Qridus Garcia's provocation
Walchelium Elys was a former member of the church of light. He wasn't a normal member either.
About a thousand years ago, as a cardinal who was in the Supreme realm, he contested for the vacant position of Supreme Pontiff when it became vacant.
However, the Archbishops and Bishops from all the branches voted in the favor of the other candidate as they felt that Elys was a bit too aggressive in his actions, especially against dark organizations where the leader of the Church of light should be benevolent to every human on the planet including the enemies, atleast on the outside.
Once his rival became the Supreme Pontiff, a chain of events happened one after another during the next couple of decades, leading to his resignation from the cardinal's position altogether.
From then on, he was living quietly in the countryside and it's been several centuries since he became a citizen of Southern Qudour.
