Myra is a woman found by the well in Oakvale. She is the woman you need to give the love letter to in the quest The Sick Child. She then asks if you wrote the letter, and if you say you did you get evil points, while if you tell her that it's from Cyril you get good points. If you tell her that the letter came from Cyril, she asks you to take her reply back to him. She goes to Barrow Fields to "tell Fiona all about this" if you made the good choice and she heads off to find Cyril.
