When Aiden and the three Great Witches were playing chess, the Great Witches had once suspected that Aiden had been subjected to a suggestion, a kind of suggestion that disrupts cognition—
Abigail, "Could it be that you've been under some kind of suggestion, like... a trap that triggers once certain conditions are met."
Qiqimora, "There's also a possibility that the suggestion just changes a specific cognition, one that could mislead you until you gain authority."
Lamia, "But after being promoted to ruler, such a suggestion might also be broken. It's meaningless, right, kid?"
Aiden was also quite certain that his Spirit had been tampered with by the Conspiracy Goddess, those sealed memories, and the erased dialogue between the former Aiden and the Conspiracy Goddess, all indicated this fact.
And once Aiden obtained authority, he became a ruler, and he had the power to counter the tampering done by the Conspiracy Goddess.
