A different person
A pure white light appeared at the same time that the large-scale spell activated. It covered the entire army of the human race under the Celestial's protection. The bright light collided with the dark fire that had instantly turned the ground dark and the grasses dead. Even the birds that just happen to pass by above the battlefield fell to the ground with their bodies scorched black.
The generals together with their armies watched as the power of the Abyss collided with the power of the Celestials. They were not affected with the fire since Llewel could freely control the fire and focus only on his target. If you are his ally then you will not be harmed.
