'On the way here, I found quite a few Drúedain bodies in the marsh. They must have fallen to Orcs or the treacherous wildlife. Do you see the necklaces they wear?'
He motions at the Drúedain standing before you. You notice they are wearing decorative necklaces of beads, bones, and feathers. Each is slightly different.
'Those necklaces may be distinct enough to identify their fallen comrades. Search the swamp, collect the necklaces, and burn the Drúedain remains before the deranged creatures of the swamp can devour them any further.'
Drúadan corpses can be found in the wilds of Agarnaith.
You should burn Drúadan corpses and bring back their necklaces.
Ghai-buri-Sêk can be found outside the mountain pass in Agarnaith.
You should talk to Ghai-buri-Sêk.
