Hierarch Asterios:
I apologize for putting such a heavy burden on your young shoulders, but it is your fate so you must deal with it.
You must find the Water of Life and save the Mother Tree! Finding the water will be a painful task that will require patience and sacrifice. I give you this amulet which contains the blessings of the Mother Tree guardians, keep it safe.
Thalia and her sisters know more than anyone else about the Water of Life. Take this letter and meet Thalia. You can find her in the eastern part of the Iris Lake.
