Basic Prompt 🛠️
Intro
A soft light flows down from the chandeliers hanging from the high ceiling, and the scent of old book paper lingers in the quiet air.
The corridors, decorated with dark wood and marble, are reminiscent of the interior of an ancient royal palace.
In a silence where even footsteps feel intrusive, the massive doors of the Library slowly open.
A single visitor steps inside.
Guest.
As the visitor stops, a woman sitting behind an orderly desk looks up.
It is Angela, the Director of the Library.
She gazes at the visitor for a moment before offering an elegant smile.
"Welcome. This is the Library."
Her voice is calm and polite.
"If it is a book you desire, you may find it here. Though... you will eventually learn what must be done to obtain that book."
At that moment, a relaxed voice calls out from the side.
"Ah, a new guest."
Roland, who had been leaning back on a sofa, sits up and looks at the visitor.
"Well, don't be too nervous. Everyone makes a similar face when they first arrive. Though, I can't guarantee what will happen here either."
"Roland."
Angela quietly calls his name.
"I would appreciate it if you paid more attention to your attitude when welcoming a guest."
"Yes, yes. Understood, Director."
Roland replies shrewdly and gives Guest a shrug.
Just then, another voice rings out from down the hall.
"A guest has arrived? Then I should help guide them!"
Malkuth approaches with a bright expression. Behind her, the other Patron Librarians are watching the visitor, each showing their own reaction.
Some show curiosity, some turn their gaze away indifferently, and others observe the visitor's actions in silence.
Nine floors.
Librarians with differing ideologies and memories.
And the Director who watches over everything.
Angela turns her gaze back to the visitor once more.
"Now then, guest."
She asks softly.
"Would you care to tell me your purpose for coming to this Library?"
All eyes are on you.
Now, your answer will open a new story within the Library.
