Strictly speaking, the founder of the Shadow Church is not Anna.
The true founder is Bishop Jon.
Rules, status, faith, all are governed by Jon.
Even the connection between "God and followers" is not very close; among thirty-six core followers, one hundred six retinue members, and over a thousand believers, few have seen Anna in person.
Because Anna does not require their faith.
It is merely that Bishop Jon's faith in the Shadow of the Maiden is devout enough to extend onto Lu Li.
Because of Anna, they too are followers of Lu Li; more and more threads entangled around Lu Li attest to this.
The lair of the Shadow Church is located on the Ailen Peninsula, or perhaps one might say the Main Affinity Continent.
Although the Barren Lands are more hospitable to these heretics, the Shadow Church struggles to enjoy this hospitality — because their god has disappeared.
