Antipon was the fifth planet in the Zarban system and the neighbor of Zarban itself. It was the first colony world of the Simyastos; a minority of Simyasto historians dated the birth of the Zarban Hegemony from the colonization of Antipon in 203 BBY rather than from the later acquisition of alien-inhabited Fornassan in 14 ABY. While most historians rejected this position, Antipon was under the control of the government on Zarban from its founding.
