The two outlooks in faith clashed over the saturation of the church with mages, although dogma and the rivalry between Zhentil Keep and Mulmaster played a part as well. Similar to the clash with Hillsfar, this did much to keep the Moonsea area free from tyranny.
For a time, there was an orthodox temple in Zhentil Keep, known as the Dark Shrine, headed by a High Inquisitor. However, post-Godswar, it was a splinter church openly worshiping Cyric.
After the Time of Troubles, the High Imperceptor was preparing to convert the church to the open worship of Cyric.
