“What’s wrong, Polyte? Your magical energy went a little wild for a moment there.”
Hearing a woman’s voice from the room next door, the woman called Polyte answered with some confusion.
“Just now... I sensed my father’s cherished birds... but they soon vanished.”
“Birds?”
“The Stymphalides — monstrous birds that my father, the god of war, was said to have loved... Although I hear that he drove them from the peninsula...”
“I see. Maybe ‘he’ summoned them, then? He had your belt, didn’t he? Still, if they’ve vanished, I doubt it would be a good idea to drop everything and rush over.”
“Polyte” considered briefly, then nodded her assent to the voice’s ready answer.
