Isaac stood in the flesh-filled room. He donned a wide-brimmed Wizard Hat, letting the shadow fall across his face, then raised his hands high and shouted with fervent zeal, "O supreme Master, ruler of all the world's flesh! Your devout believer offers this sacrifice and begs for Your descent!"
"Ghk—"
The moment Isaac's words rang out, a bound Cultist in another corner of the castle went rigid. His eyes rolled back in his head, and a choked, gurgling sound escaped his lips.
Meanwhile, Isaac himself had taken on the aura of that very Cultist.
This was the Summoning Technique, a form of Magic originally used by Believers to channel Divine Power. It was later obtained by the Mad Witches, and with a few modifications, became an ability to temporarily alter one's identity in the eyes of a High-Position Existence. In other words, at this very moment, Isaac *was* that Cultist!
