Daniel Govar - Dernhelm

Dernhelm was the alias taken by Éowyn when she broke the command of her uncle Théoden. As Dernhelm she befriended Meriadoc Brandybuck who was under the service of Théoden, and failed to recognize her. Together they rode Windfola to the Battle of the Pelennor Fields[1][2]. It was as Dernhelm that she first challenged the Witch-king of Angmar.[3]


The name means "hidden protector" in Old English[4] (see Helm).

Portrayal in adaptations[edit]

2003: The Lord of the Rings: The Return of the King:

In the movie, the name is not used. As one of the riders grasps Merry to put him on the horse as they ride for the battle, Merry smiles, immediately recognizing Éowyn from the rider's voice.
