Tarkis Arri gave you the location of this secluded stretch of wilderness where you may meet in private.
Points of interest
The area is a desolate former battlefield. There's a couple of bronze shields strewn about the location, but that's about it. The real gem is to the north-west, where Tarkis Arri and her inner council want to talk to you. She offers you her fealty and the loyalty of her men as officers of the Court under your authority (Yeomen Wardens in local parlance).
