Traditionally, a belief or philosophy will be declared heresy by the Prelates Council if it either places another entity on par with the Shaper or if it threatens to lead well-meaning believers to unvirtuous conclusions and purposes.
Some heresies are simple things, such as the Heresy of Androgyny, so declared as it is the belief of the church that thinking of the Shaper in such limited terms as male or female warps a mortal’s understanding of their true nature. Other heresies are the product of particular moments in history, such as the Heresy of Dhá Bhás (gaw vawss) which was declared shortly after Krieger began settling in Tirneach to discourage the idea that Krieger go to a separate afterlife from other species. The Shaper’s virtues and teachings are intended to be universal and it was feared that this may have been the thin end of a splintering wedge. It remains the position of the church that Glüch lies fully within the Shaper’s Hall. Some of these declarations have had their historical context fully lost, no living cinnire or even necromancer has been able to discover the meaning of the Heresy of the Stars but it was recorded that the teachings of a cinnire named Toirdealbhach (tchor-luck) should be given precedence in all matters referring to it.
More dangerous than the simply theologically misleading are Heretical Conspiracies, organised movements that seek to undermine the worship of the Shaper and the society built upon it. These are commonly considered to be the product of Gwyllt interference, however the cinnirí know that there are other beguiling voices that mortal minds may fall victim to and that a charismatic mortal can be just as damaging in the right place and time as any supernatural threat. The Prelates Council works to detect, uncover, and destroy these conspiracies but they often prove surprisingly insidious and resilient. If enough can be learned about a conspiracy and its members, the council has access to powerful rituals that can and will be used against them for the good of the Shaper’s Flock.
