One one side were the busy squadrons of Bright Sorcerers operating under the Battle Command, carrying out combat deployment.
An army group of Soul Slaves, under the Bright Sorcerer military command flooded into the entrance of the Burrow World like water being let loose out of a dam.
On the other side were three hundred or more Elite Dark Sorcerers that followed closely by Black Isotta's side, awaiting his further orders.
Crash, crash, crash…
The space surrounding him kept on collapsing into itself, and the air further away from him contorted into abstract shapes. Due to the chaotic spatial core of the Black Isotta, his silhouette remained a blurred figure. One could barely see his black robes and the massive book he carried on his back through the spatial distortion around him.
As such, it was not uncommon for the Demon-Hunter Sorcerers that first encountered Black Isotta to hold their breaths in surprise at the out-of-this-world sight.
