Its earliest known ancestor is King Rion Gryphonheart, a Knight who served the Empire of Bracaduun and later founded the Erathian kingdom. The Gryphonheart lineage is also traceable back to Tarnum, whose sister, wholly unbeknownst to the common folk of Antagarich, was Rion's wife. The Gryphonhearts most commonly had red hair, a trait inherited from their maternal ancestor.
