Cassy then closed her eyes thinking of the soil that was essential to making things grow like plants, flowers, magic herbs, and then the ground on which she had sat down started to shake a little and the green flame then appeared in her mind.
The ground immediately stopped shaking and Cassy was surprised to see that her green flame was as steady as her yellow flame.

Once she appeared in her mind, she opened her hand and she focused on the green flame that appeared in her mind.
She could now feel the energy of her green flame and so 'she' or 'he' materialized in her hand without much effort from her.
