Epsilon Theta V was the fifth planet in the Epsilon Theta system. It was a arid Class M planet.
History
In May 2159, during the Earth-Romulan War, all seven planets in the Epsilon Theta system were infected by a metagenic virus planted by the Romulans. However, they were provided with an anti-toxin by a trio of Earth Starfleet Daedalus-class medical ships. An attempt by the Romulan Imperial Fleet to stop the medical ships was thwarted by a task force of Starfleet vessels led by the NX-class Enterprise NX-01, which destroyed the Silvak Outpost that the Romulans had established in the system.
