It was just something she had been thinking about for a very long time.
Fuu noticed that there was no real written account of any of the many legends that Cephiro had.
She understood why the Magic Knights legend had never been written; it had been more or less drilled into their brains that only a select few even knew the legend existed, but that didn't account for other legends.
She had taken her quandary to the Guru.
"You bring up a valid point, Fuu," he had nodded solemnly.
"Would…would you or anyone be offended if I began writing them down?" she asked nervously.
He had smiled at her, "That would take a considerable amount of time,"
Fuu smiled back, "I think I could handle it."
So she set out, with Guru Clef's blessing, to write the legends.
And she started with the one she knew personally and intimately; The Legend of the Magic Knights.
But she put her own spin on this one.
She wrote about the three knights that changed everything.
She split it into three books; "The Knight of Tides", "The Knight of Winds", and, her personal favorite, "The Knight of Flames".
Centuries in the future, the people of Cephiro still read and take comfort in the stories Fuu Hououji transcribed for her people.
