Mrs. Plithiver is a blind nestmaid snake. She served Soren's family for years before the events of The Capture when Kludd pushed Soren out of their family's nest. Soren found Mrs. Plithiver in the desert of Kuneer while he was hunting. She accompanied The Band to The Great Ga'Hoole Tree by riding on Soren's back while he flew. At the Great Tree she joined the Harp Guild, which is one of the guilds for the nestmaid snakes at The Tree.
