OK, here's the deal. religion can be complicated. And religion in Zakhara is no exception. However if you get a few concepts under your belt, things are a lot simpler. Click on the links to find out a little more.
Firstly Fate is very important. This is why it is called "The Land of Fate"! Fate is a force that affects everyone's lives.
The Gods in Zakhara are a little different to other D&D gods. They are not good, nor evil, not even neutral. They are above such ideas.
A very important person is the Loregiver - who was the first servant of Fate. She defined the Laws of Zakhara under Fate's guidance. This is why they are called "The Laws of the Loregiver".
The person who discovered the scrolls with the Laws of the Loregiver became the first Grand Caliph. The Grand Caliph is a sort of religious leader and also the sort of ruler over all Zakhara, as it is not made up of separate countries.
