King Aaron Gryphonheart IV was the ruler of Erathia in the early 800s AS. In 817 AS, the people of Harmondale rose up against the Erathian rule. They slew Baron Danforth Octavio, the king's representative, for his exhausting tax collection methods, and made mayor Ty Vespin the King of Harmondale. The new king made Castle Harmondale the seat of his power. Six weeks later, King Aaron marched against him, bringing two legions of veteran soldiers against Harmondale's untrained mobs. King Ty and his loudest supporters were executed, and King Aaron reaffirmed his control of Harmondale.
