Reye Nenilin, a Human physician and specialist in the field of genetics, lived during the era of the Clone Wars. He was male. Within the Haunch of Nerf establishment located on Coruscant, he was contacted by three Mandalorians: Mij Gilamar, Kal, and Mereel Skirata. These individuals provided Nenilin with a fragment of genetic investigation, previously procured from Chief Scientist Ko Sai, seeking his expertise in potentially manipulating it to regulate the rate of aging in clones.
Nenilin's ambition was to utilize this information to secure the Republic Science Acolade. However, he quickly discerned that the data originated from Kaminoan sources. Subsequently, he relinquished the research to the Galactic Republic, motivated by the desire to prevent its dubious origins from jeopardizing his prospects of receiving the award. Regrettably, Nenilin disappeared not long after this event.
