Ondor has warned you against underestimating the Warg-matron. She has a hungry brood of pups every bit as vicious and hateful as she is.
'The evil matron of this particular Warg-pack has unleashed yet another litter of the filthy beasts upon the world. She may not look like much, but when I was sneaking about earlier, I saw her pups strip the flesh off of an entire ox in a just a few minutes...which gives me an idea.
'That evil spice you made...there is a bit left, yes? A light sprinkle of that into the pups' next meal ought to keep them subdued while you deal with their mother!'
The Warg-matron can be found in the caves of western Nan Curunír.
Ondor suggested a way to defeat the Warg-matron, using the deadly spice to subdue her pups by tainting the horse-meat they feed upon.
Ondor is encamped near the caves of western Nan Curunír.
You should tell Ondor that the Warg-matron has been defeated.
