Alfred / Modwenna / Wyrm
Surakian wrote this untitled fanfiction for The Last Kingdom, in which King Alfred gets very sick (when hiding in the Athelney marshes) and Modwenna cures him. She finds out that he has a wyrm in his spinal cord, and her herbal medicine does not seem to work, but when he is as good as dead, she summons the wyrm (that is called Gifer) to go away.
