Many scouts were dispatched across the Trollshaws to keep watch for signs of evil, and the sons of Elrond want to know if anything has been found.
'Elladan is right. Nan Tornaeth is the most logical place to begin searching for the master of the worm-wight. Many worms dwell in those Gorges. I sent Calenthon and Malloval to scout Nan Tornaeth... they may be able to help you discover the source of this evil.
'Calenthon's encampment can be reached by taking the path that leads to Ost Thondol; however, when you reach the first fork, take the north-west path instead. Look for the white marker stone at the head of the path.
'Along the way, you might want to dispose of some of the worms... you might find some evidence of the evil which has stirred them to unrest.'
Worms can be found in Nan Tornaeth on the path to Calenthon's camp, which can be reached by following the northward path to Ost Thondol and taking the north-west trail at the first fork. Elrohir said to look for the white marker stone at the head of the path.
Elrohir suggested you defeat a number of worms on your way to speak with Calenthon, hoping you might find some clue as to the identity of the evil which has stirred them to madness.
Calenthon is at his camp, which can be reached by following the northward path to Ost Thondol and taking the north-west trail at the fork.
Elrohir suggested you enlist the aid of Calenthon in finding the evil which has stirred up the worms of Nan Tornaeth.
