Uroy is a member of Behemdolg army.

Apparently, he had a high position commanding several soldiers, when they were afraid of going into battle, Uroy would show them his blessing to create and manipulate flames, claiming to be one chosen by god, his king, and that he would use his power to defeat the enemies.

Orphaned siblings Agni and Luna, like the Ice Witch who cursed their world, are two of the “blessed,” humans who hold special abilities. However, not all who are blessed are friendly, and after another of their kind attacks Agni and decimates the orphans' village, Agni fights to survive, vowing revenge.
