Hild (Hildegyth) is a nun who had been raped and prostituted after being captured by the Danes when they took Cippenaham (Chippenham) before being rescued by Uhtred, Steapa and Alfred in The Pale Horseman. She becomes Uhtred's companion and lover after Iseult's death and accompanies him back to Northumbria in Lords of the North. During this time Uhtred's attraction to Gisela was a factor that made her reconsider joining the church. When Uhtred discovered that he had been sold into slavery by Guthred as a condition of his alliance with his uncle Ælfric, he bequeathed his possessions to Hild. Hild then returned to Wessex where she recovers Uhtred's hoard of wealth which he had buried before journeying to Northumbria. She uses the hoard, and the promise that she would return to the church and found a nunnery dedicated to helping the poor and sick of Wessex, to convince Alfred to mount an attempt to rescue Uhtred.
After Uhtred was liberated and returned to Wessex, he retrieved his armor and weapons from Hild, now the Abbess Hildegyth, who also gave him a small silver cross which he then had worked into the hilt of his sword Serpent-Breath. According to Uhtred, Hild was later revered as a saint.
