The Lodesoul Theorem is a controversial multiversal cosmological theory proposing the existence of singular individuals whose existence serves as a structural constant within reality itself. These individuals are designated Lodesouls — entities whose presence stabilizes, defines, or influences the trajectory of their native universe.
The theorem challenges the long-held metaphysical assumption that all sentient beings possess equivalent existential weight. Instead, it suggests that certain individuals function as narrative and structural keystones whose continuity directly affects universal cohesion.
