I am starting a Second Darkness campaign, and one or the PCs is picking "scouting for fiends" as his campaign trait. None of us are super familiar with the pathfinder universe, and I was wondering what faction or group would be a good choice for him to be a part of that could have sent him to investigate. He is a Chaotic-good Half-orc ranger beast-master. Any ideas would be greatly appreciated!
The easiest way would be to have him associated with a good-aligned religion, like Iomedae or Sarenrae. Neither of them are fond of Asmodeus or his fiendish minions.
There's a temple of Cayden Caelian in Riddleport, which might fit well with a CG character.
