The Holy Priestess knew that the reason she had been able to survive the pursuit of the false Priestess was because of the Holy Spirit.
After the false Priestess was slain, it was this soul that had managed to recover even more, and helped her further. Having the soul of a goddess with her was no different than always having a god with her.
She didn't just get the blessings of the goddess, but also managed to learn many skills that she couldn't have learned otherwise. Through the goddess, she had learned knowledge that someone like her should never have possessed.
The goddess's soul was not only her biggest supporter but also the reason she was still alive. If she gave up on the goddess, she was going to lose everything.
Even though she had acted in good faith to save the people of this continent, deep down, she was greedy for power herself. She wanted what belonged to her, which was taken by the false Priestess.
