We consider issues of moduli stabilization and "area codes" for type II fluxcompactifications, and the "Inverse Problem" and "Fake Superpotentials" forextremal (non)supersymmetric black holes in type II compactifications on(orientifold of) a compact two-parameter Calabi-Yau expressed as a degree-18hypersurface in WCP^4[1,1,1,6,9] which has multiple singular loci in its modulispace. We argue the existence of extended "area codes" [1] wherein for the sameset of large NS-NS and RR fluxes, one can stabilize all the complex structuremoduli and the axion-dilaton modulus (to different sets of values) for pointsin the moduli space away as well as near the different singular conifold locileading to the existence of domain walls. Using techniques of [3] we explicitlyshow that given a set of moduli and choice of a gauge(the superpotential)corresponding to an extremal black hole, one can actually work out thecorresponding charges (of the extremal black hole) - the so-called "inverseproblem". We also show the existence of "fake superpotentials" [4]corresponding to non-BPS extremal black-hole solutions corresponding to theaforementioned Calabi-Yau three-fold. By including non-perturbative alpha' andinstanton corrections in the Kaehler potential and superpotential [2], we showthe possibility of getting a large-volume non-supersymmetric (A)dS minimum - adS minimum without the addition of anti-D3 branes a la KKLT. The chosenCalabi-Yau has been of relevance also from the point of other studies ofstabilization of the Kaehler moduli via nonperturbative instanton contributions[5] and the possibility of getting non-supersymmetric AdS vacua (and theirsubsequent dS-uplifts) using (alpha')^3 corrections to the Kaehler potential[6,7,8].
