A group of Wretched recently raided a supply of unstable mana crystals from one of our arcane sanctums.  If not handled properly, the crystals could explode with enough force to blow a hole into the city walls.$B$BNow, $N, I don't quite care if they blow themselves up while tapping unstable arcane sources, but the whole incident would make my men look bad.$B$BBring me back any remaining stolen crystals you find; they might still be inside their original crates.
