Abstract: Controlled de Sitter vacua -- if they exist -- are hiding in difficult regions of the string Landscape. They seem to require such an intricate interplay of ingredients, that many things can go wrong and invalidate the solutions (in fact, checking their validity with explicit computations is usually a difficult task in itself). With this in mind, one might explore a combination of ingredients that are both common and simple enough to be computed explicitly: Riemann flat manifolds, fluxes and Casimir energies. I will discuss whether these could in principle provide de Sitter vacua and highlight how one can explicitly compute each step in these constructions, as well as how one might hope to exploit the Riemann flat manifold symmetries in order to enhance the Casimir contribution.
