Walburga of Liege
Walburga of Liege is the persona created by Magdalen of Haphazard Manor specifically for the Golden Swan Tournament.
Walburga is a Beguine, a woman who has chosen to live her life in dedication to God, but to serve him by working among his people in the town of Huy, part of modern day Belgium. Her current year is 1230, and she is a well respected midwife in the town.
A somewhat out of date website about the competition and Walburga in particular exists here.
