Fearwell is a monotheistic campaign. Paladins are the only class that gets divine powers because the One God believes they need it to protect his “Flock”. Clerics of the one guide are for spiritual guidance only and reject riches and power to better serve him. Paladins are to protect that flock.
There are churches in every city of Fearwell and some shrines throughout the homlets, villages, and even in the wilds.
