Although Cain asked the question, he did not expect an answer from Ao, as he knew the World Will had no idea why that dream illusion was put in place and seemed to have no control over it. Thanks to his willpower, he was able to focus, and soon Cain's eyes grew sharp as he remembered Horus's words.
"If the dream illusion was spread across all worlds in the World Forge, then everybody who rose from them would bring a sense of animosity and racial hatred in their souls as they march into the Nine Empyrean Suns Universe." Cain could not help but clench his fists, thinking how a xenophobic universe would think of a world like Aether, where all Sacred Races were in harmony.
'They will loathe us; everybody will hate our guts and see us as an aberration that must be eliminated.' It was not hard to come to an idea of what might happen, and Cain's eyes turned eerily cold.
