Halbarad of the Dúnedain organizes the recovery of the Rangers charged with defending Sarn Ford in the aftermath of the attack some days earlier.
'You say you have a warning for me, Meneldir? Deliver it, then, and be away. We are still recovering from an attack upon the ford that left us scattered and in disarray, and I cannot spare much time for those who break their oaths.
'But I might have some use for your companion. ${PLAYER}, I ask you to aid the defenders of Sarn Ford and gather nearby Ranger caches; they were set aside to provide sustenance and supplies in the event they were needed, and in the aftermath of the attack they surely are!'
Rangers charged with the defence of Sarn Ford can use your assistance. Halbarad also requested that you recover a few caches of supplies from nearby, with which the Dúnedain will be able to restock Sarn Ford.
Meneldir is at Sarn Ford, where he is helping his kin recover from the recent attack.
The earth has been kicked up at several locations near Sarn Ford, and Meneldir thinks you should examine some of those piles of dirt. He has a suspicion that the black riders left something behind, as they did at Herne.
Meneldir's hunch proved accurate: the black riders left a token behind, and it likely drew the wights to Sarn Ford in the days following their attack.
Halbarad is overseeing the recovery of the Dúnedain following the black riders' attack on Sarn Ford.
You retrieved a number of Ranger caches and should bring them to Halbarad.
