- The Atuuk are a young species that only recently discovered faster-than-light travel before the Cataclysm stopped their expansion. They are very social and eager to prove themselves within the galactic community. Although small and not the brightest, they compensate with rapid population growth and the ability to focus their entire society on a single goal, called the Great Direction. Their leadership comes in the form of a Great One, a leader chosen to guide them toward their current Great Direction. As goals shift, new leaders with Great Potential emerge to take over.
- The Wekkarus are an ancient, secretive faction with a mysterious past. It is said their ancestors fled an eternal threat. They isolate themselves in fortified Deep Ocean cities and use Defensive Caverns and Deep Labyrinths to protect themselves. Their most unique ability is summoning the “ghosts” of their ancestors for help in times of danger or crisis. These spirits can directly assist them or grant powerful benefits. Their ancient knowledge grants them never-before-seen powerful weapons and components build out their ship with.
