Since the brooch could only enhance ancient spells, Astrid found very few situations where it was actually useful. Moreover, casting just one high-level apprentice spell had already exhausted her mentally. On a battlefield, if she missed her target, it would likely mean her death.
Leaning back in her seat, letting her neck press against her long hair, Astrid looked up at the bright light above, feeling the chill from all around.
She gently kicked off her high heels, bent her knees, and tucked her black-stockinged feet together, curling up in the seat to preserve the precious warmth she had managed to retain.
This long-lost sense of exhaustion would affect both the mind and body, even making thinking unusually stiff.
Astrid closed her eyes and entered a meditative state. After ten minutes, the thin ice in the room began to melt on its own, and the temperature dropped again.
