Marasai, situated in the Marasa Nebula close to the Trellen Trade Route, was a planetary body. It served as the original home of the Marasans, a cyborg race. Despite existing within the nebula's unpredictable environment, Marasai was known for its mild and balanced ecosystem.
The Marasans' development of agricultural techniques to safeguard their food resources, along with advanced mathematical skills for forecasting weather patterns, stemmed from the volatile climate of their home planet. Their aptitude in mathematics facilitated the creation of hyperdrive technology. Navigation computers implanted within Marasan pilots enabled them to journey from Marasai to the twenty Marasan settlements scattered throughout the nebula. Ultimately, their expertise in navigation played a role in the Galactic Empire's subjugation of the Marasans, resulting in the removal of the Electnodes of the Marasan Mindnet (their governing body) from their positions of authority and forcing their Grand Daern, Derra'makin, into hiding on one of the outlying Marasan colony planets. The Empire achieved this conquest through the utilization of massive resonators capable of interfering with the cyborg implants of all Marasans on the planet, inflicting severe suffering upon them.
