Sometime after the revival of the renegade Shalltear...
Chaos gripped the denizens of Nazarick.
Like ants, they scattered around, unable to grasp the situation. Reports flew unsubstantiated, most of the time rife with falsehoods and blatant assumptions. Duties were left abandoned, each floors shook periodically as if from a massive earthquake-even the mysterious denizens of the eighth floor wondered if Nazarick were about to fall.
Most worrying of all was the Overseer's refusal to remedy the situation. In fact, most didn't even know where Albedo was, nor what had made her abandon her sacred duties in glorious Nazarick.
The immediate answer-the source of all these troubles-if it is to be believed, lay prone on a bed in the 9th floor, watched over anxiously by a cadre of the homonculi maids.
A bewildered Demiurge, frantically recalled from his duties by his servants, stood outside the room. He had a puzzled expression on his face. Some of the other homonculi maids stood outside too, whispering in buzzing noises among themselves.
Singling out one maid, whom his perception found to be the most knowledgeable of the situation, he dragged her to the side.
"Tell me what you know," he said, adding his compulsion aura to his voice. The maid nodded and began to recount the tale:
The Master and the Overseer were discussing matters of importance in the throne room. It was just after Cocytus had been given his assignment to subjugate the lizardmen tribes.
Then-and the maid wasn't sure about the exact moment it had happened-there came a flash of light. All the guards inside the room, including Ainz-sama and Albedo-sama, instantly went on alert.
A moment later, a young girl now stood at the foot of the throne.
"Assassins, assemble! Protect the master!" Albedo yelled, interposing himself in front of Ainz-sama. The latter was speechless, even his magnificence quenched by this sudden development.
The guards had the small figure pretty much surrounded. The Overseer was quick to demand, "Who dares enter the Supreme One's presence without permission! Speak, or die screaming in the abyss!"
The invader just smiled. She had no eyes for the fearsome Overseer, nor for the guards whose weapons were poised to strike her. If nothing else, she was bold and confident, even in the presence of superior beings.
"Hello father," she told Ainz-sama, "I have returned. Tell mother."
"Father?" Demiurge cried, choking in surprise, his eyes actually widening. Even his unruffled demeanor was disturbed by this revelation. Just one word implied many things, and changed virtually everything.
Nonetheless, in the next moment, his eyes narrowed, calculating, as he contemplated the closed door where the invader was.
"Pray continue," he said, "And leave no details out."
A tense silence. The Overseer's expression darkened with every second.
"Such impudence!" Albedo roared, her normally beautiful visage distorted. A potent rage seemed to be simmering around her body, manifesting in a cloying aura that made even the guards pause. "Lies upon lies! How dare you insult the name of the great Ainz-sama!"
But it didn't seem to affect the newcomer. The maid now took a closer look at this intruder: it seemed to be clad in some strange gear, almost like a gaudier, more revealing version of Aura-sama's outfit. Her skin was pale, though sun-tanned. She had long black hair, tied up in a ponytail. A small scar was clearly seen on the bridge of her nose.
"Oi," she said, flashing cold eyes on the livid overseer. "I wasn't talking to you, bitch. Go spin your webs somewhere else. Now is the time for me, my father and my mother."
Just before Albedo could shout some more, Ainz-sama cried, "Silence!"
His voice shook the very foundations of the throne room, easily wiping the smirk from the intruder's face. All of them, even the intruder, kneeled before their lord, and begged forgiveness.
"Nn... Umu- Yes, let us put things in order first." He pointed imperiously at his so-called "daughter". "Y-you say you are my get? Then prove it, little one, while my patience endures."
"Of course, father," the girl said readily. She rose, and reached into her pocket. Albedo tensed, as if waiting for an attack, though the Master remained still, as if all such efforts had long been foreseen. And indeed, his foresight was justified, as the girl had merely taken some sort of token from within her pocket, and held it out for the lord to see.
"This is..." One could sense the tension so palpable in those moments. Ainz-sama stared at the object, transfixed, while Albedo and the rest could only wait in silence, fearing to provoke the lord in what seemed to be a momentous event.
"The Sign of Ainz Ooal Gown... but then that means-"
"Indeed," said the girl. Her cocky smile almost spoke to disrespect, were it not for the kindly warmth in her eyes. "The only one of its kind, as you'd said. The very same Sign you gave me, father."
"The Sign is still with me..." the master said to himself. "Then, there can only be one explanation... But tell me, how did you come to arrive here?"
"I traveled back the streams of time, aided by the will of Nazarick itself," said the girl. "And I came to ensure I would be born. That you would choose mother to be your," the girl's eyes shifted quickly to Albedo, "Only. Lawful. Loving. Wife."
The sound of intense grinding could be heard-coming from the Overseer's mouth. The look in her eyes almost made the maid faint.
Ainz-sama cleared his throat. "I see. Who, then, is this mother?"
A hopeful look could be seen on Albedo's face, for a moment.
The girl grinned. "You may know mother as Narberal Gamma, of the Pleiades."
"And then Albedo-sama..."
"No, never mind that," said Demiurge, halting the maid's discourse. "The rest of the events are plain to see."
Indeed, he had already deduced much of what had happened, based from what he'd observed of the throne room upon his arrival. He'd only needed confirmation about the source of the unrest, directly from someone who had been there.
There had been a great battle in the throne room, leaving scars and marks that might be permanent. A stern reminder of that Overseer's instability, and the arrival of that mysterious "Daughter" of Ainz-sama's.
Demiurge's lip curled into a small smile. Ainz-sama was currently in his own quarters, while Albedo had been personally restrained in confinement by some of his own minions, along with his lord's stern prohibition to stay there until she was summoned.
To have held her own against a Guardian-indeed there could be none who could claim that but the Master himself. Or, as it turned out, his spawn.
A strange sort of joy bloomed in Demiurge's heart. While the manner of arrival was far from ideal, there seemed to be no question that the girl was the Master's. The Master had claimed her himself.
Indeed, he'd far preferred if the person was a male, who would be capable of spreading his inheritance far better. But a female was fine. Queens were formidable in their own right-one need only look at Albedo to be convinced.
A lot of things to consider now, and a lot of things to revise. This person beyond the door may upset the balance in Nazarick, but Demiurge knew he could twist it to be in his lord's favor. Though his honored daughter had returned only via "time travel", it gave hope that somehow, someday, Ainz-sama could produce an heir that all of Nazarick could come to serve.
And so, he couldn't just let this invader get her way. Yes, Narberal Gamma was powerful, and certainly commendable for being handpicked by the Lord to accompany him in the outside world. But Demiurge could see into his Lord's heart, and could guess his desire to choose his mate freely. He should not be influenced by even his daughter, but should mate of his own free will.
Thinking such thoughts, Demiurge raised a hand to knock.
A flash of light.
A shrouded figure emerged from the mists. The alarm sounded, cueing the entire dungeon to the appearance of yet another intruder. Hordes of undead, triggered by the trap, came surging from the corridors around it.
"I can smell another one... Tch someone got here first."
The figure raised its weapon.
"Please wait, father. I shall certainly unite you with mother."
Shurpuff says: Just a little side fiction, to regurgitate odd concepts in-between chapters.
Anyway, the concept isn't terribly original, but I did my best. Even if it just took, like, thirty minutes to write.
Thanks for reading!
