Roheryn

Aragorn's horse, brought to him by the Dúnedain who came to him in Rohan in answer to his unspoken summons. Roheryn, along with the other horses of the Dúnedain, dared to pass through the Paths of the Dead.

Roheryn means horse of the lady, so called because Roheryn was given to Aragorn by Arwen.
