Shrieeeek!
Suddenly, a horde of demonic shadow beasts swallowed the sky as tens of new spatial doorways formed. It was as if nighttime had abruptly descended over Siren's main headquarters.
As the horde of creatures closed in on Empyrean from every direction, he employed Sky Culling, bursting through the encirclement. A wind stream flowed around Empyrean and forced the demonic shadow beasts that attempted to obstruct his path back.
After breaking through the crowd of demonic shadow beasts, Empyrean headed straight for Aurelianus. Since the mirror in their hands was capable of interrupting his magic, Empyrean planned to destroy the object with physical means. But, Empyrean did not make it halfway to Aurelianus before the edge of a blade appeared near his right shoulder just a hair's width away.
