Erat was a duchy of the Wacite Arends. The only duchess of Erat was and still is Polgara. The area is now part of central/southern Sendaria. Upon her arrival in Camaar, Polgara claimed to be the Duchess of Erat and acted the part. Captain, later General, Brendig informed her that his uncle was the Earl of Erat. He later informed her that she was the duchess and had a large account being held by the King of Sendaria.
