  We report on a new class of flux vacua generically present in Calabi-Yau
compactifications of type-IIB string theory. At these vacua, the mass spectrum
of the complete axio-dilaton/complex structure sector is given, to leading
order in $\alpha'$ and $g_s$, by a simple analytic formula independent of the
choice of Calabi-Yau. We provide a method to find these vacua, and construct an
ensemble of $17,054$ solutions for the Calabi-Yau hypersurface
$\mathbb{WP}_{[1,1,1,6,9]}^4$, where the masses of the axio-dilaton and the
$272$ complex structure fields can be explicitly computed.
