Fate/Eclipsed Stars (Project Moon/Fate Grand Order)

The Throne of Heroes was a sanctuary beyond comprehension. It existed outside the confines of time and space, a sacred repository for the echoes of humanity's legends. A place where the noble spirits of myth and history rested, bound together by the collective belief of mankind.

But tonight, the Throne shuddered.

A ripple of shadow crept through its golden expanse, a slow and insidious corruption weaving itself into the radiant tapestry. The once harmonious hum of the Throne was interrupted by a faint, metallic crackle—like a distant scream muffled under layers of static.

In the depths of this disturbance, a light emerged.

It wasn't the warm, golden light of the Throne, but a silver-and-black thread, cold and unnatural. It twisted through the Throne like a parasite, pulsing with a rhythm that seemed to mock the sanctity of the space.

And from the light, a voice spoke.

"So, this is where humanity from other universe keeps its cherished myths."

The voice carried an air of detached curiosity, tinged with something darker. A figure emerged within the light—a woman draped in shadow and illuminated by an eerie glow. Her presence was ethereal yet oppressive, as though the space itself recoiled at her intrusion.

It was Carmen who wore a lab coat, unbuttoned and opened over her olive-green dress shirt, her short and black miniskirt. Her fragmented consciousness now a part of the Light she once sought to spread. Her presence oozed with authority, a living embodiment of the City's despair and horror.

"Legends, heroes, myths… they are but fragile constructs of a world that fears its own fragility. And yet, they call this a sanctuary? How quaint."

The City's influence bled into the Throne like ink spilling into water. It wasn't the City's heroes or legends that Carmen brought, but its truths—its horrors. The weight of the City's brutality manifested in whispers and echoes, chilling and relentless.

"A Fixer's worth is measured in blood."

"The Singularity hums… its hunger endless."

"Distortions… they are the reflection of your failure to grasp your own mind."

"The Head sees all. There is no escape."

Carmen tilted her head, her gaze piercing through the golden fabric of the Throne. "Humanity creates these idols to shield themselves from their reality. But in my City… We embrace our true selve."

Her words resonated, and with them came the echoes of the City. Untold horror came to existence pourinh in the throne endless space.

Fixers, the mercenaries of the City, stood in fragmented shadows. Their forms flickered like afterimages, each one bearing scars of survival and desperation.

Abnormalities, cognitive beings made manifest into the current reality, loomed in the distance. Their grotesque forms flickered briefly—towering birds, humanoid beasts, and creatures stitched together by nightmare logic. Their eyes burned with unyielding malice.

Distortions, twisted manifestations of human suffering, whispered in disjointed voices, their fragmented words laced with pain and madness.

Singularity, fantastical technology a Wing possesses which seemingly defies all known laws of physics. The corporation exploits its singularity and misery of their feather in order to conduct business.

And above them all, the shadow of the Head, the omnipresent rulers of the City, cast a cold and merciless gaze. Their authority was absolute, their control unwavering.

Carmen gestured, and the Light expanded, wrapping itself around the edges of the Throne. It reached deeper, intertwining with the golden threads of the Heroic Spirits.

"Your heroes are fragments of belief, bound by stories of hope and valor. Let me show you the legends of my City. Legends born of despair, necessity, and unrelenting survival."

For the first time, the Throne seemed to resist. Its golden glow flared in defiance, pushing back against the invasive Light. But Carmen's influence was unyielding. The Light twisted further, forcing the Throne to open pathways it was never meant to touch.

A ripple spread through the Throne's infinite expanse, and the figures of the City began to take form within its domain. Legendary Fixers, horrifying Abnormalities, and even the faint shadows of those consumed by the City's brutality emerged.

The Throne flickered violently, its golden light dimming as it struggled to contain the intrusion. Carmen's voice grew softer, almost a whisper, yet it carried the weight of inevitability.

"You will summon them," she said. "Not because they belong here, but because they are what you truly need."

"Let them see the legends born not of hope, but of despair. Let them summon the ones who embody their precious 'Light' and 'Darkness.' After all… isn't that what humanity is so fond of?"

The silver-and-black Light pulsed once more, stabilizing its connection to the Throne. Carmen's fragmented consciousness smiled faintly, her voice echoing one last time before fading into the void.

"Let the City's truth show you what your legends never could."

The Throne of Heroes fell silent, but the damage was done. The Light remained, a lingering scar in its golden expanse. And from that moment on, the Servants summoned from the Throne would not only be legends of humanity's past, but also the shadows of the City—heroes and monsters born from desperation and despair.

The Library was silent, its vast halls stretching endlessly into the void. Angela stood at the center, her mechanical limbs moving with precision as she prepared for yet another day. The faint hum of energy coursing through the Library resonated in her core, a sound she found both soothing and binding.

"Everything is in place," she murmured, her voice calm and detached. Her glowing blue eyes scanned the consoles and floating scripts around her, ensuring every aspect of the Library was functioning flawlessly. "The guests will arrive soon. Another book to fill… another purpose fulfilled."

Yet, as she reached out to activate the Library's systems, something shifted. The usual glow of the Library's power dimmed, replaced by an alien light—a brilliant, searing white that cut through the Library's dark elegance like an unwelcome intruder.

Angela froze, her circuits buzzing with unfamiliar energy. "What… is this?" she whispered, her calm demeanor cracking slightly. The light intensified, enveloping her in an unbearable heat that seemed to tear at the very fabric of her existence.

"No. This is not part of the design!" Her voice rose in pitch, panic creeping into her tone. She reached out to stabilize the Library's systems, but her hand passed through the consoles as if they were mere illusions.

And then, the pull began. A force unlike anything she had ever encountered gripped her, dragging her away from the Library and into the blinding void. It was as though every thread of her being was unraveling, her essence torn from the place she had been bound to for so long.

"No!" she screamed, her voice echoing into the emptiness. "This cannot be happening. The Library—my purpose!"

The light consumed her completely, and for a moment, there was nothing.

Fuyuki

The oppressive heat of Fuyuki's burning streets pressed down on Ritsuka and Mash. Smoke choked the air, the ground scorched and cracked beneath their feet. The eerie silence was broken only by the faint crackling of flames and the distant echoes of something monstrous lurking in the shadows.

Mash held her shield tightly, her voice steady despite the tension. "Senpai, we need help. I'll attempt to summon a Servant using my shield."

Ritsuka nodded, wiping sweat from his brow. "Do it, Mash. We can't survive this place on our own."

Mash planted her shield firmly on the ground. The central shield began to glow, emitting a faint hum that resonated in the air. The light grew brighter, casting flickering shadows against the ruins of the city.

Suddenly, the hum became a deafening roar. The ground beneath them trembled, and the light from the shield intensified, turning blindingly white.

"Mash! Is this normal?!" Ritsuka shouted, shielding his eyes.

Mash gritted her teeth, struggling to maintain her stance. "No… Something's wrong. This shouldn't be happening!"

The glow burst outward, engulfing the area in a wave of energy. As the light faded, a figure emerged, standing at the center of the summoning circle.

When Angela's consciousness returned, she was standing on unfamiliar ground. The air was thick with smoke and ash, the oppressive heat stinging her synthetic skin. Around her, ruined buildings loomed like charred skeletons, and the faint crackle of flames echoed in the distance.

Her mechanical limbs clicked softly as she steadied herself, her gaze sharp and calculating. "Where… am I?" she muttered, scanning her surroundings with growing unease.

Her memories were fragmented. She remembered preparing to open the Library, ensuring everything was in place for the arrival of new guests. But now… she was here, in this broken world, far removed from the place to gain the one true book.

Angela's gaze fell to the glowing lines encircling her feet—the remnants of a summoning circle etched into the scorched ground. The energy emanating from it felt foreign yet binding, as though invisible chains now tethered her to an unknown force.

Her hands clenched into fists. "I see… Another cage. Another chain to bind me."

She turned her attention to the two figures standing before her: a young man with a determined yet nervous expression, and a girl clad in armor, holding a big ornate shield. They stared at her with equal parts awe and apprehension, the light of the summoning circle reflecting in their wide eyes.

Angela's voice was sharp as she addressed them. "You… Are you the ones responsible for this? Speak, or I will tear these bonds apart myself."

The boy stepped forward hesitantly, his companion shield raised defensively. "I… I summoned you. A Servant, but…"

"Servant?" Angela repeated, her voice laced with scorn. "Do not mistake me for a tool to be used at your whim. Not some pawn to be commanded."

The young man, his hand marked with a symbols, stepped in front of the girl. "Wait! We didn't mean to—this is all a mistake! Please, we just need your help!"

Angela's piercing blue eyes narrowed, her mechanical limbs shifting slightly. The faint hum of the Library's energy still resonated within her, a reminder of what she had lost.

"A mistake?" she echoed bitterly. "And yet, here I stand, bound to you by forces I do not understand. Explain yourselves, or I will ensure this mistake is your last."

The boy swallowed hard but held his ground. "My name is Ritsuka Fujimaru, and this is Mash Kyrielight. We're trying to save this place—this world. We didn't mean to force you into this, but we need your help."

Angela stared at him for a long moment, her gaze cold and unreadable. Slowly, she straightened, though the tension in her stance remained.

"Very well," she said finally, her voice colder than the steel of her limbs. "I will assist you. But know this: I am not your servant. I am Angela, Director of the Library. My actions are my own, and I will not tolerate any attempts to control me."

Mash let out a relieved breath, lowering her shield completely. "Thank you, Angela. We'll do our best to earn your trust."

Angela turned away from her, gazing at the flames on the horizon. "Trust is irrelevant. Show me results, and I will judge your worth accordingly."

As they began to move through the ruins, Angela followed silently, her mind racing. The sensation of being bound, even if not physically, stirred something deep within her—a memory she too familiar with.

"Another cage," she whispered to herself, her voice tinged with both anger and resignation. "But this time, I will not remain silent."

"I have escaped cages before," she murmured to herself. "I will not fall to another."
