The multiloop corrections to the high energy behavior of four-tachyon scattering are studied in string theory. In the limit of high center-of-mass energy, [ital s][r arrow][infinity], for fixed transfer momentum squared, [ital t], we obtain the Regge behavior of the first sister'' trajectory in two-loop scattering. The multiloop-generated sisters are found to be independent of propagator twists, which are necessary for exposing tree-level sisters. The presence of these trajectories in higher order loop diagrams may be sufficient for string theory to be consistent nonperturbatively with locality.
