Overlord: Abyssal Tale

by Seereni

Generic "what if another guild member instead of Ainz got stuck in the New World?". OC-centric, obviously enough, and rated M because this is, well, Overlord. Still, I plan to write a much more approachable OC than Ainz, so the NPCs are going to be taken aback by how open and genuine OC is as the one big difference from canon. PS: Demiurge's world comes crashing down.

Found this old story I wrote around 2017, I think (?), while looking through my drive.

And I decided to improve it a bit and post it.

Now obviously, if you only found this fic because you already followed me as an author, make no mistakes: my Danmachi fic "Kenshi: Grasp the Heavens" is still my main focus, so I doubt I will post this Overlord fic as regularly as Kenshi, at least until that fic is done.

But I thought maybe focusing on this for a while will help me as a writer, so here we are.

I did read the Overlord Light Novel, just as a side-note.

Three times, in fact. (because I like it a lot) -_-

Then again I'm not the kind of guy who is hardcore on miniscule details, so don't expect me to hold true to every little single thing.

Also, I don't play DnD.

I am aware of some Classes, what Feats are, Cantrips and all the other 'surface' things, but I don't play it myself.

So reviews that are helpful in case I write something that is absolutely horrendous both as far as the DnD system and the Overlord setting is concerned?

Highly appreciated.

Reviews that are childish and only make fun of the fact that I don't know much about the things I already stated I am not highly knowledgeable about?

Yeah no thanks.

Also, I rated this story M because: 1) it's Overlord, 2) it's Overlord, 3) I might insert some smutty scenes later on.

With a big emphasis on "might".

Writing stuff like that does not count among the things I am good at.

So yeah, anyway.

Here is my own Overlord fic, "Overlord: Abyssal Tale"

(damn that name is cringe)

'Reality is merely an illusion, albeit a very persistent one'

Though he could not remember by whom exactly this quote was, it nonetheless popped up in his mind as he watched the events unfold before him. It did, after all, fit the current situation rather well.

"Momonga-sama!"

The cry of the Succubus at the foot of the podium on which the Throne of Kings was located echoed throughout the large and spacious Throne Room. There was pain and hurt in her voice, emotions which should not have been possible for NPCs like her.

'...The hell is going on here?'

Arms crossed across his chest, he looked over to the side.

The six maids which made up the Pleiades Six Stars, as well as their leader Sebas Tian, looked likewise hurt as they watched the now empty throne with saddened eyes.

'...The hell...is going on here?'

Reasonable enough, he tried to open up his console, but the UI was nowhere to be found. Neither could he use chat or contact the administrators.

Everything was gone.

'If this is a joke, I ain't laughing you know…?'

Beneath his simple white mask, similar to one from Venice before the city sunk down under the water some long years ago he felt his lips tremble in what was an uneasy smile.

"Why...Why did you leave me...Momonga-sama…?"

'Jesus fucking Christ, if this were to be a play, Albedo would no doubt make the whole audience feel for her with her tears. They are so genuine, after all. Most importantly, why does her mouth move when she speaks? And also, crying is not a function in YGGDRASIL. Ahhh, this is giving me a headache…'

If there was any solace to be had for him, it was the fact he was still cloaked in his stealth which he activated prior to...this. Though he was just a small distance away from Albedo and the other NPCs none of them managed to pick up on his presence.

'Stealth skills for the win, I guess. Now...I can't use my UI, nor any other game functions. I've heard about something like this happening in anime from Peroroncino, but I hope I'm just sorely mistaken about that…'

Shaking his head once the man closed his eyes and tried to think of what had happened so far.

…

…

It was the last day of YGGDRASIL.

The servers were set to shut down at midnight.

He entered the game as always, being one of the few active players left of Nazarick besides the Guild Master himself, Momonga.

Then he checked up on his own NPCs before going out to kill some mobs for the last time.

Roughly around the last hour he went back to Nazarick and found Momonga there, as well as HeroHero. They chatted for a bit before HeroHero had to go back, too tired to stay until the end.

With only roughly twenty minutes left, he quickly left the game before logging back in to walk besides Momonga one last time to the Throne Room while keeping his Stealth active.

He would role-play as the Shadow until the very end, that is what he decided.

Arriving within the Throne Room, Momonga sat down on the World Item, Throne of Kings while he himself leaned on the closest pillar to the right.

The time was ticking away, soon the servers would shut down. Silence reigned between the two before Momonga had a look at Albedo's setting.

"...Uwah...A bitch?"

'Suffice to say, as expected of Tabula.' He replied with a message.

"...True enough."

Goofing around a bit, Momonga used his authority as the Guild Master to rewrite her setting from a bitch to 'she is deeply in love with Momonga.'

"Haaa...This is so stupid…"

'There are literally sixty seconds left before this game shuts down for good. Leave it, Momonga.'

"True enough...Hey...It was...a fun ride, wasn't it?"

'Yeah. No doubts.'

"Hehe, still sticking to written messages…? You really never let go of your character, up until the end."

'Well, role-playing was part of the original idea of this guild.'

"Hahaha, it was, wasn't it?...Hey. If there is gonna be a YGGDRASIL 2...let's play again." The Guild Master told him on a melancholic tone after he changed the setting of the Guardian Overseer.

'...Yeah. Let's.'

And then midnight came, the time when the servers were supposed to shut down and forcefully eject all players out of the game.

…

…

And yet, here he was.

Still within the game.

Still within Nazarick.

The throne Momonga sat upon was now empty and that was evidence enough for him to figure out that this situation was not a server-wide error.

For some reasons he was the only one still within the game.

'...I have a bad feeling about this. Please don't tell me this is the poison I drank a short while ago now at work…'

The massive doors leading to the Throne Room he was currently in opened and in walked a tall individual with pointed ears and wearing a stylish, red suit.

This was Demiurge, the Guardian of the 7th Floor and the appointed defensive leader.

'He's...walking all by himself. So it wasn't just the NPCs within the Throne Room?'

"...Sebas." The Archdevil addressed the Head Butler as he stopped a short distance away from the stairs leading to the podium, noticing Albedo's state as he stared at her for a long moment. "What happened here?"

"It is as I said in my [Message], Demiurge. Momonga-sama, the last remaining Supreme Being, has...left."

Contrary to his stoic and professional appearance, the Head Butler's voice was filled with sorrow and sadness as he spoke those words. The Pleiades behind him shared this feeling, the pain visible on their faces.

"...I see." The Archdevil nodded a moment later, a sigh escaping his lips as he pushed his glasses up with two fingers. "Then we have failed."

'The hell are they going on about?'

"It would...appear so." The butler nodded.

"We have proved unworthy and as such the Supreme Beings have left Nazarick and us, their creation, behind. The greatest blunder creations like us could commit came to be." The Archdevil went on as his head hung low. "However…" Demiurge raised his head and looked around the Throne Room, at the various flags spread across the majestic columns. "The Great Tomb of Nazarick is still here. At the very least, with the hope that some day the Supreme Beings will return to us, I shall stay here and protect the domain of the Supreme Beings."

"Indeed, that would be the one option left we have as their creation."

"Mhm. Sebas, contact the other Floor and Area Guardians and have them assemble here. Though that is my desire, there is no certainty the others would feel the same about staying here. Let us decide what each of our moves are going to be next, now that we are without a Master to serve."

Sebas nodded and moved his fingers to his temple, no doubt to send a [Message] to the others.

'Holy cow, I thought it was just Albedo and the others in the Throne Room experiencing a glitch of some sort, but...did the NPCs...gain free will? How the hell…is this even possible…?'

"…! What is this?!" Lost in thought as he was, he failed to notice Demiurge bringing up the console and looking through it before the Archdevil's finger froze upon it, his face twisting into shock. Then he turned to the others. "Change of plans!"

"What is it, Demiurge?" Sebas inquired.

"If what the console is showing me is correct, then there is one other Supreme Being still with us!"

"Is that the truth, Demiurge?!"

'Oh. Shit…'

"Yes, it appears that we have not yet been completely abandoned. There is one last Supreme Being remaining."

'I have a bad feeling about showing myself to these NPCs right now...Come on, Ring, don't let me down.' Realizing they were talking about him, the man clenched his fist and focused on the red ring on his finger, trying to make use of it's effect.

"Which of the forty-one Supreme Being are you talking about, Demiurge?"

'Focus. My Stealth is still active, so no doubt this Ring of Ainz Ooal Gown must also work. Just gotta focus and imagine. Focus, and imagine…'

"It appears that from the ranks of the forty-one Supreme Beings, Eidolon-sama is still present."

Just as those words reached his ears, Eidolon managed to make use of his item and within the blink of an eye, he changed location and instead of the Throne Room, he was now standing at the entrance of the guild.

However, instead of the scenery of the swamps that surrounded it in Helheim all Eidolon saw before him were tall, snow-capped mountains.

"...Okay what the actual past, present and future fuck is going on here?"

A short while later…

Having heard Demiurge's summon the Floor and Area Guardians all made their way to the Throne Hall, where the Archdevil was waiting for them.

The news of Momonga's departure had shook them, and on those who had human-like faces and expression, the gravity of the news was indeed visible.

Aura and Mare, the twin Floor Guardians of the 6th Floor, walked forward slowly while holding hands, using their other half as the support they were both in dire need of.

Cocytus himself lacked a face which could express emotions, but Demiurge could tell that the warrior was deeply hurt by the departure of their last Master. Ashamed even, if Demiurge knew his fellow Guardian half as well as he believed he did.

Shalltear did not lose the aristocratic elegance of her stride, however she kept her face hidden behind the dark umbrella she carried with her.

The same applied to the Area Guardians as well.

No one within Nazarick failed to understand the meaning of the last Supreme Being leaving them, nor did any of them not feel ashamed at this turn of events.

"I see everyone is here." The Archdevil and acting leader of all of Nazarick voiced as he looked from left to right, making sure everyone he had summoned was present. "Then, though I already informed you of the saddening news in my [Message], but I shall repeat myself: Momonga-sama, the last remaining Supreme Being, has left us."

His words echoed for a moment longer within the large spacious room, the overall mood of the group of NPCs growing even more sombre.

"However…" Demiurge's voice drew the attention to himself once again. "Upon further investigation, it seems that is not the case."

"Demiurge. Do. You. Mean. To. Say. That. Momonga. Sama. Is. Still. With. Us?" The large insectoid Guardian asked as a mist of frigid cold escaped his mandibles.

"No. But as I inspected the console of the Great Tomb of Nazarick, I noticed that one name is still acknowledged as being present by the Tomb itself: Eidolon-sama."

Silence reigned over the Throne Room for the next couple of moments as the NPCs allowed the new information to sink in.

They were not without Master.

However, one most concerning matter remained.

"Demiurge, may I ask you something?" The True Vampire inquired after a moment of thought. In return the Archdevil simply nodded. For some reason, Shalltear had no doubts he knew what her question would be. "I am aware of this name, and that it is to be held in the same regards as the other forty, but...I don't seem to know anything about Eidolon-sama?"

A quick look around and Shalltear realized that she was not alone in her lack of knowledge: the other Floor and Area Guardians seemed to share her burden.

"...Indeed, I find myself unable to muster any sort of knowledge on our remaining Master, as well." Demiurge voiced. "Though this is a matter we should get to the bottom of with utmost urgency, it does not have priority over finding Eidolon-sama and making sure of his safe return to Nazarick."

The flame of hope lit up in the NPCs eyes again as they finally managed to grasp onto something again, on the knowledge that not all of the Supreme Beings had left them for good. One was still out there, one they could pledge their loyalty to.

"With that in mind, I would like to ask for the cooperation of everyone gathered here in tracking down Eidolon-sama and bringing him back to Nazarick." Not sooner had these words left Demiurge's mouth that the various NPCs gathered in the Throne Room gave a deep nod, ready to set out and find their lost Master. "Mhm, good. I have already tried contacting Eidolon-sama via [Message], but it got cut off. Going by this we can imply that our last Master founds himself in a perilous situation. We must make haste. I shall now explain the group compositions and how we shall move forward in our search-"

"Demiurge-sama." The Archdevil's speech got interrupted by the Area Guardian of the 8th Floor, Aureole Omega. "The scouts you have sent out just reported back. They wish to be allowed entry into Nazarick."

With a nod from her superior Aureole opened a [Gate] leading directly into the Throne Room, from which four high-level Demons, all serving under Demiurge himself, stepped forward.

"Report."

"Demiurge-sama, we bring concerning news. The outside area surrounding the Great Tomb of Nazarick is no longer the familiar swamps of Helheim."

"...What do you mean?" Demiurge inquired.

"...It's a mountainous area, my Lord. We are surrounded by tall, snow-capped mountains on a radius of at least three kilometres."

The revelation came as a surprise to both Demiurge and the others, but the Archdevil quickly collected himself. "Then the reason for Momonga-sama's disappearance, as well as Eidolon-sama's lack of response at my [Message] might be linked to this sudden translocation of the Great Tomb of Nazarick...Indeed, we cannot waste any more time. While the lack of information on our surroundings will no doubt prove difficult in our search, we can not allow it to stop us."

"I agree, but there is one last thing…" The female twin voiced as her eyes trailed from Demiurge to the Throne of Kings and the Succubus that hung onto the armrest of said Throne. "What happened...to Albedo?"

The Archdevil looked over his shoulder at the form of the kneeling Succubus. She was supposed to be their leader, appointed to her role by the Supreme Beings themselves. Yet in this time of crisis, she could not fulfil her role.

Demiurge could not bring himself to tell his fellow Guardians that their Overseer had cried herself to sleep while hanging onto the armrest.

"...Momonga-sama's departure has greatly affected her. I shall take over her duties temporarily." As he was already the appointed defensive leader of Nazarick as well as the co-leader of the Floor Guardians, no one had any quarrels with him taking over Albedo's duties if the woman herself did not protest. "Now, we have wasted enough time. Our last Master is out there somewhere, and we need to find him. Prepare for the full mobilization of Nazarick's forces."

'Oh wow, real snow is awesome.' Eidolon though to himself as he rolled up some snow from the ground then grabbed it within his palms, giving it a round shape before placing the palm-sized ball of snow atop the other two he had piled up.

Contrary to what a certain Archdevil was worrying about, Eidolon was having the time of his life creating a small snowman out of the snow that stretched for as far as the eye could see.

After all something like snow was no longer a natural occurrence in the real world, and though Eidolon had seen in through virtual reality before, feeling it with his own hands was a whole different experience.

'Then again, I don't feel the coldness on my hands, nor the numbing sensation the documentaries told about.' He raised his hands and stared at his ashen plum skin and naturally black fingernails. 'Jesus...The level of bodily awareness in YGGDRASIL was nothing to scoff at, but...this is real, right? The snow, the sky and even my avatar's body...It's all...real, isn't it…?'

His thoughts drifted to the NPCs back in Nazarick, specifically Albedo and her cries he had bore witness to, but quickly shook the thought out of his head. 'Not to mention…' Eidolon looked down, at his legs. 'I got legs again. Real legs I can feel and stand with…Holy shit…'

All he did since leaving Nazarick was slowly walk around while staring at the mountains all around him, but now…

Eidolon put his gloves back on and took a deep breath.

Then he exhaled.

And the next moment, he sprinted off.

Suffice to say, the fact that everything around him became a blur did shock him but his legs kept on running before he decided to stop, main leg up front. After sliding on the snow for a long moment he came to a halt.

'I'm fast. And not like "I'm first in line at the cafeteria" fast, but fast.' Looking over his shoulder he tried to spot the snowman he had previous put together, but he could no longer see it. 'A hundred meters…? No, it certainly felt like more. But my sprint didn't last longer than two or three seconds...Holy crap baskets…'

The game became reality.

That is the only conclusion he could come up with.

But at the same time, he did not recognize the area he was in. Eidolon was certain this area was not part of any of the nine worlds of YGGDRASIL. Thanks to his skills it was not false to say that from among the forty-one Players of Nazarick, he had engaged the most in solo-scouting across the game and was thus familiar with all the nine worlds.

He could say with confidence the mountain range around him was not part of the game.

'So then, all that remains is to think that Nazarick got translocated to a different world? Reality? I remember reading about this being a popular genre of anime but...to think it could actually happen...Jesus fucking Christ…'

He had tried to deny the fact but now that he took the moment to ponder on it, Eidolon realized there was little point in denying it.

The game's UI was no longer present on his screen.

He could not contact the GMs.

He felt his own body as if it was real.

Not to mention the NPCs…

'...Don't think about the NPCs. That is too scary right now.'

With a deep nod to himself, Eidolon turned to look at the weapons on his person. Five katana, one at his left hip, two at his right hip and two on his back. Five Aspects, he called them. All were Divine Class.

How was this possible?

Grinding.

And a lot of real money he threw at the game.

In YGGDRASIL he picked job classes that allowed him the use of swords, and though he only had two hands and thus could not make use of all five of his swords simultaneously, that had not been the idea to begin with.

He wasn't as min-maxed as certain Players of course, but nonetheless he did not simply choose classes just for role-playing, either.

He had wanted to be of use to his guild and as such much thought had been put into his built.

Taking in a quick breath, Eidolon bend his knees and wrapped his fingers around the sword at his left hip. 'Attacking would usually cancel my [Abyssal Cloak] I have active on me right now immediately, but then again I am not targeting anyone at the moment. Should be fine, I guess?'

Not wasting any more time he drew his sword and performed a horizontal strike.

To say he was surprised when the snow covering the area around him got blasted away by the simple motion of his sword strike would have been an understatement.

'...Was that wind pressure? It was wind pressure, right? Holy crap, I blasted the snow away with wind pressure…'

Staring at the blade in his hand, Eidolon took a moment to process what had just happened. He already had a suspicion from a moment ago when he sprinted who knows how many hundred of meters in a couple of seconds, but…

'I'm strong. And not as in, I'm a Level 100 Player. I'm...physically strong? Did my stats somehow affect this body's traits? If so, to what degree? I mean, I'm not someone who maxed out my Physical Attack or Physical Defense, but they are certain among my highest Stats…Hmm'

Sheathing his sword once again, Eidolon noticed that he still saw the world as if a blue filter had been applied to everything. His [Abyssal Cloak] was still active, which meant that the fact he did not attack anything despite drawing his sword did not cancel the Skill. He was glad to find this out, as he would otherwise stand out like a sore thumb.

His Divine Class leather armour was navy blue after all, and in a place like the snowy mountains he would no doubt be visible from a mile away.

'So anyway, I'm strong right? I mean, I blasted the snow around me away just from drawing my sword. That's gotta mean something. But then…?'

Shaking away his hesitation Eidolon walked to his left until he came close to a cliff. Looking down he could see a ledge some fifty meters or so below his current location.

'Am I really doing this? I am, right? Right? I must be more crazy than I thought…' He hesitated of course, like any normal person would. But at the same time, he also found himself rather calm despite what he was about to do next.

Then taking in a deep breath, he jumped off the cliff.

Within seconds he had landed down on the ledge and remained motionless for a couple of moments.

'...That...didn't hurt? Huh, neat.' Pushing himself back to his feet Eidolon took a moment to check his body, his legs and arms. Yet despite the long fall, he could not feel a single bone broken in his body. 'Oh wow. I certainly felt the gravity pulling me down and the impact of my fall, but I'm unharmed? Is it the defense granted to me by my armour, or simply the fact that my Level 100 Status granted me superhuman sturdiness? Well...if I actually became my Avatar, then I ain't human no more…'

It was incredible.

He was calm, mentally at least, but all those revelations did excite him. Granted, somewhere deep in his subconscious Eidolon was scared.

Scared of what all this meant, scared of how all of this came to be.

Why did it all become real on the day the servers were meant to shut down?

Where even was he?

And what did it even mean, if he was trapped within his own Avatar?

'This is more than what a person like me is meant to deal with. But...I'm kinda excited. Wanderlust, was that the word? Whatever it was, I certainly feel the desire to find out more. Things like excitement are rare in our world, after all…'

He had tested out his physical abilities, but one matter remained.

His Skills.

If this world was anything like YGGDRASIL, then no doubt monsters and the likes would be a very real thing. And unless he could count on his Skills, Eidolon saw little chance of himself surviving if he ever came across things like Bosses or the likes.

'Using any other Skill while [Abyssal Cloak] is active will nullify my stealth, but...I'm in the middle of nowhere, and Nazarick is a distance away as well...This is an appropriate risk, right?'

"...[Fly]." He uttered the word, as his race had the natural ability to fly. Within the blink of an eye he began to hover above the ground, no longer feeling his feet touching the solid stone beneath him. "Holy shit this is neat! And wow, my voice is all deep now...Huh."

Somehow he had the knowledge of how to control his flight already imprinted in his brain and with a single thought, he was able to make himself fly higher into the air. Higher and higher, until he stood above the tallest peak.

And then he saw the world spread out as far as his eyes could see.

Forests at the foot of the mountain, lakes in the far away distances, even what looked like the walls of a city?

"...This is...amazing…"

A whole world was out there, before his eyes.

A world most beautiful and unlike anything his actual world was like.

There was no pollution, no sky-high buildings, no smog and the subsequent dark-grey clouds covering the skies.

It looked like a vibrant world, like how YGGDRASIL first looked in his eyes when he logged in for the first time.

"...This is real, right…? Somehow, I actually...want this to be real…"

For how long he simply stared at the view before his eyes, Eidolon could not say. He had already lost count of time, allowing himself to take in every little detail that was so foreign to him.

But eventually, he did snap back to reality.

"Beautiful as this is, I need to check on my Skills. Gotta know I can count on them if the need arises." He pondered for a long moment on what he should try out first. His important Skills mostly derived from his racial levels, so that is what he knew he should focus on. "The basics, then. [Void Step]."

[Void Step].

A Skill that allowed him to become intangible for a moment while moving forward at high speeds, also becoming invulnerable to damage if timed just right. Sort of like a dash, really, one he could perform while flying, as well. The next attack was also sure to become a critical hit if it landed as well, so definitely one of his Skills he implemented a lot in his fighting style.

The lore behind it, if one could call it that, was that his race could tap and connect with their realm of origin for a single moment, somehow phasing out of the physical realm and moving through the Interstice as they advanced forward.

As for the visual effects of the Skill, all that Eidolon should have noticed as far as changes went were his UI becoming slightly blue-hued, not unlike how [Abyssal Cloak] made everything look like a blue-filter had been applied to them.

When [Void Step] came to an end and the scenery before him changed from a mountainous area to a dessert devoid of all manners of life, however, he knew something was very, very wrong.

'...Oh shit. Don't tell me the lore...became real as well…'

Then he heard movement behind him and looking over his shoulder, he realized he was under attack.

'...Shit on a stick, fuck.'

If you are wandering about my OC's race and classes, well, I kinda forgot what I was going for back then in 2016 or 2017.

The main ideas was that his Race is a rare one, Spectral or Ethereal in origin (again, I don't remember what I was going for exactly), and that he is mostly a slippery damage dealer.

As in, he has good Stealth abilities thanks to his race, and his job classes are mostly martial and focused on blades, so he jumps in and out of Stealth, attacks, then becomes invisible again.

He also has Skills that allows his to phase through attacks, but it's a high-risk, high-reward tactic since it needs to be timed correctly.

Remember those games where you have to press a certain button at exactly the right time in order to win the 'clash' or to over-power your opponent?

Something like that.

If he wants to phase through an attack, timing is absolutely crucial. Too soon would undo the Phasing and he would still get hit, too late and he will 'materialize' while the attack is going through him, resulting in a critical hit for him.

As far as Magic goes, he can't use it unless he uses Items like Ainz's pendant which granted him [Fly], but some of his Skills and Auras do have AoE range so he's not just a melee fighter.

As for the five swords gimmick, I was thinking each blade does another kind of type of damage (Fire, Moon, Wind etc), and that one of his job-classes or racial Skills allows him to stack effects on opponents.

Too OP?

Yeah I don't care. This is Overlord.

Too unbalanced and weak?

I dunno, if you think so let me know why and what can be done to balance him out.

After all, I didn't really go into detail with this first Chapter so I still have time to change some minor things.
