Caerthynna Alrantora also known as Attiams crown was the mythical founder of the Alran Empire. As the daughter of Camedyr Alrantora she was the inheritor of the jarldom of Ariussealo and the first person born after the end of dwarven rule to hold that title.

Under Attiams Crown the jarldom saw great expansion eastward, due in large parts to her tactical expertise and martial prowess. She claimed the title of monarch of heth after slaying the mythical Grogrisant in the year 68.
