Lianna was a Silvan elf who lived in the Halls of Thranduil of Mirkwood. She was tasked retrieving a healing draft until she was injured by three Stone-trolls, but she barely managed to escape into Troll Cave. Bilbo Baggins, a Hobbit from the Shire, found her injured and helps her recover from a mortal wound by retrieving her healing draught. Returning to the Woodland Realm, she eventually helps Bilbo escape from Thranduil's Hall. She later takes part in the Battle of the Five Armies. Her fate is unknown after that. She is not featured in Tolkien's original legendarium. Lianna is seen as a blonde, green eyed elf who is ever grateful for Bilbo helping her and later assists him in the Elven Halls rescuing the dwarves.
- Lianna was not in any of the books or movies, she was invented soley for The Hobbit video game and was voiced by Jennifer Hale.
