The Orion League were a group that consisted of members of the Elder Civilizations which was formed after the Travelers had made first contact with one another after their exodus from Center One. However, the varied differences led to suspicion and unease amongst the seven Traveler tribes which strained their relations. Eventually, this led to the formation of two camps one of which was the Orion League that was led by the scientifically minded Orions whilst their polar opposites were the Central Entente who were led by the militaristic Antarans.
