The Misery Drive

The United Universe Federation (UUF) fuels their starships with the power of misery and crisis. Whenever a hotspot is found, they first send a small mining contingent of several titans to check if it's a reliable source and not just a statistical anomaly. Once the source is found to be reliable, they typically deploy several leviathans to acquire the entirety of the misery. They have also discovered how to collect and use agonoids radiated by a miseric cloud in the manner of a ramjet; the denser the cloud, the faster they arrive.
