Nim was a sergeant in the Dendarii Free Mercenary Fleet. He was in charge of the Dendarii outer perimeter air patrol when Admiral Naismith and Duv Galeni met with Ser Galen and Mark Vorkosigan at the Thames Tidal Barrier. Nim encountered a Cetagandan death squad while monitoring the situation, and was ordered to call the police and avoid entanglement with the authorities. His team successfully withdrew without being arrested.
