To the Yuuzhan Vong, a familiar or mascot was one who was a trusted aide, a close companion, and if need be, tutor. A familiar had additional meanings and duties which were unknown. Familiars and masters were connected to each other until one died.
Vergere was a familiar to Falung and Elan. Vergere's relationship with the two priestesses was a form of mentorship. Onimi was also the familiar of Supreme Overlord Shimrra. While Onimi used the position to control Shimrra, in public, their relationship was physically abusive, and Onimi functioned as a jester rather than an aide.
