- We are CHRONOS, the Guardians of Time! Your predecessor broke the space-time continuum -- Gaia is doomed! - Chronos
Chronos, who referred to itself as the Guardians of Time, was an alien being, or possibly multiple beings, that Filby Young encountered on the Moon during his travels through space and time. It instructed Filby to travel back through time to undo a series of paradoxes that had been created by George Einwin on his travels through time. ("The Time Machine: Trapped in Time")
