=== Alastor Revanus ===
The founder of the cult, Alastor Revanus (b. E7-477 ; d. E7-549), was a human male originally residing in the town of [[Gimrun]], as the local librarian. He reportedly grew dissatisfied with the influence of both [[Heaven, Ltd.|angelic]] and [[Hell, Inc.|demonic]] factions over the Mazes and did not feel as though they provided proper answers. He started writing the ''Book of Asica'' [[History of the Mazes|sometime in the early 500s of Era 7]], reportedly having spent at least five years writing it. During this period, Revanus's mental stability gradually decreased, friends and neighbors commented on him retiring himself from any kind of social activity and growing more and more asocial , his views radicalizing over time. Notably, Revanus became anti-[[youkai]], and misanthropicthese views are reflected in the ''Book''; he believes that their very existence displeases Asica and that they can never serve her. As such, the Followers have never admitted any youkai members.
After completing and publishing the book in 506, Revanus quit his job and abandoned life in Gimrun in favor of various hideouts and temporary spots in the Uncivilized Area. The [[Maze Police]] suspect him to have committed his first kidnapping and murder shortly afterward. His first victim was Clara Mansfeld, a 23-year-old convenience store manager from Ovis City, who Revanus managed to lure outside of her shop and into the town's public toilets, where her disemboweled remains were found, laid in a ritual circle drawn with the victim's blood. Various symbols, alongside the name "ASICA", had also been etched onto the walls and the floor. This grisly act had shocked the town of Ovis City and is said to have prompted the mayor at the time to sign a contract with the [[Maze Police]] and adopt Standard Law.
