In the 46th century BC, this world's native population was known as the Kindir. In 4527 BC, the Caeliar city ship Mantilis crash landed on the planet, carrying twelve Caeliar and six Humans from the Starfleet vessel Columbia. It was here that the last surviving Caeliar Sedín would forcibly merge with the three remaining humans, thus creating the first Borg. Arehaz was targeted for assimilation by the nascent Borg Collective, becoming the origin point for the Borg. (ST - Destinynovel: Lost Souls)
