I got a quest from someone at the Radiant Heart compound to investigate the Fallen Paladins in the Bridge district. They are supposedly led by someone named Anarg (or something similar). I have been through the Bridge district several times and have not run into them. When I talk to people there is no dialog option to ask about them. Am I missing something?
just make sure when you do find them (and it's the house immediately to the right of the Bridge District entrance) you accept their additional quest. From what I remember it gives you some extra XP.
