The Ascension

The Ascension is an event where all Kalsian races (aside from the Qetarr) were believed to have gotten into space at the same time. What exactly caused the Ascension is unknown. All that is known is that all of them suddenly had the technology to travel to space and colonize it, and it happened at roughly the same time for all races involved. The point where all of the original Kalsian races met shortly after the Ascension is what marked the beginning of the Kalsian calendar, or year 0.
