The Pachekki are descended from omnivorous amphibians. Over the aeons they have gradually gravitated towards the land, but they’re still strong swimmers with a great affinity for the water. The race reached its current form about a million years ago. Their present civilization has endured for about 25,000 years. Pachekki evolution has been slow but consistent. They were TL9 space travelers when a Pachekki ship first discovered a colony of another race.
Few other races care to be present at a Pachekki meal, largely because they neither cook nor kill their meat. Modern Pachekki are quite urban, gathering in sprawling cities of several million individuals. The race prefers to build out, rather than up.
Young Pachekki reach majority at age 22 and begin to age at age 55.
Pachekki mate casually and often, though few eggs are fertile. A given Pachekki usually produces about a dozen fertile eggs in its lifetime. The common class is somewhat more fertile than the leaders. Pachekki young traditionally only know their birth parent. Modern Pachekki are trying to increase the number of leaders they collectively produce; leader-type Pachekki will fertilize as many females as possible while in male phase, and (theoretically) will mate only with other leaders while in female phase. The female trait of impulsiveness is hampering this effort, however. Cloning and genetic engineering are also frequently used by the Pachekki.
