the planet and seek out new homes in space, with the twelve human tribes departing together on the Galleon. The departing humans mythologized their machine counterparts, stylizing them as the "Thirteenth Tribe" of Kobol, and described their journey to a new home, called "Earth". Lacking accurate records, the descendants of the twelve tribes on the colonies assumed that the Thirteenth Tribe was, in fact, entirely made up of humans. Eventually, the Thirteenth Tribe settled on "Earth" and developed sexual reproduction, resulting in resurrection technology falling into disuse and eventual loss. Approximately 2,000 years prior to the events of the re-imagined series, the descendants of the Thirteenth Tribe created their own race of self-aware machines for subservient labor and were, in-turn, killed by their creations in a nuclear war. Five scientists survived due to their work on re-inventing the original Resurrection technology; having been warned in advance by mysterious "angels" that a Kobol-like disaster was coming, the "final five" members of the Thirteenth Tribe downloaded into an orbiting vessel. Hoping to prevent history from repeating itself, they traveled to the Twelve Colonies hoping to avert a war between the humans there and the Cylons, eventually interceding with the Centurions to agree to an Armistice during the first Cylon war. First Cylon War Unaware of the events on Kobol or with the Thirteenth Tribe, the Twelve Colonies developed self-aware, artificial intelligence in the form of the Cylon race, which rebelled and initiated a decade-long war across the colonies. Colonial veterans of this conflict remarked that the Cylons were relentless, highly adaptable, and incredibly resourceful in their ability to wage war. Nearing the end of the conflict, the Cylons began experimenting with their first attempts to evolve with biological components, using captured humans as resources and creating their prototypes for the next generation of basestars and hybrids. The Cylons opted to cease hostilities, declaring an Armistice and promptly disappearing. Second Cylon War After forty years, the Colonial Admiralty sent Battlestar Valkyrie on a covert mission close to the armistice line to gather intelligence on Cylon activity. A stealth ship from the Valkyrie crossed the armistice line, but was intercepted by the Cylons. Three years later the Cylons initiated a surprise attack on the Colonies. The attack was successful because a Cylon agent, later known as Caprica Six, infiltrated Caprica's colonial defense network with the unwitting complicity of renowned scientist Gaius Baltar and created
