Magnetic monopole as a spacetime defect

We propose that the only possible realization of a magnetic pole is emergent, it being an artifact torsion defect in curved spacetime. This special phase built upon class degenerate metric spacetime solutions first-order gravity vacuum. The (apparent) charge shown to have topological origin, given by lower-dimensional counterpart Nieh-Yan invariant. At invertible at distance, this gets reflected as (magnetic) Reissner-Nordstr\"om asymptotic observer, even though monopole itself remains hidden.
