- a tall and thin white-haired woman with ivoried hands who had welcomed the two bereft and bewildered children to the great wooden hall with steely compassion (see In a Stone City).
- it was as if an ancient tree had been felled from under her, or as if the moon had faltered in the sky (see In a Stone City).
From Morwen, Éowyn inherited a wooden casket; shortly after her marriage she took the box with her on a journey to Lossarnach; a local craftsman said that the wood had most likely come from Ithilien (see In a Stone City).
