  Starting from the Hamiltonian formulation for the inhomogeneous Mixmaster
dynam- ics, we approach its quantum features through the link of the
quasi-classical limit. We fix the proper operator-ordering which ensures that
the WKB continuity equation overlaps the Liouville theorem as restricted to the
configuration space. We describe the full quantum dynamics of the model in some
details, providing a characterization of the (discrete) spectrum with analytic
expressions for the limit of high occupation number. One of the main
achievements of our analysis relies on the description of the ground state
morphology, showing how it is characterized by a non-vanishing zero-point
energy associated to the Universe anisotropy degrees of freedom
