[Source] Dray's holocron was created by Dray sometime before or during the Yuuzhan Vong War. The holocron contained information about Yuuzhan Vong infiltrators wearing ooglith masquers. In 25 ABY Leia Organa Solo, her children, Lowbacca, and Finn Galfridian traveled to Nar Shaddaa to acquire this information from an unknown smuggler, later revealed as Spraug.
