Nehume was a Protoss Dark Templar, or Nerazim. Notable for his penetrating and decisive nature, as a Dark Templar, he was one the few who developed a keen disrespect for the Khalai, disenchanted how their patent ignorance and pride had instigated internecine civil wars even when the Zerg were on the threshold of Aiur, enabling the aliens to overrun the Protoss homeworld while the Protoss were still embroiled in strife amongst one another. He also became animated with an incisive fury with how the Protoss leadership had been manipulated by Infested Kerrigan, so easily deceived by one of the Protoss race's most hated despots.
