'I have given some thought to our riddle, (your name), and while I do not know if this is the answer, my heart tells me that we must exhaust this course before we can be sure it is fruitless.

'Many caves dot the wilderness of the Trollshaws, home to the creatures that give this place its name. The missing Nazgûl suffered some grievous hurt when caught between the fires of Glorfindel and the Ranger Aragorn and the waters of Bruinen, and he must have escaped to some secluded corner of the wild to regain his strength; I believe he fled to one of the troll-caves.

'I will write down the names and locations of three caves. Descend into the deepest chamber of each and hold Glorfindel's beryl aloft. We must learn if the Nazgûl hid within one of these caves in order to pick up his trail. Bring allies to these caves, for the trolls that lurk within are dangerous. Here are my notes, (your name).'
