Warehouse Chief Natools:
I do not know its location, but they have requested that they be allowed to consult something called the Sealed Prophecy - Path of the God.
Your predecessor obtained this document, and they undoubtedly believe that it contains clues about the angel's whereabouts.
You will be able to obtain the angel's message using a unique Echo Crystal that can store sound.
If you have more questions, ask Grand Master Tobias in the town of Gludio.
Take the Sealed Prophecy - Path of the God with you.
