- "And everyone knows the Night Herald is just a myth you tell the larvae to make them regurgitate."
- ―C-3PO translating Killik speech.
Night Herald was the title given to Welk when he became a Joiner of the Killik Gorog nest, becoming the guardian of the nest's Unseen Queen, Lomi Plo. Upon Welk's death at the hands of Luke Skywalker, Alema Rar, herself having become recently Joined, took up the mantle of Night Herald until her defeat at the hands of Leia Organa Solo and the destruction of the Dark Nest.
