Epsilon Miranda V was a planet located somewhere in the space of the galaxy's Alpha or Beta Quadrants, the fifth planet in orbit of the Epsilon Miranda star system. Epsilon Miranda V was the homeworld of the Mirandan civilization.
Late in the year 2364, the Epsilon Miranda star unexpectedly went supernova, blasting away the surface of the planet. Federation science had no reason to expect such an event, and the Mirandans, who did not have space travel capability, were wiped out. Two months later, in early 2365, the starship USS Enterprise-D arrived on system to investigate the unusual stellar activity of the supernova remnant—and found that the star was inexplicably building to an unprecedented second supernova burst. Investigation revealed that a species that fed on high energy levels, the Vortek, had created a neutrino dampening fusion extinguisher device and seeded the explosion in order to feed on the release of power.
