A quick teaser…
Shrines of Living Memory
Each shrine or smaller temple dedicated to a particular aspect of one of the Three is named after the cleric or mystic who founded it. This founder’s name is never inscribed in the temple itself, but always transmitted orally. Should the name of the founder of a given shrine or temple be forgotten by living men, the shrine will have lost its sacred nature and must be razed and a new one established in its place.
You have my attention…hmm.
Oh hell. The campaign setting I've wanted for years now.
