Prehistory is an era spanning from before the start of The Exile.
Notable events include wars between Hiigarans and Bentusi, and finding of first two great Hyperspace cores. The era ended with the exile of Hiigaran people to Kharak and beginning of the rule of Taiidan Empire.
First great event was discovery of the First Great Hyperspace Core by Bentusi. With core in hand, Bentusi established Outer Rim Trade Routes and became the major military force of the time. Second great hyperspace core was then discovered by ancient Hiigarans.
Hiigarans abused the power of long jump core, destroying key Taiidani outposts and bombarding Taiidani homeworld, Taiidan. This ultimately sparked the great war between Bentusi and Hiigarans. During the final battle of the war, Bentusi defeated Hiigarans. Galatic Council voted for survivers of Hiigara to be sent into exile. Bentusi gave up their military might and became peaceful traders. Taiidani moved their imperial palace to Hiigara, from where the corrupt imperium would rule until their defeat at the hands of the Kushan in the Homeworld War. Hiigarans left for Kharak in exile, where they would remain until the discovery of Khar-Toba and their subsequent return to Hiigara in The Exodus.
