Long ago, a race of beings known as the Golden Tribe, sent out a telepathic message into the depths of space, to the other races, who were still young. "Come, from the planets you were born on, here into space and join us." Three races answered. The Golden Tribe called them the Silver Tribe (a race that would directly study under the precursors), the Bronze Tribe (a race of sentient insects) and the Heroic Tribe (a race of giants). The Heroic Tribe quickly annihilated themselves save for five individuals, who were subdued by the Golden Tribe and enslaved to the other Tribes.
