Imagine being able to turn any object into gold. You would be able to produce a vast fortune. Now, imagine if this ability was hereditary and this fortune would keep growing with each generation. That would result in a nigh-limitless fortune that could fund a government many times over. I am thinking of creating an ancient family with this ability in my fantasy series. I will be drawing inspiration from King Midas and the City of Gold, El Dorado. However, unlike King Midas this family would have control over this ability and can only use it through intense focus.
