Mol Ni'mai was a male Bothan master armorsmith who designed the Reinforced Insulated Sheath armor. He lived in a hut in the northern mountains of the planet Dantooine during the Galactic Civil War, sometime after the Battle of Yavin. He was visited by a spacer and fellow armorsmith during this time who wished to learn the secret of crafting the R.I.S. armor. After a payment of 50,000 credits, Ni'mai instructed the spacer on the basics of the armor's construction. Once Ni'mai was satisfied that the spacer had learned the essentials and had seen the spacer's armorsmithing prowess first hand, he gave the spacer schematics for each piece of the R.I.S. armor.
