A Standard Galactic Unit of Time, the Rigon is roughly 1/3rd of a Standard Cycle and is equal to two(ish) Nargons, 60(ish) Malton Units, approximately 1,500 Marbecs, or 90,000 Ribecs, give or take a few. The Standard Galactic Units are based (again, roughly) on the New Terran Units that were adopted soon after the expulsion of Amercadia’s Eastern Hemisphere, once the implementation of the Eastern Matrix (see: Only Possible Recourse, Our) had added the extra marbec to the planet’s rotation and increased (almost doubled, in fact) the time it took for the moon to revolve around the planet. Only after Amercadia had gained sufficient control of its planetary climate was the Rigon (then called “a Fortmoonth”) added to the table of units, dividing the planet’s cycle around its sun into three growing seasons of two Nargons each. Why the Rigon became a standard unit on planets whose growing seasons (or lack of them) had little or nothing in common with those of Amercadia is a matter of debate, though most would agree with the well-known saying that a Rigon is “too long for a start, too short for a finish, long enough to get boring.”
