Abstract: We discuss interrelations between several ideas in quantum gravity. One is the Swampland program, which states that a low-energy effective field theory should satisfy non-trivial constraints to have an ultraviolet (UV) completion in quantum gravity. Another is the concept of ensemble averaging in holography, where a coarse-grained description is obtained by an integral over a moduli space. To examine the relation between the two, we study ensemble averages of generalized Narain-type theories associated with a general even quadratic form and their holographic duals. We establish the emergence of global symmetries and discuss their consistency with the Swampland conjecture forbidding exact global symmetries. Out of all the zero-form symmetries, the quantum symmetries in the bulk are truly emergent, while classical symmetries are identified as vestiges of T-duality of the Narain-type theories. The latter mechanism can be formulated very generally as a ``folding'' of T-duality orbits via the Siegel-Weil Theorem. We also discuss the interrelations between the Swampland distance conjecture, on one hand, and ensemble averaging and spectral decompositions, on the other. The spectral decomposition also illustrates how ensemble averaging sits within the low-energy limit of certain string compactifications. Our analysis suggests fascinating links between the Swampland, the Landscape, and ensemble averaging.
