Three of the Methusalah Stone crystals were lost to antiquity when Rebecca Horne died. She was the only living person who knew the whereabouts of all the crystals. This crystal was given to Aganesthes of Tiryns by his teacher Methusalah. When Aganesthes gave the Methusalah Stone to Rebecca, he kept his crystal for himself as a keepsake. When he died, the stone was believed lost forever, but Rebecca did not know that it was found by another immortal and kept save.
