Astrium

The Astrium is a circular object created by the ancient civilization known as the Zeffo. The Astrium is buried in a Zeffo tomb in Dathomir, known as the Tomb of Miktrull. It is the key to opening the Zeffo Vault on Bogano. In the Vault, Eno Cordova, a Jedi Master who studied the Zeffo civilization, hid a Holocron containing a list of force-sensitive children in order to restore the Jedi Order after the Purge.
