Catalyst Comets

The Catalyst Comet is a massive comet that appears capable of recreating itself, as it hits the Earth every 1000 years. As revealed in "Evergreen" and "Astral Plane", the comet has hit the planet repeatedly, always bringing with it some agent of change. During the time of Urgence Evergreen, the comet appeared green, and it was known that on this occasion its impact would kill even the elemental Wizards. Evergreen sought to prevent this catastrophe using a magical crown he had created to grant its wearer's deepest wish, but was opposed by his fellow wizards. Evergreen responded by freezing the others and proceeding with his plan, but apparently met with failure due to his apprentice Gunter donning the crown. A thousand years later, what appeared to be another Catalyst Comet came hurtling towards Earth, but was noted by Grob Gob Glob Grod as being off in its timing as well as on a trajectory towards Mars rather than Earth. It was diverted back to it's proper course by the sacrifice of Grob Gob Glob Grod, and was revealed to in fact be a spaceship piloted by Martin.
