Charissia was a forest monastery moon located in the Bartahn sector within the Inner Rim Territories that very few smugglers knew about. Many creatures were native to Charissia, including a creature that lived in herds. Prior to the mission to the Ring of Kafrene, Cassian Andor left K-2SO on Charissia to babysit three Wookiees named Wyhyatt, D'Koetaa and D'Lylaa whilst he undertook a raid.
