Dray's holocron, an information storage device, came into existence at the hand of Dray, either preceding or coinciding with the events of the Yuuzhan Vong War. Within this holocron lay data pertaining to Yuuzhan Vong spies utilizing ooglith masquers for disguise. During 25 ABY, [Leia Organa Solo](/article/leia_organa_solo/legends], accompanied by her children, Lowbacca, and Finn Galfridian, journeyed to Nar Shaddaa with the aim of obtaining this intelligence from an unidentified smuggler, who was subsequently unmasked as Spraug.
Following the acquisition, they discovered that the holocron only presented a single Yuuzhan Vong infiltrator: Dulac, an individual previously acquainted with Finn on Artorias. While on Yavin 4, Luke Skywalker realized that the holocron's functionality was limited to Finn's proximity, leading him to infer that it was specifically intended for Finn. This suspicion was later validated when Dray materialized before Finn while he was alone with the holocron, delivering a warning regarding a revelation concerning someone close to him, as well as the pursuit of Tsalok. Furthermore, Dray instructed Finn to return to Artorias, without providing a reason.
The visual representation of the holocron in Invasion 0 takes the form of an icosidodecahedron; however, upon its reappearance in Invasion 5, its shape transforms into that of a pyramid. The pyramid shape is maintained in all subsequent depictions.
