The candle guttered in its brass holder, casting long shadows across Nathaniel Hale's study. Outside, the Thames fog pressed against the windowpanes like a living thing seeking entry.

Not prophecy in any traditional sense—no visions, no divine inspiration, no burning bushes. Just facts. Dates. Events. Causation chains so detailed they read like a historian's commentary written by someone who had actually lived through every moment.
