Aboard a passenger train car on the planet Kamil during the First Order-Resistance War, a Killik female was traveling while on a mission. During a mission to obtain livestock for the Resistance, Poe Dameron and Finn came across this Killik and its nest.
The Hyperspace Stories 3, penned by Cecil Castellucci and with illustrations by Andy Duggan, marked the Killik's initial appearance. Although Killiks in the Star Wars Legends timeline were depicted as lacking individual identity, this particular Killik uses a first-person singular pronoun, which could be an oversight or an intentional alteration.
