In the world of Evandar, the gods are very active and meddle directly in the affairs of humanity. Some treat them as their servants. Others treat them as their children. And some consider humanity to be nothing more then game pieces to be moved about the board. The gods of the desert and the habitable places within it fall between the position of humanity as their servants and as their children.
The stories of the people of the desert region vary pretty widely about the origins of life. They speak of all things coming into being by way of a goddess, though the exact method of creation is different for each major social group. Some of the oldest tales of the deserts talk of the land once being green and fertile before it was blasted by an angry god. In almost all of the tales of the Waste (the desert upon the continent where Evandar is situated) this angry god is described as the 'black one' or otherwise associated with darkness.
This is another manifestation of the Evandari god of suffering and evil, Morguthu. The primordial goddess is a manifestation of Roen, the Evandari mother of all life. The solar deities are generally male but occasionally genderless, with the capacity to appear of either gender. This latter is a blending of the Evandari gods Sigurt and Kaileth. As one moves through the desert lands, they will find at the very least the trio of cognates to Morguthu, Roen, and Sigurt. There are, however, other minor deities who watch over the people and lands of the desert. Some of those minor deities are quite powerful, such as Ashur the Dacian god of the desert.
The peoples of temperate regions have the base quartet of cognates to Roen, Sigurt, Kaileth, and Morguthu. From region to region, however, there are additional gods who preside over different aspects of life. These additional gods are argued by some to be the children of the first four. Some, however, argue that they are all equally powerful. It is tempting to say that these different deities are of human invention compared to the quartet that are so prevalent through out the world. This, however, is inaccurate.
These other deities (minor or not) do exist and are powerful in their own rights. The deities of the world of Evandar know of each other and interact with each other. Intense rivalries develop between them and equally intense alliances. The gods of Roen, Sigurt, Kaileth, and Morguthu are, however, the eldest of the deities of Evandar. Just as Roen has demigod children by Sigurt and Morguthu, so to do other deities. Their demigod children, however, have a different relationship with humanity then those of Roen's line. The demigods of the different pantheons tend to stay within the geographical region of their believers, though some have traveled beyond those regions.
The only thing that is consistent through all the faiths of the world is that in ages passed, there was a war between the gods and the great god of evil. This war was fought by men and demigods with a great deal of casualties. Entire peoples were lost as a result of that war. Signs of their doomed civilizations lie scattered through out the world. Now, however, signs of that ancient war renewing are appearing through out the world. Evandar is but the center most location of this conflict. And like that ancient war, all pantheons will turn their might against the god of evil in his many guises for the sake of preventing the utter destruction of the world.
