She came from Watch Hill to see Mavra Mallen one day before Mavra had to go back to Deven Ride. Afterwards, she stayed to tend the sick and see to the dying sheep, so the Emond's Fielders elected her as their new Wisdom.
She once beat up Alsbet Luhhan with a stick, but no one ever does anything against her, because they are afraid of her fierceness. She lets children fall ill to have a reason to stay a while longer.
