One and only one

Arthur's Extreme Nothingness collided with the man's temporal beam in a clash of raw, volatile power. The man poured more energy into his attack, attempting to overpower Arthur, but the balance quickly tipped against him. 

Clicking his tongue in frustration, the man forcefully detonated his temporal energy. The explosion offset Arthur's Extreme Nothingness, unleashing a shockwave that sent both Evan and Beatrix who tried to attack from his flanks hurtling away. 

Arthur, sensing the imminent danger to his Bounded Field, instantly dispelled it to avoid a catastrophic backlash that could wound him.

But, doing so inadvertently freed the man from its confines. 

The violent collision of temporal energies caused a flux in the surrounding time laws. The chaotic energy rippled outward, slamming into both Arthur and the man.
