conclusion. "You don't mean... Betelgeuse, the Sin Archbishop of Sloth?"

"Ya, I do mean him. He was a spirit, after all. He could've lived for a long time, despite being on of the odder ones. And he also used to be a very good person until he went insane." I said.

"Is this your future ability acting up again?" I nodded, and he sighed. "Well, tell me about it, how did he go insane exactly? Because whenever I think of that dude, I can't but help to feel he was always like that."

"It has to do with the second part Beatrice talked about. The Witch Factors."

"Oh yeah. What exactly are witch factors? Beatrice even asked me why did I kill Sloth if I didn't know what a Witch Factor was."

"Well, in short, it's what allows people to use an authority. You know how Betelgeuse can use the Unseen Hands? Those things' power stem from the witch factor. All the archbishops have one. Betelgeuse had a personality shift and went insane because his body wasn't compatible with it. If you aren't compatible, you go insane. Thankfully, Betelgeuse still had part of sanity attached, or else you would have something like a weaker version of the Witch of Envy from 400 years ago."

"Well... that is a lot to take in." Subaru said as I waited for him to process, and he suddenly remembered another important part of the talk. "Oh yeah, what happens to the Witch Factor of the host when they die? Do they disappear?"

"Of course not. If that happened, Betelgeuse wouldn't even have the Witch Factor in the first place. I don't know how those things are created, but I do know that the Sanctuary holds the answer." I responded, and he got up as I did as well.

"Well, let's go ask Frederica how to get there." Subaru said as we walked back towards the room.

Timeskippu*

I kept thinking of that conversation, even now. I rode on Fulgenta's back as we ventured into the Lost Forest of Clemaldy, where the supposed Sanctuary was. Otto was on the cart guiding Patrasche with his Divine Protection. Subaru and Emilia were in the carriage discussing things. Everything was peaceful.

At least it was supposed to be for a little longer.

Subaru suddenly screamed inside the cart, and I pulled on Fulgenta's reins to bring me closer to the carriage just as I saw the bright light of the pyroxene crystal engulf both Subaru and myself, and we were standing in the middle of a clearing.

"Um, Y/N, where are we?" Subaru said as I regarded our surroundings, and I saw an elf girl with pink hair standing behind us, with no particular expression. It was one of the clones of Ryuzu Meyer.

The clone started to run away from us, and Subaru got a little impatient. "Hey, wait up!" He yelled as he ran after the clone, and I followed suit. After a while, the clone disappeared from our sight as I saw the structure of the Graveyard, looming before us.

"Y/N, are we in the Sanctuary yet?" Subaru asked he regarded at the temple, and took some steps towards it.

"Well, I would probably say that we're somewhere on the outskirts, but I'm not sure..."

Subaru continued to go into the Graveyard, and I lit a tiny ball of fire just to help us see in the darkness as we advanced further into the Graveyard. However, before we can reach the end, a voice rang out as it made me and Subaru both freeze in our tracks.

"So that is the root of your desire?"

Subaru slumped forward as I stepped back in surprise, and tried to locate the voice of the Witch of Greed. However, no signs of her eagerness to meet two people at the same time showed. Well, that both sucks and does not suck at the same time. I suppose I could explore this place while Subaru's having his conversation with Echidna.

The rest of the way inside was dark, and I sensed more and more vines inside the Graveyard, but I continued on as I supplied myself with air. Just as I was about to give up and go back, a piece clicked under my foot as I recognized the cliche moment.

The floor opened up beneath me.

WHYYYYYY?

I screamed as I fell into the hole, immediately activating Suitoru as I gained the flight powers of the White Whale. Through the faintness of my light emitting from the magic circle, I flew downwards as I saw a pedestal with two swords embedded into it, as if their owner chose this area as their final resting place.

I don't remember Echidna's tomb having a secret room... so what is in here?

However, as I lighted Goa and began to move forwards, shadows bound me as I turned around, surprised as I tried to retaliate against whoever that tried to tie me up, an unusually cute face gave me a devilish smile as the small entity floated in the air.

"If you could go into this place, you must be master's successor, right?" The floating entity that resembled a succubus asked as I looked at it in confusion.

"Master's... successor?"

"EH? Has Cahya not told you about me? That selfish, egoistic, so-called best friend of mine. Was I not even worth a mention to my new master?" The succubus pouted as I suddenly remembered from something Cahya said when I first met her. A friend that she mentioned to be on the same level as her.

"Ah! So you're that Great Spirit that Cahya talked about before! I was always looking forward to meeting you!" I said, trying to lighten her mood a bit.

"So she did mention me!" The little succubus quickly repositioned herself as she bowed down to me.

"Welcome, Frakine-chan's successor. My name is Bayanga, the current Great Spirit of Yin." She said as she lifted her head and pointed towards the two swords embedded in stone. "Complete the trial I prepared for thee, and I shall pledge my loyalty to you as well."

Authority(ies):

Authority of Deceit (Commonly known as Authority of Elements):

-Vacuum Trigger: An innate ability stored within the tesseract-shaped Deceit Witch Factor, allowing the user to spring themselves from unconsciousness when the mana fluctuations around them changes drastically, as a built-in self-defence mechanism of the body.

-Critical Overload: A mysterious ability that protects the user of the Deceit Witch Factor, causing them to unlock their true potential while their actions are coordinated by ?, helping them avoid certain death. This ability only triggers when the user is about to die and has a 15 minute cooldown.

Then, the substance explodes from the inside to spread parts of itself into the opponent's body, replacing their atoms with the substance itself.

-Pure Truth: Y/N's knowledge of the future. Although he claims that he can only know up to a certain amount, it is only a cover-up to avoid suspicion.

-Veritas Oneiro Chunyu: The 'Truth Dream Injection'. A sub-ability of Pure Truth that allows the user to show others fragments of Pure Truth to get a better understanding of a situation or past. This ability cannot show the future.
