Just got my copy of Celestial Realms - one thing to note, from the short story at the start of one of the chapters:
Lady Moshi ascended the final steps of the path leading to the Shrine of the Lady Sun. At the top, she lit incense and placed it in an offering bowl at the statue’s feet, the scent of orange and clove filling the air. She reached into her robes, producing a piece of paper, and folded it expertly as she spoke.
“Mother Sun, you knew me before I knew myself…” Lady Moshi smiled. It was true that when her parents had been under the mistaken belief that they had a son, it had taken them all by surprise when Amaterasu began to speak to her. “…and so I have come to you for guidance. I can sense an imbalance in the world, within the elements themselves.” She frowned, staring down at the origami flower she had made.
Suddenly, flame surrounded the paper flower, crumbling the delicate petals and filling Lady Moshi’s unscorched hands with ash. She was overcome with a vision, images captured in the dancing fire.
She stood, ash swirling around her. Her goddess had given her a duty, and she would not fail her.
So the Centipede clan are explicitely aware of the Elemental Imbalance, and Moshi Chiasa, the Clan Champion, has been given some sort of instructions on what she needs to do about it.
