Seth

Seth was Kane's second in command, and the first superior of the future commander of Nod during the First Tiberium War, who takes his name from the biblical Seth, the third son of Adam. Seth provided briefings for lower ranking Nod officers. He was ambitious man, wary of other commanders with such a trait, who irritate him. This becomes evident evident when Seth passes the order to destroy a civilian village, and remarks that there should be only scientists lurking about, while in reality, there's a fully staffed GDI base in the vicinity. Given Nod's intelligence gathering skills, this is intended misinformation. Seth was shot point blank by Kane after he sends the commander's troops to the United States and orders the commander to attack the country, contrary to Kane's wishes, as part of his plan to take control of Nod.

Instead of simply being disposed of in some manner, his corpse was, as a warning to anyone who would dare circumvent Kane's authority. Captain Nick "Havoc" Parker found his preserved body while attempting to kill Elena Petrova and rescue Sydney Moebius.
