He discussed the prophecies that he had seen with his grandmother some more. It was interesting that his grandmother did not see everything he had seen. Apparently, when it came to delivering prophecies to another person, she used her Martial Embodiment so that the prophecy would be built from both her and her target's subconsciousness.
