After Corey stored the Shard of Heaven's Fury in his Tri-Pupil Eyes, he performed an inspection of his body just to make sure everything was good.
He didn't need to do that, but he just did it out of pure curiosity.
He slowly got to his feet, rotated his shoulders, turned his neck, and his upper body to 'remove' every bit of stiffness in his body.
Once again, he had no need for all of these, but he did them all to briefly reminisce about his life before the apocalypse.
As he was doing all sorts of warm up exercises while inspecting his body, he frowned.
He noticed that his aura and presence had become... more terrifying.
He did not give off the feeling of being a Mystic Being, but at the same time, he gave off the feeling of being something... otherworldly.
His aura had always been like this, but he had been able to control it and hide it.
This time around, he could not do it the normal way because his aura had... more weight.
