I present a new scenario for the generation of dark and baryonic matter ("hylo" = matter). During low temperature reheating, out-of-equilibrium decays sequester antibaryon number in a GeV-scale hidden sector, thereby leaving a baryon excess in the visible sector. The hidden antibaryons are the dark matter. This model has a unique signature, "induced nucleon decay," where dark matter inelastic scattering can annihilate nucleons at rates relevant for existing nucleon decay searches.
