The Opal Murders were committed by Crookshank and his helper, the mage Vrinday Kayu in 246 HE. Crookshank had several people digging in his houses for fire opals. As he didn't want others to learn of his opals, he had the diggers killed afterwards. There were three groups of diggers. The first with nine people and the second with eight. All of them were killed afterwards; the first group stabed with swords, the second killed with poison. The Provost's Guard, among them Rebakah Cooper came just in time to save the third crew of diggers from death, among them Jack Ashmiller.
