The Dragonslayer Pantheon products by Chubby Monster Games are designed by author Andrew Shields to be incorporated into existing game worlds and provide a new take on one of the religions attached to a god. Each religious order presented includes the common knowledge about the order as well as the secret knowledge of the initiated, non-player characters tied to the order, its practices, suggestions for power levels and adventure hooks using the order and advice for incorporating the group into an existing setting.
Brass Horseshoe is a branch of a warrior cult which knows that wars are not won by courage alone, training, discipline, and logistics win wars far more often. The Order of the Brass Horseshoe seeks to provide and perfect those skills to anyone going to war, seeking perfection in their craft and efficiency in war and in clearing up its aftermath. There is a good question and answer section about how the members of this sect view war and their place in it. The Brass Horseshoe Order is extremely useful allies but it is a pain if they are aiding your enemies.
Overall, I think the Dragonslayer Pantheon product provides a useful set of ideas and options to spark adventure and interest in various religions in a game world.
