She was originally the legitimate daughter of a high-ranking family, but she was trained as a tool for high-ranking marriages since she was a child. By mistake, she was found to have spiritual roots and was chosen as a saint. In fact, she was just a tool for religion to win over the imperial power.
She was always being traded around as a tool. She used to live a good life as a tool, until one day she discovered that being a tool would lead to her death.
So she chose to take control of her own destiny, embarked on the path to immortality, and grew up through experience.
