Nigredo, Albedo, Citrinitas and Rubedo were the four stages of the Magnum Opus. While most believed that Tabula only created three NPCs, skipping Citrinitas like many writers after the 15th century. But what if this mysterious NPC actually existed? What if this NPC was transported to the New World? How would she interact with this new environment? And is she truly alone?

Nyoko Kokutan, es una joven que por accidente perdió la mitad de sus piernas, y a su familia, triste por lo acontecido se sumerge en el mundo de Yggdrasil, y conoce nuevos amigos, y tiene una estrecha relación con el overlord Momonga, que se tratan como hermanos. Al terminar Ysgrassil, la joven se transporta al nuevo mundo. Nyoko o mejor dicho Aradia, ayuda a Momonga a expandirse.

The Sunlight scripture's desperate weapon was not an angel, it was a race change item. Ainz's humanity is restored... and that's a problem. The butterfly effect results in many changes. Some die who lived, some lived who die, but still the will of Nazarick in this retelling, will not be denied. His level cap shattered and his humanity intact, what happens? Read on and see.

¿Qué harías si supieras que un milagro esta por suceder? ¿Cómo lo aprovecharías? ¿Te arriesgarías a cambiar las cosas?...¿y si no sucede? Tengo mil y una preguntas parecidas rondando por mi cabeza, eta oportunidad es única en la vida, por mas imposible que parezca tengo que intentarlo. No sabría a que aferrarme si no fuera a esto.

AU grim dark/fantasy rewrite: A maddening secret lies at the end of the New World, while an undead fiend corrupts everything that is still good. The only hope that remains: a villain born from a nightmare. / What if Suzuki Satoru had scored higher in the dark triad?

Ainz takes a month before the end of YGGDRASIL to grind and have as much fun as possible, determined to have everything in the game somewhere in nazarick before the game shuts down. This will definitely change some things in the new world!

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.

Momonga is reincarnated into Yggdrasil as his player character, but instead of a skeleton/lich, he is a generic "demon lord" character, and his libido is intact. Most of the male mainstay characters have been gender-swapped to female (Demiurge, Cocytus, Mare, etc.). Basic retelling of the anime but with the gradual formation of a harem for Momonga.

Momonga arrives 1000 years earlier with only his Guild Weapon in his hand. How will the God of Death change the course of history? Instead of conquering, he dominates the new world with his absolute powers.

Five hundred years ago, the Eight Greed Kings walked the New World. Through their strength of arms and magics, they sought to bend all to their will - But, in their avarice, fell to strife and slaughter. The end for one world is the beginning for the next: This time, as a new wave of Players descends upon the land, can anyone survive? Will anything?

To regain a fraction of his humanity, Ainz attempts to create a spell capable of countering his emotion suppressor: but the incantation is more potent than expected, and Suzuki Satoru finds himself irreversibly restored, in the flesh! As more and more people find out and misinterpret the transformation's purpose, will Ainz be able to uphold his façade as the infallible Overlord?

Suzuki Satoru wanted nothing more than Yggdrasil to continue on forever, but they say all good things must come to an end, On the last day of Yggdrasil, he made sure to make the most of it with a day filled with raiding Guilds, visiting old haunts, and a grand display at the end, he had no idea that not everything good had to end, for him, this was just the beginning (SMUT AHOY!)

Basic premise Suzuki Satoru (Ainz) becomes Shalltear if you want a more in depth summary open it and read the summary inside

YGGDRASIL is about to end and Momonga is all alone, but instead of staying that way seven of his former guild mates show up, with more then a few new items

Suzuki Satoru se ve transportado junto a su base de gremio a un nuevo mundo , pero sus sirvientes son altamente agresivos contra los humanos y el no llego con su avatar de no muerto

The entirety of Ainz Ooal Gown, all 41 members, find themselves transported into a whole new world on the last day of Yggdrasil. How will a guild of 41 all-powerful heteromorphs change and influence the events that happened in canon, while also creating entirely new events to explore? For you, the dear reader, this is a tale best told as a theory, a theory on godhood.

On the cusp of conquering all of the New World, Ainz is confronted by the final boss: Queen Elizabeth II. One-shot. Crack.

The story of a man who just really wishes death would let him be. He tried once. Lived a wonderful life, died at a ripe old age. Yet once more he lives in the body of a young child. Time has torn his life's work away, and his only skills are ones from a time long past. Lost, he stumbles upon a game he recognizes. He asks himself… why be a King when you can be a God? (Contains smut)

Just a little short story depicting an imaginary conversation between the Supreme Being Yamaiko and her creation, Yuri Alpha.

A confused Overlord arrives in a New World lost and alone; see how he will deal with all kind of situations while becoming the obsession of a certain Witch Princess whose destiny will be changed forever by a chance encounter! (M because of Overlord stuff and a certain yandere. NO OC player)

Tony knight was your average young man he liked to watch anime and play video games. One day as he was walking home from work he came across a young lady in need of help as she was about to be robbed and killed. Tony killed the assailant but ended up getting a fatal wound. As he lay on the ground dying, he wished he could have done more to help the innocent.

A reverse Isekai of the Overlord story. Instead of Momonga being sent to the new world. The citizens of Nazarick are sent to his. Powerless in front of his friend's creations how will he far?( I don't own the cover Image)

Following the incident in the cave, Lupusregina's behaviour has shifted. She frequently leaves Carne village for hours at a time, coming back smiling and carrying a funny scent. Events get set into motion, when her odd behaviour one day gets noticed by a foraging goblin. (SEQUEL TO ALBEDO'S SEXUAL ESCAPADE, RATED M FOR MUTURE CONTENT)
