"This relates to the faith system of the Church of Writing." The Goddess of Writing, Reitia, held nothing back and immediately explained her faith system to them, or rather, her divine arts system.
The biggest difference between the Church of Writing and other churches was that rather than calling it a church, it was more like a guild. There were no clear hierarchical divisions internally—everyone was on the same level, unable to manage each other, with no superior-subordinate relationships. Everyone could communicate and learn on equal footing.
In the church system, it was definitely an oddball among oddballs.
Perhaps precisely because of this, the Church of Writing had very few believers, almost negligible. There might not even be more believers than clerics.
But while positions had no hierarchy, divine arts had levels! And advancing in divine arts required not just providing faith, not just gaining recognition from the Goddess of Writing, but more importantly—fame!
