Operation Cracked Crystal was an operation that was implemented by the Restimar Mining Corporation during the Clone Wars, to covertly mine crystals on the moon Tilnes, in breech of a trade agreement between Restimar and the Verga Mer Mining Company. During the operation, the Corporation sent a team of researchers into the tunnels beneath Tilnes. However, the team's protocol droid guide C4K0 became damaged as a result of an electromagnetic pulse and began to attack the researchers.
