The more powerful the spell, the more it depletes one's spirit.
Earlier, when Roy cast a curse on Theodore, she experienced symptoms of bleeding from the mouth and nose. After many days of meditation training, her mental resilience had strengthened significantly, and now she could finally successfully cast the Life-taking Spell.
However... her body was also near its limit.
Lying groggily for an unknown length of time, the pain in her body became dull and heavy. Later, a sharp stabbing pain surged in her left chest, her heart throbbing painfully. Something warm and soft brushed across her cheek, again and again.
This sensation gave Roy an illusion.
It was as if she had returned to her childhood, curled up on a large, empty bed. Mrs. Derek stood beside her, stroking her hair, speaking in a gentle yet detached tone.
You should sleep now... A bedtime story? It's not ladylike to tire and burden your mother.
