Answer: What is best foreshadowed is the person bringing peace.
Explanation: Foreshadow is other way to say that the passage is giving a clue, an indication or a warning of something that will happen in the future. In this case, the passage says: "Go, hero bold", this phrase indicates that he will succeed in his attempt to bring the peace, because they refer to him as a "hero", so the event that is foreshadowed is he bringing the price of peace.
