The Vulkron/Primora War
In hopes of increasing their living capacity, Primora attempted to colonize the planet of Vulkron. Primora attacked Vulkron, but was not prepared for their brute strength and harsh climate. The Vulkrons were able to defend themselves quite well, and used the technology of Primorians against Primora. After their initial invasion, lasting about 2 years, they retreated and gave up on their mission to colonize Vulkron, instead they headed to more distant planets for colonization, but were not able to find any suitable environments.
