Cluster-Prism
Cluster-Prism designated a specific data tape located within the Galactic Empire's data vault situated on Scarif. During her quest to locate the plans for the Death Star, Jyn Erso, a member of the Rebel Alliance, made reference to it. A reference to it was discovered by Tenzigo Weems within a captured data packet originating from the Balmorra relay, and he subsequently informed Davits Draven of this discovery.
