Child of the ProphecyEdit
Muirrin befriends Fainne, her cousin who has come to stay at Sevenwaters. She acts as a healer, creating medicines and herbs for the villagers with ailments. When Maeve is injured in a fire, Muirrin looks after her until Liadan comes to help.
Heir to Sevenwaters
Although she is married and lives on Inis Eala with Evan, Muirrin come into Sevenwaters to assist in the birth of Finbar. After the birth, because Aisling's health is still precarious Muirrin stays to tend to her. She is there when Finbar is replaced by a changeling, and like the rest of the household she sees the changeling as a manikin and not a living thing. Though she listens, she does not believe Clodagh's claims.
Seer of SevenwatersEdit
In Seer of Sevenwaters, she becomes pregnant after six years of trying.
Muirrin is small and slender, with huge green eyes and dark curls for hair.
