Seth

History
Like Kane, little is known about Seth, other than he used to be a high ranking commander in the Brotherhood of Nod. He was responsible for as the mission officer for a young commander during Nod's African campaigns. However, when he attempted to usurp Kane's authority by ordering the commander to attack the Pentagon in the United States, Kane personally executed him. From then on, only Kane would direct Nod's african campaigns.

Personality
Like many in the Brotherhood, Seth subscribed to the theory that power changed quickly in the Brotherhood. Also like many in the Brotherhood's officer corps, he didn't realize exactly how quickly it could change. Seth was also very ambitious, as his attempt to usurp power from Kane shows.
