Deep below the ice in Polar City, everyone is asleep. On the surface of Kenopsia, the Custodians are busy making a world. Over the next four million years, they will create a paradise for the sleepers. Custodian 98 wakes and starts its job, working alongside its friend Drone to create clouds, tend the ecosystem, and measure the rain. Over the hundreds of thousands of years, 98 and the rest of the Custodians gently prepare Kenopsia for the wakening—until the day a new star is spotted in the sky and everything changes.
