Religions of Aelsif: Marakiziyy Monotheism

Below are the details on the predominately human religion of Marakiziyy Monotheism, and its four major sects. Feedback, especially on areas of ambiguity or a lack of detail, would be appreciated. Being the religion in the setting practised over the widest land area, the one practised by the second largest number of people, and the religion of the human homelands and by far and away the most prevalent religion amongst humans by any metric, it seemed a good place to start.

Fair warning: Aelsif is dark and full of terrors.
