‘Now, friends,’ said Haldir, ‘you have entered the Naith of Lórien, or the Gore, as you would say, for it is the land that lies like a spearhead between the arms of Silverlode and Anduin the Great. We allow no strangers to spy out the secrets of the Naith. Few indeed are permitted even to set foot there.
- The Fellowship of the Ring (Book 2), Chapter 6
The Naith is the land between the rivers Celebrant and Anduin, where the heartland of Lórien lies.
