Fran glanced at the mages being dragged out of the Forest Array by the Guardians and sighed silently.
"William's Illusion Magic Array uses the human heart," he said.
Everyone responds differently, leading to completely different outcomes.
The darker the heart, the more extreme the reactions and the more terrifying the things seen.
Being selfish is fine, but if you harm others without benefiting yourself, you might come face to face with the Evil God.
Adrian hadn't seen it, but Fran heard William describe it as a legend from their world.
Fran wondered what the people of that world were thinking, to conjure up such revolting things; he felt it was best not to see any of it with his own eyes.
Perhaps the God of Smithing saw the most disgusting version of it; otherwise, given the extent of his evil, how could he have been scared?
