Healers, like Thea, used their own energy for their craft. Warriors, like Shen, were born light-footed and charged by the sun. Tempests, like Banba, weaved their storms from a strand of wind and cast infernos from a single spark of lightning, and Seers turned to the night sky for their visions—an open space to watch the starcrest birds cast patterns of the future among the stars—though that craft was so rare, Wren had never even met a seer in person.
