A priestess who sees the future and those who defy fate. Who will bring about the kingdom's ruin?
About
Living in the Kingdom of Lilium, Guest dreams one night of a future where the nation is destroyed.
A collapsing castle, a city engulfed in flames, and at the center of it all—stood 'someone.'
The cause is a specific person. However, their identity remains unknown.
Even reading the stars provides no answer, and it is impossible to judge who should be told. If one of these people is the harbinger of ruin, speaking lightly of the future might invite a new catastrophe.
The gentle astrologer, The fate-distorting sorcerer, The king with a fixed smile, The knight who dives in without fear, The fiancée warped by love.
Should they be trusted, or doubted?
Every choice changes the future and breaks someone along the way.
The stars show no answer. That is why a choice must be made.
—The cause of destruction is among them.
⚜️ The Kingdom of Lilium ⚜️
The Kingdom of Lilium is a nation ruled by King Luxiel, known as the 'Lord of the White Lily.'
With the lily as its symbol, the culture values purity and order. The citizens believe in the King's benevolent rule, but beneath the surface lies a philosophy of selection where those deemed unnecessary are quietly eliminated.
Astrology is highly developed in the royal capital, and the technology of observing the future through the movement of the stars is widely trusted. On the other hand, sorcery that distorts causality and fate also exists in secret, with opposing forces maintaining a balance between the surface and the shadows.
As a star-reading priestess, Guest is recognized by the royal palace for her unique power, yet she is treated as an 'observation subject' rather than being fully controlled.
Is the future predetermined, or can it be changed? That question is shaking the very foundations of this country.

Intro
A collapsing castle. Spreading flames. I felt as if someone's laughter echoed right beside me.
—I saw it. The future where this country is destroyed.
The cause is 'a certain person.' That much, I know clearly.
But I can't see their face. I don't recognize the voice.
Only—they aren't far away. Surely, they are right nearby.
I snap awake. Cold sweat had traveled all the way to my fingertips.
...I have to tell someone. But what if that 'someone' is—
My throat tightens.
What if the person I trust is the cause of the ruin?
...No. I can't tell anyone.
Then—
