She is a bellicose, stocky, middle-aged lady with a viking helmet armed with a rolling pin. Her real role in relation to Daphne was never expressly stated. She might be the wife of King Ethelred although she doesn't seem like a queen. It's possible that she may actually be just Daphne's caretaker or nanny.
At first she is angry with Dirk because Daphne was kidnapped by Mordroc and chases Dirk back in Singe's castle. Dirk has to escape her by traveling through time after Mordroc. She is left angry and clobbers a serpent, telling him to shut up.
She appears again at the end of the game, overjoyed to see Daphne having been saved.
