A Hatch was the name of each Kari family. Each Hatch included twenty to thirty Kari individuals. An insectoid species, a hive-like society was formed. As such, the Kari possess limited intelligence though one of their unique traits was developing a system of songs that served to teach history from one generation to the next. This resulted in a form of bards being produced among the Kari with each Hatch possessing at least one singer who would preserve the history of the Hatch and "sing" it to other Hatches.
