Nimil is a rare metal used in by Nonmen in their weapons and armor, also known as "Nonman steel". It is forged in the sorcerous furnaces of Ishterebinth. In ancient times, nimil was mined in the lowest depths of Cil-Aujas, where the Nonmen used up the lives of several thousand slaves in their efforts to find the metal.
Weapons of nimil are sharper and stronger than any steel blades forged by Men.
