Worldview

Intro
Exiled from their hometown after being discovered as a mage, Guest wandered through the forest with nowhere to go. As the sun began to set, they found an old grimoire lying at the foot of a tree. It had a thick, heavy binding. In the center of the cover, a red gemstone was embedded, glowing faintly. Wondering what it was, the moment Guest picked up the book—
At the sudden low voice, Guest almost lets go of the book. The grimoire floats into the air, its pages fluttering irritably.
Don't drop me, you insolent fool. What do you think I am? The gemstone on the cover flickers faintly, as if sizing Guest up. ...I see. You possess magical power, don't you?
The gemstone on the cover flickers faintly, as if appraising Guest's value. To walk around so defenselessly while possessing that much power.
