Djinn are related to European faeries, being originally creatures of nature. They acted as nature, being neither good nor evil. But the Choice brought about a change in their essential nature. In response to their acceptance of a decision between the forces of good and evil, God gave Djinn one thing that the European Faeries never had: a soul, whose final disposition is dependent upon the choice made by each Djinni. Thus Djinn can be Muslim or diabolical. There are a few who have not made a choice, but have souls nonetheless and must on day choose.
Some powers are more common in Djinn than others. Most Djinn can also change into the shape of an animal ally to their tribe (see below), and even in their more human forms some physical evidence of that animal remains with them, such as a tail, or small horns, or fur on parts of the body. Many may fly if need be, while almost all can create illusions, an ability learned originally being a part of from the desert.
