Legend has it that beyond the Sky Realm's Thundercloud City, Rainfall Realm, Frost and Snow Plains, and Windstorm River lies a mysterious kingdom: Rainbow Heaven. It is the source of all the world's colors, and the most powerful nation in the Sky Realm. Since ancient times, each generation's heir has had a different background, but this generation was different. From the moment she was born, she was cursed by fate. Within her lay the power to protect the world or destroy everything. When she turned three hundred, she would ascend to immortality and face judgment. But she did not sit idly by as the years passed. She joined Hope Seekers and became a memory mage. She saved Qiaona, and Moxi, who belonged to a race opposed to her own. Six hundred years ago, an accident took her away from the Sky Realm. Six hundred years later, she was reborn as a human and returned here once more.
