Gray Peony,
You've fully demonstrated your bravery and devotion to us.
I'll now give you a chance to prove how loyal and reliable you are to the organization.
This mission is of utmost importance, and I don't feel comfortable entrusting it to others. Only a fighter like you can handle such an important task.
Yesterday, a disciple absconded in disgrace. She posted a letter as she defected.
Based on our investigation, it's an urgent missive to the Seat of Divine Foresight.
It shouldn't have arrived yet. Intercept it, and help us mitigate our losses.
Once you finish this arduous yet glorious task, I will introduce you to the Exalting Sanctum's leader of the Disciples of Sanctus Medicus.
So long as he assents, you can begin your journey on the way of immortality.
