East of Ost Guruth there's a small camp atop a hill, where you can find
a vendor and quest-giver named Gwendrada. I just took my level 33
Captain up there ... and she didn't have a ring, nor did her companion.

I assume there's a vector quest somewhere to send you to her. I searched
all through Ost Guruth and found a couple of rings, but none of them had
the vector quest to Gwendrada. Can anyone recall offhand where it is?
If I've got to go to Nan Dhelu and kill dead guys for Radagast, I'd rather
get Gwendrada's two quests also, and make one fell swoop at the place.
