The new faith is nameless(except to those who have joined it). It sprung up sometime in the past 5 years, after the fighting died down. People in fine dark robes with varying colours of stripes/runes on them come to towns, talk to leaders, and are somehow permitted to set up a temple. The largest known temple is in the city of Pentharon.
They call their meetings “The Gathering” and they all tend to be similar. People are welcome to attend, and are handed a cup and a hunk of bread. There is a recounting of the man who became a god’s tale, and then a general sermon telling people not to be wicked, clergy circulates and ask for donations, and possibly what draws people so much to the faith, is that He cares about the people, unlike the other gods, who are cruel. They were never human, they dont know what it was like, and such can never truly understand and care for them.
