Prayer of Purification.

From almost the numerous novels Myrene has read back then, not only to the book that this world was written of. That skill was a very popular skill that only the Saintess that would accompany the chosen hero that would kill the demon king could wield. It was a blessing from the goddess of light the moment she was already born. 

From the Chaos Arise, the novel to which this world belongs, the chosen Saintess would be the Princess of the Myrtle Kingdom. From the story and excerpt of the novel, when the two royal couple was not able to conceive a royal heir, a woman shrouded in white appeared, telling them that she was the priestess sent by the goddess. And thus she suggested for the royal couple pray for an entire year without missing a single day to conceive a child.
