Great veins of valuable ores discovered deep within the heart of Atlantis contributed to its early prominence and wealth. Such ores were so plentiful and mined in such quantity that the metals they yielded weren't reserved just for costly weapons and tools. Buildings were roofed with shingles of shining metals; even the poorest Atlantean citizen had metal tools, household implements, weapons, and jewelry. However, the most remarkable sign of the fabulous prosperity, power and wealth of Atlantis were the gleaming metal walls that ringed the island and its capital city. Walls of iron surrounded the nine cliffed citadels that over looked Atlantis.
