The orichalcum machine was a massive device located amongst the outer ring of Atlantis. It allowed Atlanteans to forge orichalcum beads for powering their machinery. The machine fabricated these beads from samples of molten orichalcum harvested from the city's deposits. Like much of Atlantean technology, it was decorative as it was functional.
