I will study the sequestering of blow-up fields through a CFT in a toroidal orbifold setting. In particular, I will examine the disk correlator between orbifold blow-up moduli and matter Yukawa couplings. Blow-up moduli appear as twist fields on the worldsheet which introduce a monodromy
condition for the coordinate field X. Thus I will focus on how the presence of twist field affects
the CFT calculation of disk correlators. Further, I will explain how the results are relevant to
suppressing soft terms to scales parametrically below the gravitino mass. Last, I want to explore the
relevance of our calculation for the case of smooth Calabi-Yaus.
