Tham Nambarth is the nearest of those estates and our first priority. While the threats to it are not great they must not be trivalized in their importance, for Tham Nambarth is being reclaimed by nature herself.
Tham Nambarth was once a great hall. You can see that in what still stands today. This will not be the case for long though, and not because of looters, or goblins, or anything else like that. It is the ivy! It grows deep into the cracks in the walls and slowly pushes the bricks apart until nothing is left standing.
It is also threatened now by a source that itself is not threatening. A herd of elk have settled within it's walls. They are not a problem alone, however soon they will bring predators. Wolves, hungry robbers, wargs and goblins from the northern hills.
Tham Nambarth is the most well kept of the estates that lie in ruin within the Twilight Fields.
Tham Nambarth is in the Twilight Fields east of Tinnudir.
