A Hatch was the name of each Kari family. Each Hatch included 20 to 30 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.
