We study the dynamics of M-theory on isolated non-toric Calabi-Yau threefold singularities of type (A j , A l ) and (A k , D n ), engineering five-dimensional rank-zero SCFTs. Our approach consists in mapping these backgrounds to type IIA string theory with D6 branes at angles and O6 − planes, computing the five-dimensional open string modes located at the brane intersections. This permits us to characterize the Higgs Branches of these theories as algebraic varieties, determine the flavour and gauge group and inspect subtleties related to T-branes. Our methods apply for all the considered singularities: we give a closed formula for the (A j , A l ) Higgs Branches, and tables for the Higgs Branches of the (A k , D n ) series.
