Damage Control
The demonic empress, Gantamo, was gone. It was unlikely that Bardeelus killed her, especially since he didn't reap her soul, but the damage he did was still plentiful.
The world rumbled around them for half a minute, which meant that he humbled that demon at the very least. He didn't know how tightly this demon was connected to this world, and neither did he have the energy to mutter it over right now. Too many things went on at the same time, and he'd rather focus on the things that were present and important.
"Don't leave Audera out of your sight," Bardeelus said, referring to the whole team.
Afterwards, he wiped some blood off of his face, ignored the five corpses in front of him, and squatted near the black, one-foot wide pyramid.
It was on top of the forty-or-so, sapphire gems! He had to scratch some blood off of his eyes as well, just to get a better look at it.
