The Great Work

Declare a mythic transmutation tied to a kingdom, curse, body, plague, wasteland, artifact-forge, impossible bridge, living statue, or ruined city. Define its principle with the GM: turn a battlefield to glass, make a city breathe underwater, restore a petrified people, unmake a tyrant’s fortress, or complete the impossible alchemical work. It can be opposed only by Tier 10 transmutation, divine intervention, or a story condition set when declared.
