I took inspiration from all the Overlord and Danmachi stories I have read and thought of writing my own, please ignore some grammatical mistakes as English isn't my first language.
Orario, The city of gods, the center and the largest city in the world. Here thousands of people come here daily to either start a new life, become an adventurer, or just plain old finding beautiful women. What is so special about the city you may ask, well here lies the world's greatest and only dungeon on which the entire city economy has been built. In the very same dungeon, we could see a rabbit being chased by a bull.
"Uroooooooarrrrrrrrrrrr"
"Aiiiiiiiiiieeeeeeeeeeeee?"
I'm about to die basically I am being chased by this man-beast of a monster, Minotaur. What did I think I will come to the dungeon, play hero save beautiful girls make a harem of my own, 1000s of girls will be after me of all kinds be it amazon or elves, or beast girls. Ok the last part was too much but 3 to 4 is still needed in a man's life, That's what my grandpa said. Sorry, grandpa, I will see you in heaven.
"Urugaaagaga"
"Daah"
The minotaur hoof came crashing down on me. Somehow by some luck, it missed and hit the ground. However, luck was fully not on my side and I got sent flying due to the air pressure created by that attack.
"Ahhhhhhhhhh" My shoulder has been dislocated and I have been backed into the corner. I guess this is the end. Minotaur picked up my fear somehow and it smirked?! I guess at least someone is having a good day only if it wasn't at my expense.
It raised the weapon and came swinging at me. I just closed my eyes, At least my death will be painless. However, said death never came, what did come was a pool of thick liquid sprayed all over me and I opened my eyes to see a blade poking out of the minotaur's abdomen. Then there I saw her, killing the monster with such grace, and in an instant monster turned into dust.
Time stood still for me as the last of the monster's blood poured over me.
"Are you okay?" She asked quietly. I stood still and saw her. A female warrior with golden eyes and hair, clad in light blue raiment. Even a Level One newbie like me knows who's standing there.
There's no mistaking Loki Familia's Aiz Wallenstein. Everyone knows she's achieved the highest rank among humans, no… all-female races, Level Five.
"Umm… are you sure you're okay?"
No, I'm not okay. Definitely not okay. My heart feels like it could explode and fall to pieces any second. That is not "okay." My cheeks blush as I gaze upon her with sparkling doe eyes. Love is about to bloom… no, love is erupting within me. My soul is gone, it's hers now. Then I ran past her in an instant completely ignoring her and achieved a speed not possible for a level 1.
Aiz stood there shocked as the human she saved ran past her at a speed that would make level 3s drop their head in shame. "Am I really that scary?"
Besides her Bete loga another level 5 of loki familia was laughing like a madman. "You really did scare that brat Aiz bahhahhahahha" Aiz pouted at that she definitely wasn't that scary.
Then Bete stopped laughing "Was that the last of the minotaur that escaped from the middle floors?".
"Yes" Aiz responded. "I see, Let's retreat back to the party and inform Finn that no casualty has occurred". Bete said
"Yes" I put the minotaur stone in my bag and make haste. There have been a few odd phenomena in the dungeon lately and no one knows the cause of them. Not even gods.
Little did 3 of them know they were being observed by a space-time anomaly.
Near the Great Forest of Tob lies a mausoleum. The tomb consisted of 10 floors each with its own Floor guardian. In the throne room sat the King of Death himself, Ainz Ool Gown. It has been 10 years since he had been transported to the new world and since then he has conquered the whole world. Turned countries to ashes and whoever stand in Nazarick way.
The biggest threat that posed were Dragons however with Theocracy out of the way and all the treasures of 6 Great Gods in possession of Nazarick and with World Item "The Downfall of Castle and Country" Ainz turned all the dragons into his puppets and now they are part of Demiurge Happy Farm (ᗒᗨᗕ). Now the great Dragon's skin is being used for Magic scroll creation up to the 10th Tier.
However, after conquering the entire world Ainz still wasn't able to find any way to break his level cap. (A/N: I forgot about volume 14 so i will just stick with level 100 Ainz) Not that he needed to but he wanted to. By his side stood, Albedo one of his loyal subordinates/Bride (Self Proclaimed) with a smiling face as always.
Below the Throne room were all of Nazarick's high-level denizens including the floor guardians.
"Rise"
There was a pause of a few moments and then all the Guardians raised their heads in unison. After that all their subordinates.
"Man I wish they would stop with their reverence" He monologues in his mind. Oh well after a decade I should know that their loyalty is so over the top. Enough with inner monologues.
"Demiurge, Report and tell me everything that is happening around the Sorcerer Kingdom. Albedo has given me a report earlier however I would like to hear from you and know your opinion" He says in a regal voice.
"You flatter me, Lord Ainz but I know you have planned everything" Demiurge states with such confidence that I sweat drop despite being a skeleton, and all the Denizens nod. "Uwaahhh such dedication, it never gets old despite seeing this for a decade now".
"Yes, Thanks Demiurge now please continue with your reports, and if there have been any anomalies around the kingdom?"
"As of now, Everything is going well Lord Ainz as Albedo reports state. However, in the center of the Forest of Tob, there seems to be a magical anomaly that is it leaking some amount of mana. Fluder did research on this and said it's a space-time phenomenon."
"I see, Please continue" A space-time phenomenon heh? Could this be a portal connecting to other places?
"Yes, Lord Ainz. As per his reports, it's a portal that is connected to a dungeon. However, anyone above level 70 can't pass through that portal. That still requires further investigation."
"A portal to a dungeon you say" Hmm I wonder what is there in that dungeon.
"I hope an exploration unit was sent to that dungeon and this is being kept wrapped" I don't want a chance of getting more resources spread through the whole world.
"Yes Lord Ainz besides Fluder no one outside knows about this."
"Great work Demiurge and what have we found so far in the dungeon" I hope it's something useful like prismatic ores and stuff.
"Yes, There are monsters inside the dungeon of insignificant strength however they do drop what seems to be concentrated mana turned into stones, Experiment on this is still ongoing and I do have a few samples if you would like to take a look" Demiurge took out few football sized magic stones from his hands. Yuri took magic stones from him and gave it to me.
"Hmm, That's quite heavy I wasn't expecting such depth" "Item appraisal" Casting a magic spell on the stone revealed it is made of pure mana and consists of what appears to be a broken soul. Interesting, Handing back the stone to Yuri I observed Demiurge. He seems to be smirking.
"There seems to be a broken soul trapped inside that of stone I am sure you can make something useful out of it for Nazarick. Have you put the stones in the item converter?" It would be helpful if we could farm more Yggdrasil coins as items from the new world have such a bad conversion ratio.
"Yes Lord Ainz a magic stone of this size gives about 10,000 Yggdrasil Gold."
That's a good quite the huge conversion ratio and I was expecting something along the lines of 1:1. This solves our currency problems of the near future as long as the Dungeon can sustain the output. Nazarick may have trillions of gold in its treasury but in the end, it's still a finite amount and with all the Denizens that are immortal there will be a time it runs out. Can this newly found Dungeon support it?
"Demiurge what are your observations of this dungeon?"
"People that were sent into Dungeon have reported that it has 79 Floors. Its core is at the center of the 79th floor and is about 400SqKM in size and 813 Million Tonnes in volume with huge vines powering the whole Dungeon and it doesn't seem to be losing power. On the contrary, it's gaining power which is a good sign as we can mine the dungeon without any issue of it being depleted. Every 10 floors from the 18th there is a no monster zone and every 10th floor from the 17th there is a Boss Room and all of them are disgustingly weak all the way to 77th floor as per reports of Level 67 Assasin we sent for investigation." Demiurge concluded his report.
"I see any humans or demi-humans exploring the Dungeon?" I ask if it would be annoying to have humans mining the dungeon.
"Apparently scouts have seen a lot of Dungeon explorers all of them being weak however scouts couldn't get past Floor 1 because some sort of divine barrier blocks their path, However, we sent a human from Slaves of Slane Theocracy and they were able to get past just fine. As per slave, it is like a whole different world out there with a tall tower piercing the sky, We have erased the slave memory and sent it back to Happy farm" Demiurge concluded.
Another world eh? Interesting finally something to explore. But that barrier raises the question of what is blocking our way to the surface and why can only humans get past it. Maybe elves or demi- humans can get past too?
"Can you describe all the inhabitants that are not monsters found in the dungeon" Maybe they have some sort of blessing to go into Dungeon? This requires further investigation.
"They seem like Humans, Demi-Humans" Demiurge's brain started comprehending what Lord Ainz said, maybe there is another world that is out there for Nazarick to conquer. If yes he will find the phenomena that are causing them to be kept out.
Albedo and the rest of the guardians were also listening to the reports and came to the same conclusion if there is a world out there they will gift it to Lord Ainz.
Ainz completely oblivious to their guardian's thought was excited to finally find something interesting. He pulled out the "Mirror of remote viewing" from his inventory to check if he can peer through the Dungeon or not.
"Chain of clairvoyance" He cast the spell to connect to the Mirror for better insights. Now all he needed was coordinates. "Demiurge, Coordinates please"
" It's 77N, 64S with a magical depth of 0.2 factor 7" Ainz set the coordinates and he had a view of the insides of the Dungeon. He saw Floor bosses and monsters as described by Demiurge and also Humans at what appears to be Floor 49th dealing with some caterpillar-like monsters. From their magical signature, they appear to be ranging from level 14 to 34. With a dwarf being the strongest among them.
"Interesting they also have a slither of divinity on them just like my divine equipment"
"Maybe they are blessed by some lesser deity?" Commented Albedo.
"Maybe a further investigation is needed" Then he panned to floor 18th. There he saw people who were significantly weaker than the ones on 49th. But all of them had the same fragment of divinity on them. Maybe albedo's comment is correct.
"Demiurge can the humans from the dungeon cross this dimension?" If they can we will Kidnap someone in the range of level 10 to 14.
"We haven't tried that but we can test it out my lord" Demiurge berates himself in the head for such an obvious blunder but also praised Lord Ainz for coming up with a plan for more information gathering.
"I see, How long will it take to Capture someone from floor 18th all the way to the portal for our scouts?" I hope it's not a few weeks.
"It can be done in a few minutes Lord Ainz since all of them know "Greater Teleportation" Demiurge wanted to give an instant result but couldn't.
"Excellent get to it Demiurge, If they can pass through our barrier collect every single strand of information about this new world from them. Albedo I want a report of it on my table in a week, If they can't pass through our barrier interrogate them into the dungeon itself. Send our best scouts under level 70" Ainz concluded.
""Yes, Lord Ainz"" Both said resolutely.
"As for rest, I want you to be back to your assigned posts. "Greater Teleportation" Ainz left the throne room.
"I will excuse myself then," Demiurge said and all other Guardians and Denizens went back to their posts.
What both Ainz didn't know was this decision would lead to the complete and utter misery of 3 adventures.
A few days later back in his room, Ainz was still observing the Dungeon like the child who got his Christmas present and came across a hilarious scene of a rabbit being chased by a bull and then being saved by a golden princess. He came across a lot of this scene and it has become his hobby to watch dungeon now.
He saw all kinds of monsters that were being farmed by Demiurge's subordinates, a few talking monsters which he found interesting. Also, the people that got kidnapped are now under the custody of neuronist.
A few days later a big fat stack of reports came onto his desk regarding the new world. This report will lead to such misery for our protagonist Bell Cranel, Stick around to find out.
