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.
The Eternal Fall is a beautiful place, toned year-round with the elegance of orange and yellow leaves. In southeastern Zentland, Kava forests sway. Over the mountains of Jonilia, the Turrim Hawk rules the sky. Under the Sea of Alessia, the Rootfish gnaws at corals and sponges. In this category, you can learn about all life in Clara: the large and the small, the predators and the prey, the plants and the animals.
A few decades years before the terraforming drones finished their work, transforming an entire continent, the Earth underwent a cataclysmic nuclear war, followed by an unlucky (god-caused) large asteroid impact. Nearly all human life on Earth was wiped out, and contact between Earth and Clara was cut off.
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.
The drones, therefore, held a council. Some advocated for a termination of the mission. Others argued for loyalty to the cause. Eventually, the loyalists won out. However, there still was the question of what there was to do before the humans came back. The loyalists factions caucused for a few weeks, and devised a detailed roadmap for the next three millennia on Clara.
The loyalist faction leaders suggested that projects be undertaken, for the development of infrastructure and the compiling of knowledge, so that the humans would be better equipped to deal with life on Clara when they arrived. There were ten projects detailed, and one was the Compendium Vita.
