No harm was accepted, considered the only sin. While love? Beautiful, holy, worshipped.. in every possible form.
The greatest pain in this world to the believers of this worship was loss. Fear of a loved one being taken from them, fear of them having to leave a loved one behind, but especially fear of suffering at the end and prolonging that pain for both the sufferer and the ones closest to them. As a man driven by love, the priest sought out to find a way to ease this heavy burden his people faced. He delved deep into Alchemical books, shutting himself away more and more as he devised a plan. He did not know if what he would create would be a god or monster but... With his sacrifice, Revermour was created. A being not fully divine nor human, tasked with caring for the peoples souls as they departed.
