Vibration crystal

A vibration crystal was a type of crystal that was used in an arc array. Prior to the Bandit purges, when Captain-Inspector Magna Tolvan arrived to Accresker Jail to meet with Chelli Lona Aphra, Tolvan told Aphra to tell her the components of an arc array to cover up the conversation from an Imperial interrogator nearby.
