The world knows only Four Churches, each great superstructure responsible for worshiping and furthering the causes of One God.
Each Church has its own structure, more details of which will come up in time. The will of the Gods is made known via their Angels, each Angel in physical form is terrifying and powerful, normally they simply possess the bodies of their Dedicated near Portals instead. This process is referred to as "Inspiration" and the Inspired are often canonized as having been touched by the Divine Wind.
Although the Churches do not always agree, they are not at war. They accept the existence of the other Gods and some Priests, in fact, aim to further the causes of all Gods. As Gods only impart power upon their Dedicated, this does not seem to gain the Priests any extra favour from the Beyond.
Each God has 6 Angels and 6 scriptures. Each Dedicated is Dedicated to three scriptures.
Gordian- God of Truth and Knowledge. The Purging Light. Enlightenment.
Virgil. God of Power and Structure. The Hiding Dark. Perfection
Aurelia. God of Love and Emotions. The Mercenary Free. Bliss.
Skepta. God of Community and Loyalty. The Wholesome City. Completion.
Each God is associated with a set of Rituals, and Dedicating yourself to a God grants you some knowledge of these. Each God also has some of their own Rituals, some only available to those Dedicated, or those in their favour, and some available to all.
