It has been about...a week...since that mission that Abyss had, along with Ravel and Ganyu. And needless to say, the mission had been a success for him and the other 2 girls that are with him.

According to his client, they were able to repel the enemies long enough for the village to have been able to find and create some new mining tunnels, and they discovered more ores down there. So thanks to the missions that Abyss and the others had done, they are able to save the village, allowing it to thrive a little more longer. And Abyss, thanks to this, was given a lot of currency, which allowed Abyss to move to the final stage of his plan. And thanks to the item that Lucida S. Serif had given to him, he is able to move to the final stage. And after he did all of that...he than was able to make a healing type of liquid. The liquid is the healing magic that he had been able to drain a little bit from each of the magical items, and combined, it will be enough for Abyss to use it in order to try and heal his brother from the wounds that he had received. He just needs to make sure that it is in a container that will not break and will not release the lid, even if he were to fall. And thankfully, Ravel was able to create something such as this, but this is only due to the fact that she had to infuse the magic within the bottle, in order to make it more durable, and if it were to break...than her magic will be force from return to her, and because of this, Abyss has to be careful with what he does, and how much of a fall that he will take.

With Ganyu...when it involves between Abyss and Ganyu...Abyss notices that Ganyu is being...odd...around him. She would often blush in his presence, and will speak in a rather nervous, hesitant tone to him, and he does not know why she is acting like that. He assumed that he did something wrong, but having a perfect memory of what he does, and how he watches himself, he realized that he did nothing wrong, and what she is doing is simply out of nowhere. He assumes it is due to timber fact that Ganyu is developing a crush on him, but that can't be right, due to the fact that Ganyu is like, thousands of years older than him. So why wound Ganyu, a lady that is so incredibly old compared to Abyss, would want to be with him? That would make no sense whatsoever. Besides, Abyss and Ganyu, they are just friends. It is not like they know each other that well to begin with anyway, so it would also be another reason for that to not make sense at all. Because of this, Abyss still tries to act normal around her, tries to treat her like the usual type, meaning as a friend, but Ganyu would still stutter, and sometimes, Abyss would even feel like Ganyu is trying to touch his hand, but he does not seem to notice this strange thing happening.

However...as Abyss and Ganyu are still friends...something happened. Yesterday...he notices and heard from a bunch of people and the councilors that Ganyu and the other members of the council, who she works with...they are apparently involved in something that involves the Adepti. He does not know why...but he notices that they are taking what seems to be much more harsher and more ruthless measures against them. He does not know why this is the case, but he knows that this sort of thing is not good, and that it will lead to something bad, maybe even another war, if this is not resolved peacefully. Because of this, he thinks that he will need to leave this place and never come back. But he is torn of having to leave Ganyu behind, due to the fact that she is his new friend, but he knows that Papyrus will not stay having to wait. Because of this, he made a choice to try and go back to his brother. While he knows how painful it is, to try and leave behind a friend, and having to leave her in a potentially bad situation...he just hopes that Ganyu would simply move on and look past him, so that he does not get in the way of her job.

So...with one last look at Ganyu...Abyss sighed...as he than took out a piece of paper and a pen...before he than began to think of what to write down, for Ganyu to notice. As he does think of that, Alta Fayon spoke out to Abyss, as she 'looks' at the paper in his hand.

"What are you doing, Sans?"

Abyss looks up at Atla, as he than spoke out.

"I'm...writing one lady goodbye letter to Ganyu. If she decides to come by, and she notices that I am here...than I need her to understand as to why I need to leave. Of course, I cannot tell her about where I am going...or it will be something that will not be good, but I need her to hopefully, move on from me, and to her herself not be limited if her job, because of the bond that I share with her. So...it is kind that I get to say goodbye to her, before I leave her behind, even if I am leaving this world forever."

Atla Fayon looks at Abyss in the face, as Abyss has a rather sad sign coming from his mouth. He clearly does not want to do this, but he needs to be back to his brother As Soon As Possible, and hopefully, heal him from the wounds that he had gained. Atla nodded her head, as she sat down next to Abyss, and leaned her head against his own. Abyss, taking a deep breath, took out his own, and he began the write down the last goodbye letter, and in hopes that Ganyu would simply just leave him behind, and forget about him. He does not want to be the one that limits her job as secretary.

"Ganyu,

I know that this might seem to be sudden to you...but I am not inside of the 2 shops anymore. It is because I am done. I got what I needed, and I need to leave. You are probably wondering as to why I had decided to take the healing items...it is because it is a family matter for me. You see...I never mentioned this to you...but I have a brother that needs my help, and I cannot leave him. He has extremely severe injured, due to an incident that has happened to him about 2-3 years ago, and I cannot keep him waiting for me for too long, for I need to rush in order to try and help him get better with what I have gained throughout the years. I need to go back to where I came from, so that I may help him. I also want to let you know that...I am very grateful...for all the times you had to be with me, for all the times they were spoke and how kind you act to me. But I beg you to please...do not follow me. This is my problem...and mine alone. And besides...I noticed and heard that you and the councilors are taking a lot of harsh measures against something, and I am afraid of what it will result in. I need to get back to my brother...to make sure that he is able to feel better. So please...do not find me, for I do not want to get in the way of what is extremely important to you, and how it will effect your home entirely. Be safe, and good luck in what you must do."

Abyss than began to tap his pen on his chin, as he thought of anymore words to say, but he found and thought of nothing that he can add to the note that he had just made right now. So...he decides that what he has made, is enough for Ganyu to read. So, after a little bit, he stands up, and tapes it to the front door, as he and Atla than walked up to Ravel Phenex, as she is waiting for them. Abyss and Atla continue to walk to Ravel, at the mercenary shop that Abyss owns, for a about 10 minutes, before they then had reached their destination.

As they walked up to where they needed to be, they see Ravel Phenex, putting a sign that says, 'Selling.' Ravel than turns to both Atla and Abyss, as she than spoke out.

"Oh, Atla, Abyss, you're both here. You'd steady to go?"

Abyss nodded his head.

"I did. And I got the concoction ready."

He said, as he holds the bottle in his hand, as Ravel nodded, with Atla holding her hand on Abyss.

"Then...let's go. Let's find a place to teleport without interruptions."

Abyss nodded, as Ravel and Atla than began to walk away, and began to try and find a spot for Abyss to use his teleportation. But unbeknownst to the group...there is someone watching them. Looking at the 3 teens from the shadows, is an entity, and it is the same one that had watched Abyss' fight with Nightmare. The entity continues to watch, as he saw Abyss and his group leave, before his eyes narrowed, and he then teleported fast.

Timeskip...

It is nighttime now, and it is shown that Abyss and his girlfriends are walking through what appears to be a dark forest of some kind, as Ravel used her hellfire to act as a type of lamp for them to see inside of the dark area that they are inside of. Abyss and Ravel look around very cautiously, due to the fact that they have no idea what is within those woods, and the fact that there are a lot of hostile creatures that are likely somewhere around here, just ready to kill them at any moments notice. Abyss, looking around, however, he notices that there are no creatures in their vicinity, that are attempting to go and attack them.

Abyss looks at Ravel, as he spoke out.

"We're almost there. Just another mike to go, and we will begin, and hopefully, without any sort of interruptions."

Ravel nodded her head, as she spoke out.

"You're right. But I have a weird feeling that there is something else that is about to go on...and it does not seem like a very happy thing to have."

Abyss nodded his head, as he than took out the Undertale Multiverse Book...and he is on a page that describes an entity. It is not a Sans, nor a papyrus...in fact...it is one of the many unique entities. It is a being that is known as Sol. Apparently...Sol is said to be the God of the Unnameables, a group of incredibly powerful entities that feed on the empty spaces of reality and feed in thoughts of others, as well as being true masters of manipulation. But Sol is the first entity to become an Unnameable, and is the most powerful entity of all time, or at least, it is said to be so. Apparently, his father, Gaster, despite being in a low-tier universe, had managed to see him during an experiment, but it is a small glipse at a fraction of Sol's appearance, and not the full appearance, otherwise it would have been a disaster for his father, as seeing much more of his physical body would be enough to drive even his father insane, which would have been bad. It is a good thing that he did not go nuts. Abyss has read Sol in his books, and he saw the abilities that he has listed, at least, the few that he knows of, and Sol's abilities are absolutely insane. They are just so bizarre and ridiculous, than even Abyss wonders if they are even abilities at all. Well, whatever it is, he does not want to see Sol in person, due to how disastrous it will be for Abyss to be here.

The only problem is that the page does not show Sol's picture, and maybe that is for the best, for he doesn't want to know what Sol looks like, due to how terrifying it might be for him. But there is some stuff that he has been able to know about Sol.

It is said that Sol continues to grow continuously, in that he is able to evolve and gain new powers continuously, like Abyss, except that his CELL Core is absolutely weak, compared to Sol, and he has no words to compare himself, other than the fact that Abyss himself would be stomped, with people such  as Error being able to last slightly longer, probably for a few seconds before they die effortlessly. In fact, Abyss even wonders just how many powers that he has, and how large he is now. Well...maybe he is larger than a whole group of Multiverses, maybe bigger than that. But whatever the case is, it is obvious that he should not be in his presence, unless he wants it risk his own sanity just to see him. Ravel and Atla have looked at that page, and even they look a little scared at the picture, claiming that they should not see this one. Luckily, the good thing is that they do not know of where he is, and it is perhaps a good thing.

Anyways, Abyss and the others are continuing to walk, as Atla than stopped...sensing something.

"Atla...what's wrong?"

Abyss said, as Atla spoke out.

"We aren't alone. Someone is following us."

Ravel than spoke out.

"Is it Ganyu?"

Atla shook her head no, as she than spoke out.

"No...it's not her. This presence...it is sickening."

Than...a voice spoke out from complete nowhere.

"AHHHHHH...SO YOU FINALLY NOTICED MY PRESENCE. IT IS IMPRESSIVE, EVEN THOUGH I DID NOT REVEAL MY MAGIC."

Than...footsteps were heard, coming from the woods, and the group stepped back a little bit, as they turned to see who it is. Abyss also stepped back, as he has no idea what it is that he is about to look at, only that it will not be a pleasant appearance to see. Abyss' eyes narrowed a little...but it than widened, as he looked in shock at the what he is seeing before his eyes.

Standing before the group, now in full appearance, thanks to the light of the moon reflecting the sun, is an entity, standing at the height of 8 feet, and is wearing clothing similar to Abyss' except that the coat is red, with a fluffy black hood, and yellow scarves, with 2 large arms at the lower part of the back, with hands ending in black claws, and on the palms of both the normal and large hands, are eyes, with teeth for eye lashes, and star-shaped irises. In fact, the black fluffy hood has eyes all over, but lack the teeth for the eyelashes. He has red skin, and his torso is revealed, but with a mouth that has a green tongue, sharp teeth, and a black eyeball with the star irises in the place of where the gem is supposed to be, and the slippers are red in color with an eye on the top part of the front slippers. The fingers, at least, the ones that are on the normal positions of the hands and arms, have long black claws, and his teeth are sharp and jagged, with a black tail similar to that of a devil, and has horns like a devil as well. His eyes on the face are the same as the eyes on the hood, in that they have irises. And the clothes themselves, they look as though they are a part of his body.

Abyss and the others are horrified at the sight that is before their very eyes, as they have never seen anything like this before, and Abyss does not know why...but he feels like he should no this entity...even though this is the first time that he has seen something such as this before. Than, the entity spoke to Abyss.

"IT IS FINALLY NICE TO MEET YOU IN PERSON...ABYSS."

This made Abyss step back a little bit, as he spoke out.

"Who...who are you?"

The entity smiled a little bit at Abyss, as he than spoke out.

"AHHHH...THAT'S RIGHT, WHERE ARE MY MANNERS? I AM SIMPLY KNOWN AS MES. IT IS A HONOR TO FINALLY MEET YOU."

Abyss stepped back a little bit more, as he than spoke out.

"Well...based on the way that you are speaking to me, you are clearly not a very friendly person. And besides, I have a feeling that you are not here just to simply greet me and say hello. You want me, right?"

Mes smiled, as he spoke out.

"YOU ARE MORE INSIGHTFUL THAN I EXPECTED. YES, I DO WANT YOU. OR RATHER...SOMETHING THAT YOU HAVE WITHIN YOU. ESPECIALLY IN THAT FIGHT WITH THAT FOOLISH GUARDIAN OF NEGATIVITY."

This made Abyss' eyes widened, as Ravel spoke out.

"How do you know about that?"

Mes smiled, as he spoke out.

"I HAD OBSERVED THE BATTLE BEFORE MY MANY EYES, AND I HAD SEEN WHAT ABYSS IS CAPABLE OF, ESPECIALLY WITH HIS RED EYED FORM, AND HIS ABILITY TO CREATE NEW LIFE. IT IS SOMETHING THAT I WANT, AND I WILL GET IT."

Abyss took a step back, as he than spoke out.

I do not know why you want it...but I will not let you have it, Mes. For that power is mine, and mine alone."

Atla and Ravel than spoke out.

"If you want to get Abyss and his power...and we will fight with him against you."

Mes smiled a little wider, as he spoke out.

"I ACTUALLY EXPECTED THAT. IF YOU SO DESIRE TO FIGHT ME, TO STOP ME FROM GETTING WHAT I WANT...THAN WHY WASTE OUR BREATH, EVERYONE? LET US GET TO THE POINT."

Mes then stepped toward, but then, all of a sudden...he vanished from sight, shocking the group, before Abyss spoke out.

"WATCH OUT!!!"

Abyss and the 2 girls moved away, as a large fist tried to grab onto them, as Mes looks at Abyss, before he than points his middle and index finger, as he spoke out.

"RULER RAY."

Than, an aqua red laser appeared from the tips of his 2 fingers, and Abyss nearly got hit, only for him to teleport out of the way. Abyss looks up, and he saw the Ray extending up above and out of sight, but he has no idea what would have happened if he had gotten hit by the Ruler Ray, which he called it, but whatever it would have happened, it would have been a very bad moment for him, and that is simply to put it mildly. Mes looks at Abyss with a twisted grin on his face, his teeth not making it any better, as Ravel and Atla tried to fight against Mes, but Mes simply pushed them away, and even though, by the way it looks, it is nothing but a light push, it is still powerful enough to send them both flying into opposite directions by a mile away, and that is with an extremely tiny portion of his strength.

He than took a step toward, and the grass turned red and thorny, as it tried to trap and ensnare Abyss.

"MATTER CONVERSION."

The red thorns than began to track and try and attack Abyss to trap him, but Abyss rose himself up into the air, and tries to fire an Abyss Blaster at Mes, only for Mes to block it with just a finger, and that is simply from his hands in the normal human position. Mes than made the scarves turned into extras limbs with mouths and hands all over the place, as he than tries to attack grab Abyss.

"SELF-CONSUMPTION."

The scarves tried to grab at Abyss, but Abyss than used his own scarves to attack Mes', as he than spoke out.

"Mes...he is not taking this seriously. It's like I'm not even worth his time, and is simply holding back his power to entertain himself. Just what is this guy?'

Mes than raised his hand up, and suddnely, red bones with mouths and eyes all over it appeared, as he then fired it at Abyss, before Abyss than raised his hands up, and blocked the bone, but he still ducks, and the red bone crashes through the wall of bones that Abyss has made, and this is a wall that is at full power, and is using the CELL Bones at their fullest, deadliest extent. Even Error would have to use a lot of effort in his attacks, in order to break them, and Mes, did it without effort.

This made Abyss terrified, as Mes looks at Abyss with his eyes, before he than spoke out.

"GIVE UP, ABYSS...YOU CAN NEVER WIN AGAINST THE LIKES OF ME."

Abyss, however, maintains his composure, as he than spoke out.

"Never!! You maybe stronger than me, but I am not going to give up that easily! I will not let you take what I have!!!!"

Mes smiled a little bit more, as he than spoke out to Abyss.

"HOW NAIVE YOU ARE, ABYSS. YOU ARE DOING NOTHING MORE THAN FIGHT A LOSING BATTLE AGAINST THE LIKES OF ME. DO YOU HONESTLY THINK THAT YOU CAN KEEP UP AND FIGHT AGAINST SOMEONE SUCH AS I? HOW UTTERLY PATHETIC YOU ARE. YOU CANNOT WIN AGAINST ME. IF I WERE YOU, YOU SHOULD JUST GIVE UP, WHILE YOU STILL HAVE A CHANCE."

Abyss smirked, as he than looks at Mes in the eyes, before he than spoke out.

"That's the thing, Mes. I never taught myself how to give up, and when to quit. I taught myself to keep on going no matter the challenge."

Mes than shrugged with a sigh, as he than spoke out.

"SO BE IT. YOUR FUNERAL THEN. AND IT WILL BE A SHAME YOU'LL NEVER REUNITE WITH YOUR BROTHER, PAPYRUS."

Abyss was shocked. He didn't mention Papyrus at all on the fight against! How does he know?! Then, Mes raised his fingers, the index and middle, as a red sphere began to form in front of the both of them, and he than spoke out.

"RULER RAY."

He began to charge his attack, but then...a bunch of icy projectiles came out of complete nowhere and hits Mes, making him back up a little bit, and he than stopped at the attack that he is about to fire, as he made a sound.

"HMMMMM..."

Abyss looks, and he saw that someone is coming down, and he cannot believe who it is. It is none other than Ganyu, for real this time.

Abyss is absolutely stunned, as he cannot believe the fact that Ganyu had decided to come and find him. But why? Hasn't she seen the note that he had given and wrote out? If so, why did she still find him? Unless...she did not come to the shop, but instead...she simply heard all the noise...and she came rushing in to see what it is that's happening.

"Ganyu, what the-"

As Abyss spoke our, Mes spoke out to Ganyu.

"AHH...SO THE NEW FRIEND OF ABYSS HAS ARRIVED. I WAS WONDERING IF YOU WERE GOING TO SHOW UP TO ME SO THAT YOU CAN FIGHT AGAINST ME. SO WHY DON'T YOU ANSWER ME THIS QUESTION SO THAT I CAN UNDERSTAND, WHY IS IT THAT YOI HAVE DECIDED TO CONE AND CONFRONT ME INTO A BATTLE THAT YOU KNOW THAT YOU WILL NEVER BR ABLE TO WIN AGAINST?"

Ganyu says nothing, however, as she than looks at Mes, as he hands began to grab onto something she has.

Ganyu readies her bow to fire a charged ice arrow. But Mes does not seem to care. In fact, he seems unimpressed and amused by the fact thatshe is pulling out such a measly weapon before his very eyes and is clearly wondering how it is that she is going to fight off against him. He simply raised his arm up, and blocked the attack, without any sort of effort whatsoever, and he than simply fired a red bone at Ganyu, who then dodged the attack. But then, Mes than raised his hand up, and then, all of a sudden, before Abyss even realizes it, Mes had summoned a Blaster, and it is of the same shape as the Abyss Blaster that Abyss uses whenever he attacks. It is different, as it is colored red, and the fact that it has multiple eyes all over the place, and the fact in that the teeth is sharper and jagged. He then fired it, and it is an aqua red color, with the DNA Spiral inside of the blast, just like the one that Abyss has, and Ganyu, she used her dash ability to barely dodge the attack, before she than decides to use something else with her, which she had carried with her.

Ganyu held a sphere of magical ice in her hands, as she than began to use it to rain on top of Mes, on hoes to cause a lot of heavy damage and disorientate him. Ganyu than threw the sphere into the air and began the rain down ice on top of Mes, which hit him. But oddly, Mes is still fine, acting like the attack is never there. He is getting hit with ice and cryo attacks, and yet, here he is, still acting fine. Then, Ravel Phenex came, and charged at Mes, as she launched a bunch of Hellfire attacks at Mes, making him stumble forward a little bit, but he does not feel any sort of pain, and in fact, is merely acting because he feels like it. Then, Atla Fayon came out of complete nowhere, and attacked Mes, punching him in the face, and tries to kick him, only for Mes to try and use the teeth on his torso to bite her leg off. thankfully, Abyss swooped in just in time, and carries Atla backwards, as Mes than spoke out.

"IT APPEARS THAT THERE WILL BE FAR MORE PEOPLE WANTING TO PLAY WITH ME. NO MATTER, I SHALL TAKE YOU ALL TO A PLACE, WHERE IT SHALL BE YOUR LAST."

He then raised one of his large hands into the air, before he slammed it down on top of the ground...and a bright flash of red energy occurred and caused everyone to close their eyes. The shining continued for a few minutes, until it stopped...and when everyone opened their eyes...they looked around...and saw that they are now in a different dimension. The entire dimension looks red, but there are pieces and bits of other pocket dimensions, one of which is the Anti-Void, and Sans looks to see the Abyss Dimension also being present. His eyes widened in shock; he cannot believe what he is seeing. Then, Mes stepped forward, as he then spoke out.

"ARE YOU ALL READY TO CONTINUE WHERE WE LEFT OFF?"

Then, Abyss walked forward towards Mes, as he then spoke out.

"Hold on, how did you-you have a blaster that is of the same shape as mine, you manipulated your scarves the same way that I have done, and you even know of the dimension, the Abyss itself! How in hell do you even know of that, and why is it that you sound like you are familiar with me returning to Papyrus, even though we had just met?!"

This made Mes froze, as he then grinned wider.

"HMHMHMHMHMHMHMHMHMHMHMHMHMHM...HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA."

The way he laughed is unsettling, he sounds loud, and yet his voice was not raised, as he then spoke out.

"ABYSS...CELL...HAVE YOU NOT CAUGHT ON AS TO HOW I KNOW, SOME OF YOUR ATTACKS BEING MINE, AND HAVING KNOWLEDGE ON WHAT YOU KNOW OF?"

Abyss and the others feel a little bit unsettled, as Mes than spoke out to Abyss.

THE ANSWER...IS SIMPLE...BECAUSE THE TRUTH IS...

I...

AM...

YOU."
