Keaths are a subspecies of Aetherians but unlike Aetherians the Keaths communicate with Chirping noises or clicking.
Keaths cant fly by themselves without assistance from other flight based creatures. this is because Keaths has very sensitive hairs on the wings to detect slight vibrations in the air.
Keaths are seen as helpers for the Aetherians, they do a multitude of chores around the home, and they play with children too. most keaths are bred artificially mainly for types of forms that they come in like fluffy, hairy, skinny, beefy or muscular.
Aetherians will use Keaths for testing varis types for effects (mainly electrical equipment) because the Keath's fur is very resistant to electric shock.
