Briagh's Lair getting unmarked

[hatsuma]

I ran into several orc patrols during my trek from the Gates of Morning to Briagh's lair, and I kept losing track of it on my map. I finally realized that if you use the rod of recall to return to the fortress, Briagh's Lair disappears off of the map and you have to ask for the location again. Once I stopped recalling and started exiting the ambushes the old-fashioned way I was able to get to it.
