During the Yuuzhan Vong War, a Yuuzhan Vong battle fleet attacked the planet. The natives were so assured of their own battle prowess that they proudly engaged the Yuuzhan Vong forces. The Vong quickly overpowered and exterminated the warrior race, using their deadly Fire Breathers to wipe out the species. All were lost except for the warrior, Arbeloa, who despite not having contact with other sentient species, attempted to warn others of the impending invasion. After he transmitted this warning into space, he was taken prisoner. This same battle fleet then attacked Artorias in the Outer Rim Territories.
The planet remained unnamed until the release of the The Essential Guide to Warfare. Jason Fry later confirmed on his blog that Vonak is the Cilare's homeworld.
