"Emil Narud" was the name used by a shapeshifter in service to Amon, though had positions of power in the Moebius Foundation and Terran Dominion. He was viewed as a genius on the zerg biology and an expert on protoss/xel'naga technology. He also has great psionic powers. Narud was the devoted servant of Amon, trying to resurrect him for millennia after his master died. He built Skygeirr Station on top of Amon's temple. There, he combined protoss and zerg DNA to create hybrid creatures of immense power that gathered psionic energy. Narud devised a plan to use a xel'naga device that would make Sarah Kerrigan human again while nearby hybrid gathered the power she wielded as the Queen of Blades, giving him enough energy to resurrect Amon.
