Multiple generations of massive stars have lived and died during Cosmic History, invigorating host galaxies with ionizing photons, kinetic energy, fresh material and stellar-size black holes. At present, massive stars in the Small Magellanic Cloud (SMC) serve as templates for low-metallicity objects in the early Universe. However, recent results have highlighted important differences in the evolution, death and feedback of massive stars with poorer metal content that better matches the extremely low metallicity of previous Cosmic epochs. This paper proposes to supersede the SMC standard with a new metallicity ladder built from very metal-poor galaxies, and provides a brief overview of the technological facilities needed to this aim.
