I argue that the success of the HBO television series Game of Thrones’ portrayal of the character of Lyanna Mormont (as well as fan reception of Arya Stark’s unexpected vanquishing of the dreaded Night King) was due in large part to the writers’ ability to simultaneously capitalize on fan-favorite actions of Éowyn in Tolkien’s source material while avoiding less popular aspects of Peter Jackson and company’s depictions of both Éowyn and the original character Tauriel in their film adaptations.
