Once aboard the Arks in space, Indogene scientists rotated maintenance shifts, periodically waking up from hypersleep to check on the critical systems aboard each Ark. But even in limited shifts, a person would have aged hundreds years over the five-thousand year journey. Hence, ark-brains were developed – a highly advanced artificial intelligence that governed all facets of navigation, life support, and the eventual terraforming of the destination planet. The ark-brain's primary goal was to protect Votan life at all cost. Most ark-brains were destroyed in the Arkfall event of 2030.
