I am working on a self-written campaign that sticks tight to the original campaign setting of Golarion (including offical PFS Adventures).
Since my party are field agents of the Pathfinder Society and I want to introduce the Aspis Consortion to them, I would like to know what the relationship is between these two factions.
I have read the Inner Sea Guide and know that they work against each other since both are looking for artifacts and other stuff. But how far does this rivalry go? Do they kill each other? Are the leaders in contact and resolve conflicts with diplomacy?
