Following the Great Conjunction, deities can be confronted and defeated in material combat as any other creature. Though embodied gods are extraordinarily powerful, they are also conceptually myopic, limited in their thought to ideas and plans consistent with their aspect, and often arrogant. They have the ability to, through covenants, grant boons to devotees and so are often served by fanatics. Bound gods retain their ability to grant power via covenants. Most clerics of bound gods seek primarily to free their patron.
When a god is defeated (reduced to zero hit points), the victor may either destroy the god and diminish the associated reality principle, collect the remnants as a deindividuated talisman that can be incorporated by another deity, or bind the god to service (though this requires magics known primarily by the Copernican Magisters). Bound gods can then be used to power Copernican devices or spells. However, bound gods remain sentient and wrathful, and until destroyed continue to be connected to any covenanted clerics (considered power thieves by Copernican law).
Given that no god is now safe from direct assault, many deities also scheme against each other, seeking to become sole claimants to ideal offices. In this way, for example, Zeus may seek to defeat and incorporate reality principles currently presided over by Thor, since they both claim the endless principle of Thunder. Gods of opposed concepts, such as darkness and light, also are often at odds.
