Favored of the Gods (WAR History and Lore)  

Located on the Destruction side of the map inside the RVR lake at approximately 31k/11k. You should see a body hanging from a tree, with a few more corpses strewn at it's roots. One of these corpses belongs to Dagny Betz, examining the body will grant you the unlock.

There is a steep cliff before crossing the line into the RVR area which you will not be able to scale once you drop down, so if you are over-leveled for the area, prepare to be poultry.
