The power of the dark supernova spread across the Emptiness, and its range was so large that it even crashed against the force field protecting the Ice-Fire World. Luckily most of its power had faded by then, or else it would have been extremely dangerous for the inhabitants of the world.
Zatiel's breathing was rough, and he was having difficulty regulating the energy inside his body and Inner Universe. The Thanatos Eye closed on its own, and the Eros Eye glowed, using its power to heal the internal damage.
That dark supernova was the culmination of the End Force under the control of the Samsara Thearch, and it required everything he had to unleash it. With the pupils holding the white sun and Samsara Force locked, it was one of Zatiel's strongest weapons.
If the Samsara Thearch ended up wounded by releasing such a powerful technique, then the state of the Ice Roc and Fire King could be expected.
