The Dragon Heart was an orb of solid orichalcum, shaped like a real four-chambered heart. It was a magical tool of such awesome power that Ryan couldn't even comprehend its true purpose. Dunkelzahn had left Ryan with instructions to take it to the metaplanes, to the site where the magic level had spiked artificially high after the Great Ghost Dance. He was supposed to give the Dragon Heart to the woman who protected the site, to Thayla.
