Many millennia ago, the planet of Dulvoyinn was a planet of many and varied resources. It was originally settled 25,000 years ago by a group of Duros colonists. Three thousand years after the colonization, a pair of stray comets struck the Eastern continent. This collision resulted in years of disastrous seismic activities which shifted the rotation of the planet and razed much of the planetary surface, leaving the much of the landscape barren and useless.
Millions of Duros died during this period. Those that remained faced an everyday struggle to eke out a living from the few resources which remained. The extreme scarcity of resources on Neimoidia was the largest contributing factor to the evolution of the Neimoidians as a race obsessed with gaining material possessions.
The planet of Dulvoyinn I saw its greatest prosperity during the final millennia of the Galactic Republic. The proximity to Coruscant and other galactic trading centers made it an ideal base of operations for the many who wished to stage their dealings away from a watchful eye, but near enough to exert influence.
