In the vast expanse of Antarctica, a magnificent structure rises from the ground—a majestic semicircular fortress, ingeniously embedded into the embrace of the mountains like something from another world, gazing down upon this eternal whiteness.
This is the supreme sanctuary guarded by human reason—Chaldea, also known as the Phoenix Nest. A mystical workshop that transcends the mundane world, hidden from ordinary sight, it exists beyond all worldly power and constraints.
Here, elites from every field gather like a brilliant galaxy, where wisdom and magic collide at the ultimate level, and science and mystery perfectly merge.
All the giants of magic and science have formed a sacred alliance here, vowing to protect the long and glorious history of humankind, preventing it from turning to dust.
Yet, at this very moment—
A sharp, urgent cry shattered the brief silence like thunder—
"Dr. Lev, the end of humanity's future is approaching at an immeasurable speed!"
"The shadow of destruction is rapidly enveloping the entire world..."
Director Olga Marie stared at Lev, her eyes flashing with unprecedented fear and determination.
The apocalypse—the catastrophe that overturns all great civilizations—is approaching so suddenly, as if it will devour everything!
Even as a director bearing heavy responsibilities, Olga Marie could not help but feel tumultuous emotions surging within her heart...
"Fear not. We swear to rewrite the fate of humanity."
Dr. Lev's expression was cold as iron, yet his words carried an almost fanatical determination and persistence.
Romani Archiman, who had been silently observing from the side, wore an indescribably complex expression, though it soon returned to calm. He murmured softly, as if speaking to himself:
"Why did the light of civilization vanish? What kind of conspiracy lies behind this?"
Just as the three fell into deep thought simultaneously, the entirety of Chaldea seemed to tremble—
Ding—
A massive screen suddenly appeared in the sky, capturing the attention of everyone in Chaldea...
"Director... Dr. Romani Archiman..."
"A huge... screen has appeared in the sky?!"
"..."
"Senpai..." Mash was stunned, seemingly unable to believe the scene before her eyes...
"Could it be..."
A trace of gloom flickered across Director Olga Marie's pale face...
Could this truly be the final moment—the long-standing light of civilization completely extinguished?
It happened faster than anyone had anticipated...
So fast that...
Everything was thrown into chaos, and all previous countermeasures were rendered useless...
Dr. Lev, who also felt powerless, furrowed his brows in disappointment...
But soon—
Mash, who had been staring intently at the screen, gradually noticed clues!
"Everyone, look!"
"There are words on the screen!"
"..."
Everyone looked up and saw lines of text appearing on the screen.
And the same scene...
Centered around Chaldea, it spread in all directions—reaching countless Type-Moon worlds across different times and dimensions...
...
Timeline of the Fifth Holy Grail War:
"In the sky!"
A blue-eyed girl wearing a red sweater with twin ponytails momentarily spaced out before focusing on the scene before her...
This...
Was completely beyond the knowledge of magecraft she had mastered...
It was not part of the Holy Grail War...
Could it be...
At the same moment, Emiya Shirou, who was practicing pole vaulting, also muttered in surprise:
"Why has a huge screen appeared in the sky?"
Simultaneously—
Timeline of the Fourth Holy Grail War...
The World of Kara no Kyoukai...
The Timeline of Tsukihime...
In countless Type-Moon worlds, this massive screen suddenly appeared in everyone's sight like an enigma!
Touko Aozaki and Aoko Aozaki were in the middle of a conversation but were also drawn by the movement in the sky. They looked up simultaneously to see a massive screen materializing out of thin air.
"What in the world is that?" Aoko Aozaki frowned slightly...
Unperceivable!
A sense of the unknown enveloped everything like air...
Her sister, Touko, also gazed at the screen with a serious expression.
"This doesn't seem like magecraft, and there's no magical energy fluctuation... It shouldn't be sorcery either."
"But—"
Touko Aozaki pondered for a moment:
"Although the origin of this screen is unknown, at the very least... it appears harmless."
"..."
Yet—
Another question arose...
In the same timeline of Kara no Kyoukai, Shiki Ryogi slightly raised her head...
If this is neither magecraft nor sorcery, then what is it?
A sense of unease, as if the world were collapsing, filled Shiki Ryougi's heart...
...
Ding—
Accompanied by the sound of a metallic prompt...
Under the gazes of all Type-Moon worlds—filled with vigilance, curiosity, confusion, or hope, and countless other complex emotions—
A line of text began to appear synchronously on the massive screen:
[The Ten Virtues of the Type-Moon World—No. 10: Justice!]
