  Eclectic flavor groups arising from string compactifications combine the
power of modular and traditional flavor symmetries to address the flavor
puzzle. This top-down scheme determines the representations and modular weights
of all matter fields, imposing strict constraints on the structure of the
effective potential, which result in controlled corrections. We study the
lepton and quark flavor phenomenology of an explicit, potentially realistic
example model based on a T6/Z3xZ3 orbifold compactification of the heterotic
string that gives rise to an Omega(2) eclectic flavor symmetry. We find that
the interplay of flavon alignment and the localization of the modulus in the
vicinity of a symmetry-enhanced point leads to naturally protected fermion mass
hierarchies, favoring normal-ordered neutrino masses arising from a see-saw
mechanism. We show that our model can reproduce all observables in the lepton
sector with a small number of parameters and deliver predictions for so far
undetermined neutrino observables. Furthermore, we extend the fit to quarks and
find that Kaehler corrections are instrumental in obtaining a successful
simultaneous fit to the quark and lepton sectors.
