1 - Vision

Book #4: A year after Tadeas was found as the new Primary Archangel, the Oracle has received a vision implying Satiya, Husani, Ava and Tadeas must rescue a Draik and Angel from some humans, but doesn't say why all four are needed, just that it is urgent. The group ends up bouncing around the USH to find one threat, and a foreign country to defeat another. They will need all their strength to endure, alone.
