The Titans, also known as the PSO J318.5-22 aliens, are a ferocious alien race from the planet PSO J318.5-22. Their homeworld is a gas giant. They've been known to take Cloudians from Saturn to use as their slave workforce. ("Clouded Hopes" by Xaq)

They now live on gas giants across the PCG Universe.

These characters are always one of the main enemies in the Clouded Hopes Series, and they even attempted to take over Saturn. (Slate The PCG Novel)

History

Slow decline

Because their planet PSO J318.5-22 has no star to keep it warm, they rely on heat from the core of the planet to survive. However, the planet is slowly cooling, leading to a slow death for their civilization. The layers of the atmosphere that are inhabitable to them are diminishing, forcing them to move further and further down into the planet's atmosphere - a practice that is not sustainable.

As such, they began taking slaves to help them relocate to deep within their planet. These slaves were various types of Cloudians taken from planet Saturn. ("Clouded Hopes")

Colony

Over a thousand years later, they'd built a colony on another world, Kepler 138d. There, they conducted genetic experiments on themselves for unknown reasons. ("Clouded Hopes 2")
