Resurrection is an advanced computer technology that has been developed repeatedly in the Cycle of Time. It was a technology long known to the Messengers, and was developed in different ways, the underlying purpose is to prolong a sentient being's conscious mind.
History[]
The earliest example of Resurrection technology was developed on Kobol by the Twelve Tribes, and was used by the Thirteenth Tribe - a race of sentient biologically-synthetic beings - as a means of prolonging the life of an individual. This technology was abandoned at some point after the Exodus of the Thirteenth Tribe, and subsequent generations on their Earth colony were born through procreation. This technology was redeveloped by the Final Five, a team of Earth researchers, in order to escape a nuclear holocaust. While it is unknown how the technology was used on Kobol, the Final Five were able to digitally duplicate their conscious minds with the technology, which would upload them into cloned bodies once they were determined to have died.
Some two thousand years later, Resurrection technology was developed once more by the descendants of the Twelve Tribes in the form of Caprican computer genius Zoe Graystone, who dubbed it the "Avatar Program". Graystone was in contact with a Messenger for much of her life and was steered towards designing this technology as a counterpart to her father's independent research on artificially-sentient battle robots dubbed "Cylons". She was successful in creating a copy of herself, Zoe-A, who she urged to develop as her own person separate from herself. Following Graystone's death in a terrorist attack in 1942, the Avatar Program was used to create Tamara-A, based on a digital mining of information on Tamara Adams, who died in the same attack. The Avatar Program was later used by the terrorist group, Soldiers of The One, who created a number of other Avatars, but these were killed when their server was destroyed. Zoe-A herself was stranded in various computer terminals until she was placed within a robot body sometime between 1942 and 1947.
Resurrection technology was developed a final time when the Final Five made contact with the Cylon race around 1960, who were fighting a brutal war for mutual survival against the humans. This technology differed once more due to the Cylons' own needs. As part of their agreement to end the conflict, eight biologically-synthetic Humanoid Cylons, "models", were produced. With the Cylons not caring for reproduction or greater numbers, they instead developed millions of clones of these eight prototypes, with millions of copies of the prototype digital consciousness uploaded into each. Further, a cloud server system was developed in which the memories of all individuals of one model could be updated, meaning that any deceased Cylon would undergo Resurrection and gain new memories while sharing their own.
