The Overlord of Mysteries

Hello, this is my first time writing a fanfiction. If you notice any errors, please feel free to give me constructive feedback. English is not my first language, so if you notice any mistakes, please mention them in the comment section at the end of the chapter. Let's begin the story!

Word Count: 2700 Words

Note: Just a reminder that I've changed the Guild Auxiliary chapter. I've made some changes to it. I've removed a couple of NPCs and added a few.

Due to my college work, I was unable to upload the chapter.

Next Day [Mc Pov]

For now, I can conclude that I have mysteriously travelled to the past. As for the current timeline, I am not that well-versed in human history.

I did spot a primitive style of living, but there are villages, and they have fire and huts.

So I'm at least not in stone age.

For now, I should find a way back to the twenty-first-century Fuyuki City. As for how I am sure of this being Earth, I spent the night on Mars.

If this is still Nasuverse, I don't plan on fighting the Red Moon by spending the night on the moon. Which was quite tempting. Sleeping on the moon is a great dream but to fight the Red Moon or the Vampire Ancestor for it is not worth the effort.

It was quite productive, I have at least confirmed that I can survive in space. This is quite a durable body I have.

I considered my options moving forward as I looked at the village in the distance. I had been spying on the village for a couple of hours. Life in the village is quite simple, they get up at sunrise.

Men leave the village to hunt and also get wood while women procure water, fruits and vegetables.

It is an ordinary village except for it having shamans.

I had cast perfect unknowable as I entered the village.

These guys worshipped a strange statue of an animal resembling a wolf.

I left the village at sunset after checking it out. I walked to the forest near the village. It is a good place to camp. It has mountains with many caves. A perfect spot to rest till I find my way back.

I haven't been able to return with Gate or Teleportation. Will just have to wait till I can find a way back. With this body being immortal, there aren't a lot of things that I have to worry about.

I don't wish for this, but I, for one, definitely do not wish to pass my time here till this place progresses and I live in hiding till the fifth Holy Grail War. Nor can I interfere with history, so worst case scenario I stay hidden.

One Week Later

Bruce sat on a throne he had created using Create Greater Item in his makeshift home he had made inside a cave. To make it more comfortable, he had chosen the largest cave among all the surrounding mountains.

'This Earth should still be in the Age of Gods. Going by the situation in the village, I have travelled in time to even before Gilgamesh or Karna were born. Still, this is quite a dangerous place that I have found myself in.

Though I am a God myself. At least in the title, but that wouldn't matter to these Overpowered Gods.'

Bruce, unwilling to bet his life on his luck, had got to creating a bomb if you could call it that. Since he had only a small amount of Caloric_Stone. He used them with the Silver Apple, the next high-level ingredient on him.

Experimenting with his God of Runecraft prowess, he tried studying his Heart of the Fire Dragon, Sword of Ra and The Form of Rising Sun. Trying to Crack the runes and scribbles on the World Items to recreate another item on the same level as these World Items.

'This should be a good policy against them. I can't use The Form of the Rising Sun if possible. I can't go on a search to find it after its use, that is, if Earth survives the attack. As for the rest, I'll be making new enemies rather than dealing with old ones by using them. Gods chasing me for creating a replica of their most beloved treasures.'

The project had begun the very night he was summoned. Finding himself in Nasuverse and getting access to Zouken's library and items prompted him for this. This also doubled as a way for him to check his prowess and lore.

The effect of lore and titles had on him.

Moreover, if he wished to study space and time-related spells to try creating a way back for him. It would alert the Gods of this world.

It was a dangerous endeavour.

Six Months Later

Bruce kept the silver apple, which had taken a Reddish Golden colour, in his inventory as he stepped outside his cave in his Golem Avatar. He had been holed up in his cave trying to create a World Item.

Something that should have been an impossible task was showing promise. It looked promising, and if he were to keep at it, he could get it to the level where its power surpasses most World Items despite not being a World Item.

It was an item built with the knowledge of Overlord Verse and Nasuverse.

'Hmm! The knowledge from Zouken's research and his library was eye-opening. With this World Destroyer I'm building, it should be almost as strong as The Form of Rising Sun, except it doesn't work on the concepts of its purpose as Destruction of the World. The Form of the Rising Sun would destroy this planet, or, at the very least, if powered enough, would also engulf the whole solar system in the blast.

The concept of the World is very vague. What qualifies as a World here? Is it a planet, or is it the whole universe? It was very clear in the game, but here, it just raises more questions.

However, the creation of this item could have been impossible if not for me being in Nasuverse. In Overlord Verse, I couldn't have made much progress with this item in the same amount of time. The knowledge I have acquired here is going to be very useful for my future.'

Bruce or Optimus walked towards the exit which also doubled as the entrance of the underground cave where he had built himself a home.

'Maybe I should check up on that village. There were few of those, hmm! Priest might be the word. They were worshipping a zombified version of a wolf statue. Might be a local deity. They did use some interesting magic back there.'

Light radiated from Bruce's body as he turned to his human form, Vishanti.

'I can't leave any proof of my existence here. So a human form is a good cover when I leave the cave. While the experiment can be done in my Golem Form. The Fool will have to wait till the twenty-first century.'

Bruce had been living alone in the cave for half a year now. He had been living alone in a cave, managing himself alone, and for food, he had the food creation carpet, which he had created for fun, just like many other items in his inventory.

Bruce walked down the mountain closely observing the trees and plants in the forest. Bruce turned back as he observed Sakura leaves fall in the distance.

'A storm of Sakura leaves?'

Unknown PoV

Deep within a forest, seventy-seven monsters stood facing a small white-coloured dog. The dog was cornered against the tree trunk as it eyed the monsters surrounding it. They had cut off all escape routes he could have taken.

'Ancestral Wolves.'

It thought about their race as it saw them closing in. It had hoped for this to not have happened. This was forcing it to use its prowess.

Pink petals, or what some would call Sakura petals, gushed out as the little dog raised its paw. Causing confusion to spread among the wolves. The petals had done their job. It had finally secured itself a path to escape. Blowing away the wolves on one side.

It wasn't a very good experience. First, that damned Incubus Mage that threw it from the tower. It had been sleeping peacefully far away from the struggles and cruelty of the world and humanity or that of monsters.

But the Incubus had to throw it out, disturbing its sleep. Now, it was stuck fighting these monsters who were serving the corrupted divine totem spirit worshipped by the humans in the nearby villages.

Cath Palug ran trying to get away from these monsters. It was not in the mood to fight these monsters or their Master. Who could only be wishing to devour it? To inherit its prowess.

It stopped in its tracks. It still hadn't escaped from the wolves nor got out of their encirclement. As it sensed its doom. The wolves were too ignorant and weak to even detect the danger they all were in. It knew for sure that the presence it detected was not of the Corrupted Demi-God Wolf.

The Presence was very different than anything it had felt before. It hadn't come across any being with similar aura or presence. The Presence vanished as soon as it had appeared.

The wolves oblivious to it, surrounded it again. It tried racking its brain for a way out when it heard a human voice.

"What do we have here? Few ugly wolf-like monsters ganging up on a small puppy."

Cath Palug raised its head to see the owner of the voice. A man was sitting on a branch of the tree adjacent to it. It shocked Cath Palug that it had failed to notice the man till now.

The man intrigued it. Enough for it to try to get a glimpse of the man from the hood of the cloak the man was wearing. It was a grand dress, enough to put even the incubus mage's wardrobe to shame.

It was then that it made eye contact with the man. The red eyes sucked it in as it watched numerous single-eyed worms forming a humanoid shape and the Dark Cursed World. Which could be their home and the Grand Temple where their God resided. This reminded it of the presence it had felt earlier.

Fear took hold of it. Cath Palug had never felt fear or knew what it was. It had been living its life remaining oblivious to all the struggles of mankind. For the first time, I had come across something that couldn't be explained.

The causality curved and distorted in his presence.

Just when it thought that everything was over. Strength gave out, it hadn't eaten in a long while. The weakness took over its body as it fell. Though it managed to maintain its consciousness.

It had to watch as the Man, it would be wrong to call it a man. It was something more. It was a nightmare, an Eldritch Horror. The Eldritch Being jumped down from the tree branch and picked it up. Cath Palug watched with wariness. It watched as the being raised its arm towards it; in response, Cath Palug closed its eyes in fear. Awaiting its death.

Instead, it was shocked to its core to find the arm petting it.

The death it had expected was not there. Instead, it saw the Man pet its fur. Moreover, the being had taken out a fruit with some magical means and brought it towards its mouth. Though cautious of it, the hunger took over Cath Palug as it devoured the fruit. It took a single bite out of it, cautious of the fruit. Seeing that it was still good, it ate the whole fruit. It wasn't sure what it was about the fruit but it couldn't control itself.

Its hunger had blinded its sense of danger as it realised that it had eaten food provided by an Eldritch Entity without a care in the world. Afraid for its life, It moved around in the Mysterious Man's arm as it checked itself. After checking for any external injuries and making sure that it was feeling normal and was not having any abnormalities it looked at the Man.

Wondering for its fate that this Eldritch Entity had decided for it.

Thinking of its fate, it remembered about the monsters that were chasing it. It grew curious about their current condition.

It was uncharacteristic of them to remain quiet for this long. Those mindless monsters would have attacked them without a care in the World.

He decided to check out their situation for himself as it snuggled out of his grip by a bit as it watched where the monsters were standing earlier, only to find the whole perimeter empty except for itself, the Man and some insects and birds loitering around.

They had vanished without leaving a trace behind. It grew curious of their condition as it turned to look at the most probable candidate for this incident.

It was petrified in fear as it was reminded of the scenes it had seen through those eyes of the Eldritch Entity.

Not wishing to suffer the same fate as those foolish monsters, it remained silent and obedient as it let the Man carry it.

Contrary to The Dog's thoughts for the whole debacle, Bruce was quite surprised with himself. Especially since the dog he got acquainted with was not a simple magical beast that is found easily in this world.

'Who would have thought I would get to meet Cath Palug or the one famously known as the Primate Killer? One of the Beasts of Fate verse.

It is quite meek right now. Does it feel indebted to me for saving it and giving it a fruit? It is snuggling up in my arms. Compared to other Beasts and monsters my opinion of Cath Palug or Fou is very favourable. So, am in FGO now. And does this change canon now that I have picked him up? Will his meeting with Mash not happen now?

I can think of it later, but for now, let's take this little guy or this little Beast back home.'

Bruce brought Cath Palug up to his eye level and inspected Cath Palug for any injuries as he cast a healing spell.

'Well, I am not sure why he was having such a hard time against such small fries. A healing spell should be able to deal with any injuries he might have suffered in that stand-off.'

Cath Palug stood alert as it sensed the Eldritch Entity cast a magic spell. It was cautious; its fur stood on ends. It remained still to not anger the Eldritch Being and to not suffer an even worse fate than what it was going to. But as the magic circle formed in response to his cast, it was very surprising. It was unlike any magic circle it had ever seen. It wasn't just the magic circle, the working mechanics of the spell were also alien to it.

But its effect surprised it. Its body relaxed as Cath Palug allowed the magic spell to heal its body. It was a refreshing feeling. Cath Palug raised its head to see the Being, growing doubtful of the things it had seen a while back. If it had all been a dream.

It allowed the Man pet its fur, trying to take another look at the man inside the hood. It felt a power in the Man's eyes that was trying to suck it in.

Reminding it of the fact that everything it had seen was not a lie.

Still afraid of the Man, Cath Palug stayed still resigning itself to its fate. Still, it enjoyed the feeling of being pet by the Man. At least it was safe from the Wolf for the time being.
