She served as the de facto ruler of Stanlaw since Aethelred spent most of his time in service to with Cyning Cynric II Alfredson. After Edward slew Aethelred at the Battle of Raecford, the official responsibility passed to Aethelflaed.

Few can match her weaving skills. They are so great that rumors abound she is a runelord and weaves her magic into her creations, but that has never been proven either way.
