Omniscience

Declare a mythic astrological truth tied to a kingdom, prophecy, eclipse, bloodline, war, lost road, dead star, or impossible birth-chart. Define its principle with the GM: the prophecy no one can outrun, the star that names the heir, the chart that finds the hidden city, or the omen that ends a war. It can be opposed only by Tier 10 fate magic, divine intervention, absolute secrecy, or a story condition set when declared.
