Hopespyre 2.0 (5E)

From publisher blurb:

Their beliefs considered heretical by the Church of the God of the Sun and their presence viewed as a threat to the cruel ruler of their homeland, the Church of the Redemptive Flame fled and founded a new home in remote Hopespyre. The cult now wants nothing more than to live a sin-free life in their new refuge but events conspire against them. The evil elemental lord of fire has set his sights on the cult and schemes to subvert its good intentions. Aging church leader Dagor Thursh edges closer to death with each day, and a struggle is growing for the right to succeed him, its flames fanned by followers of the elemental lord who have infiltrated the village.
