EXINERIS Industries is an energy company in Final Fantasy XV operating from the town of Lestallum in the Cleigne region of Lucis. It provides the outlands of Lucis with energy drawn from the meteorite shards that are said to have fallen to Eos millennia ago. The meteorite shards exude energy and glow blue. Most of the workers for the energy plant are women, among them Holly. EXINERIS operates a ropeway around the Cleigne area. Lestallum is an industrial city built around the energy business.
When Prince Noctis's party first visits Lestallum, Iris Amicitia will show Noctis around the town. They visit the outside of the EXINERIS power plant, and Noctis learns it mostly employs women. The power plant is later taken over by daemons and the townsfolk hire hunters to dispatch them. Noctis joins the fray and together with Gladiolus Amicitia clears the plant of monsters. Holly, whom the party asks to treat mythril for the use for fixing King Regis's boat, is impressed with Noctis's help, and asks him to check out the malfunctioning ropeway system for her.
When Starscourge overwhelms the world, EXINERIS is the only operating power plant left. It keeps Lestallum illuminated, keeping daemons at bay, and thus most people of Eos migrate there.
