Between Ainz Ooal Gown and Albedo and Demiurge and Shalltear Bloodfallen as siblings.
The vast halls of the Great Tomb of Nazarick lay silent, save for the gentle hum that seemed to resonate with magic and ancient purpose. Undisturbed for countless ages, this moment of tranquility was shattered by an arcane shockwave that rippled through the foundation of the underground labyrinth. It was a force unseen and powerful, tearing like fabric, warping the very essence of reality itself.
In his throne room, the supreme overlord Ainz Ooal Gown, formerly known as Momonga, sat motionless on his throne. His skeletal hands poised thoughtfully over the armrests, his red pinpoints of light that served as eyes sensed the disturbance. The eerie calm that followed was what unsettled him the most. It was as if the world held its breath, expectant, fearful of what had just transpired.
His guardians and most loyal servants were quick to his side, ready to serve and protect. Albedo, the overseer of the Guardians, glided to him, her beauty and grace undiminished by the urgency of the situation. Demiurge, the cunning tactician, followed close behind with Shalltear Bloodfallen, the true vampire, carrying her usual air of both nobility and bloodthirst.
But then, reality shifted. An overwhelming force engulfed them, and a flash of blinding light consumed everything.
When the light dissipated, Ainz and his guardians found themselves in what appeared to be an otherworldly version of Nazarick. The grandeur was familiar, yet the atmosphere was entirely foreign. Confusion broke the silence as they looked around, trying to make sense of their surroundings.
Ainz spoke first, “What has happened? Report at once!” His voice, commanding and deep, echoed through the altered chambers.
It was Albedo who replied with an uncertainty that was rare for her, “My Lord, I cannot ascertain our current situation. But it seems we are still within the walls of Nazarick, yet everything is... different.”
The others voiced their agreement with unease. It was Demiurge, ever the analyst, who noticed the strangest anomaly first. He spoke with a cautious tone, “Everyone, look at your hands.”
As they did, revelations dawned upon them with a mix of horror and disbelief. Their forms had changed. Ainz, who had been accustomed to seeing only bones, now beheld flesh upon his hands. He stood, his height remaining but his skeletal form replaced by that of a living human. Albedo, similarly, found herself looking more mortal than divine, her wings gone. Demiurge's demonic features had softened, and Shalltear looked startlingly younger, her vampiric traits subdued.
Then came the memories, flooding their consciousness with fragments of lives never lived. They remembered a past as siblings, the children of Nazarick, each born with unique talents and aspirations. Ainz, the eldest brother, was no longer an overlord, but a protector of his kin. Albedo, the second eldest, carried wisdom and the legacy of the tomb's magic. Demiurge, the cunning brother, wielded strategic mastery. And Shalltear, the youngest, now bestowed with human fragility, was the heart of their family.
Ainz looked upon those who were once his servants, now his equals in this surreal family. “We must understand what has transpired and what binds us in these altered forms. We are no longer just guardians and a master; we are kin. Our bond is what will unravel this mystery.”
Despite confusion and the uncertainty of their new reality, a sense of resolve took shape. The family that stood in Nazarick's altered halls did not yet grasp the entirety of the forces that wove their destinies together. But one thing was clear; together, they would face any challenge, armed with the strength of the ties that now connected them—bonds as deep and as ancient as the tomb itself.
