The Compendium Vita was one of several side projects undertaken by terraforming drones on Clara after their partial terraforming of the planet was complete. It involved a comprehensive cataloging of all life on Clara. Now containing over 500,000 species, it is a treasure trove of information regarding alien life.
Our orders were to terraform a target continent, and then wait for humanity to arrive. They have not contacted us for the past five thousand years. We set out on side projects, projects that may benefit humanity as a whole.
