Even Shi Nee, the most knowledgeable Metal Dragon Master, can't quite figure out why rare metal dragons are so drawn to sleeping on piles of treasure. Not unexpectedly, the larger the treasure pile, the more rare metal dragons will flock to it. How these treasure piles get so large is not as much of a mystery; rare metal dragons are rumored to be magpie-like in their tendency to bring stray valuables back to their dens.
