True King/Queen/Sovereign

Throughout history, many people have risen to prominence. People whose names have become synonymous with great deeds and accomplishments. People who lead their fellows through times of crisis and prosperity. Their names are remembered through history.
This is not about these people. The true kings, queens, sovereigns or rulers, or whatever other true title they are known by, are beyond that. These are singular figures of legend, walking myths who shape the world around them by their presence alone. A king, empress or other might rule a nation, but those termed true rulers by people are believed to hold the reigns of the world itself.
Those who earn this title by virtue of their numerous great deeds, be they inspiring or terrifying, are sually referred to by their name, then the epiteth King/Queen/Sóvereign of something, with the something being an element they are heavily associated with. They usually end up as rulers, by virtue of their awesome presence.
This is not a title easily earned. Only the greatest of people have been granted the recognition of this title by the awe they have inspired in people from near and far.
