The pre-industrial humanoid inhabitants of Veridian IV, some 230 million people who would all have died had Tolian Soran succeeded in collapsing the Veridian star in Star Trek Generations.
The natives of Veridian IV are a humanoid society at a pre-industrial level of development, living on the fourth planet of the Veridian system. They are unaware of the Federation and are never seen on screen.
They are mentioned in Star Trek Generations. When Data and Picard work out in stellar cartography that Soran intends to destroy the Veridian star so as to pull the Nexus ribbon across Veridian III, Data reports that the shock wave would wipe out every planet in the system, and that Veridian IV has a population of about 230 million.
In the first course of events Soran's probe is launched and the star collapses. Picard leaves the Nexus with James Kirk and returns to a moment before the launch, and the two stop Soran, which saves Veridian IV at the cost of Kirk's life.
