The Hollow Investigative Association has limited research on Alpeca - Energized. After briefly studying its behavioral pattern of spewing liquid Ether, the Association classified Alpeca - Energized as a low-threat Ethereal and ended its investigation.
Scholars once showed great interest in observing how Alpeca - Energized spews liquefied Ether and even commissioned surveys for closer observation.
Experienced investigators have been avoiding such tasks for unknown reasons, however.
