The group stood together in stunned silence, staring at the enormous sight in front of them. Even for veteran players who had fought gods, dragons, and other guilds for years, this moment felt unreal. It was not every day that someone saw a completely new dimension, one that their own guild had created with their own hands. The air shimmered with soft light, like the sky was gently rippling. Strange stars floated overhead, neither close nor far, giving the place an otherworldly glow. Colors moved in slow waves, like living auroras.
Momonga, dressed in his dark robes as usual, stood in front of the group with his skeletal posture perfectly straight. Even though he had no facial expression, everyone could tell he was amazed. Beside him stood Blue Planet, the guild member known for his obsession with nature forests, oceans, mountains, and everything between. His voice always carried an excited tone whenever he talked about natural beauty.
"Welcome to the house of Hades," Blue Planet said proudly. He opened his arms as if he were presenting a stage performance. "The first ever completed dimension created by the Ainz Ooal Gown guild."
The group murmured among themselves, still taking in the view. The wind carried a soft glowing mist that gently brushed their armor and robes. A river glittered in the distance, flowing upward instead of downward, like gravity had given up trying to control it.
Momonga nodded slowly. "Amazing work, Blue Planet. Truly… amazing."
A few months earlier, none of this would have been possible. Back then, the guild had been struggling in an intense, almost hopeless war against their long-time rivals: The Children of God. That guild had always been trouble strong players, aggressive tactics, and a habit of declaring holy crusades on anyone who annoyed them even slightly. Ainz Ooal Gown had fought them many times, but this last war had been the fiercest. Everyone had suspected that defeat was coming. Even Ulbert, who was usually full of confidence and destructive energy, had been worried.
But then, through teamwork, insane strategy, and just a little bit of good luck, Ainz Ooal Gown crushed their rivals completely. It was the most shocking victory in their guild's history. They gained countless rare treasures from the war loot, including several world items. But the most unbelievable one the one everyone talked about was the Genesis Core.
Rumor had it that the Genesis Core was practically a cheat item. It allowed the owner to create a full dimension, as large as they wanted, and even allowed them to double the number of NPCs they could manage. That alone was enough to make any guild jealous. But of course, as with all world items, it had a terrible downside.
The Genesis Core had extremely low durability. If an enemy ever managed to break through their defenses and destroy the core, the entire dimension would explode with the force of a massive bomb—powerful enough to wipe out half of the Great Tomb of Nazarick in a single blast.
Because of this danger, the first idea the guild had was simple: sell it. Something that risky would only bring trouble. And the price being offered in the player market was astronomical so high that even Touch Me, usually the moral voice of the group, had blinked in surprise.
But not everyone agreed with selling the Genesis Core at first. For days, the guild argued back and forth. Ulbert complained loudly that selling it was a waste. Peroroncino backed him up, saying it was a once-in-a-lifetime chance to make something huge. Tabula added long explanations about "creative potential" and "unique structural freedom," which most people quietly ignored but still appreciated. Blue Planet simply said, "Why sell beauty before we even see it?"
Even Touch Me, who tried to stay neutral, admitted, "A new floor would help Nazarick a lot. Twice the NPC capacity means twice the defense."
And in the end, after all the shouting, voting, and late-night discussions, everyone finally agreed: Nazarick needed a new floor. The Genesis Core wasn't something to sell—it was something to build with.
Once the decision was made, everything fell into place. They discovered that the Genesis Core had a strange ability: it could expand endlessly as long as it was fed gold. And because Nazarick had recently emptied the treasury of the Children of God, gold was the one thing they had more than enough of. Piles of it, mountains of it, more than they had ever owned before.
So the project officially began.
Ulbert was the first to shout out a name with great excitement:
"The House of Hades!"
And everyone agreed it fit perfectly.
Using the ancient stories of the Greek underworld as their main inspiration, the guild members of Ainz Ooal Gown shaped their new dimension into three great kingdoms. But among these three, Elysium was the most special. It was the first region they built, the one every guild member worked on together, and the one meant to reflect their dreams, their pride, and their twisted sense of beauty.
Even though Elysium was based on the mythical land of rest, peace, and eternal comfort, the members of Nazarick could never create something purely peaceful. Their creativity naturally blended beauty with danger, comfort with darkness, and paradise with an eerie sense of awe. And so Elysium became something unique—a paradise crafted by monsters, for monsters. A place filled with wonders, warmth, and luxury… yet underneath it all, a quiet whisper of fear, like a shadow lying under sunlight.
Blue Planet began the design, but every member added something. Even Ainz, calm and methodical, contributed to its structure. Touch Me suggested open gardens with glowing plants. Peroroncino added colorful birds with gemstone feathers. Ulbert insisted on giving the sky two suns—one warm gold, one cold blue. Tabula created floating structures with impossible architecture, buildings that twisted and folded like dreams.
But none of these ideas were purely good. Every beautiful creation carried a darker side.
The libraries Ainz requested were huge, made of black marble and gold veins, with floors polished like still water. But the books inside whispered when read, sharing forbidden knowledge that could drive weak minds insane.
Peroroncino added a music palace that was beautiful… but unsettling. Crystal instruments floated in the air, playing songs on their own. Some melodies were soft and gentle, sounding like feathers brushing against the wind. Others were deep, echoing with haunting voices, as if spirits were singing from the walls. The palace was a paradise for art, but anyone who disturbed the harmony would find themselves hunted by the palace's singing guardians opera spirits with masks of gold and crimson.
Some guild members added questionable places too: Ulbert added a theater where illusions performed scenes of despair for entertainment. Tabula created a garden that bloomed only at night, its flowers glowing red, feeding on magical life. Blue Planet added a sanctuary lake where the water healed injuries, but the reflections on its surface always showed twisted versions of the viewer.
The sky above Elysium was always twilight—never fully day, never fully night. Purple and gold clouds drifted slowly, as if the sky were half-asleep. A soft breeze carried a sweet scent of unknown flowers, mixed with something a bit cold, a bit unnatural.
And deep beneath all these wonders lay the most important structure of all: the secret chamber where Lucifer hid the Genesis Core.
Lucifer, the master of traps and misdirection, took great pride in hiding the core so well that even guild members would struggle to find it. He built layers upon layers of illusions, false floors, shifting pathways, and magical locks. Only the system was allowed to know the exact coordinates. Even Ainz, the guildmaster himself, agreed that not knowing its location was safer.
"Even we must walk carefully," Lucifer had said with a smirk. "A paradise is safest when even its creators fear its secrets."
To protect the core, he added traps that were both clever and cruel. Gardens that swallowed intruders whole. Statues that came to life when stepped in front of. Harmless fountains that exploded into deadly curses if touched. The whole of Elysium was a fortress hidden under the mask of paradise.
Despite the dangers, Elysium was also the military training ground of Nazarick's demonic army making this the safest place for the core.
Great black-and-gold coliseums stood across the land. They were wide arenas where demons, angels, golems, and magical beasts trained daily. The floors were made of enchanted stone that healed cracks instantly, no matter how many spells or claws tore through it. Which was an idea proposed by Warrior Takemikazuchi to test spells and attacks freely.
To the south lay Tartarus, a region Ulbert controlled completely. It was a bottomless pit of nightmares, an abyss filled with eldritch horrors that only Ulbert's twisted imagination could create. Monstrous figures with too many eyes, too many arms, or shapes that defied logic crawled along the walls of the black chasm. Even the air warped around them. Screams echoed through the caverns, some from prisoners held deep below, others from creatures that simply enjoyed their own monstrous voices.
This region was also the prison for the damned—souls or NPCs who committed grave sins in Nazarick's lore. The three judges stood here: Minos, Rhadamanthus, and Aeacus, designed by Tabula and Ulbert together. They were beautiful and terrible, wearing robes woven from shadows and purity at the same time. Their glowing eyes saw through lies instantly. Anyone brought before them faced judgment harsher than any mortal court.
Guarding the pit was the massive pet of this secret floor—the giant three-headed dog, Cerberus. Each head had a different personality: one calm, one savage, and one cunning. The beast slept on a bed of bones and shadows, opening its eyes only when someone dared approach the abyss. And beyond all of Tartarus lay the only true path that led up to the throne room of Nazarick. Only the Ring of Ainz Ooal Gown could bypass the countless barriers and illusions protecting it.
To the north of Elysium stretched the Asphodel Meadows, a silent sea of silver grass that moved like waves even without wind. Blue Planet designed this place with great care, combining tragedy with beauty. The moon above shone brighter than any sun, bathing the land in pale white light for eternity. Souls wandered gently through the fields, their forms soft and hazy like living mist. They had no memories, no desires, and no pain. It was peaceful, but also deeply lonely.
Rivers from myth flowed through the plain, each one magnificent in its own way
