As mentioned above, Djinn have souls and can accept salvation or side with evil. Some Djinn are very devout Muslims, and are said to be rulers of land under a human overlord. Others seek to corrupt Sahir with promises of knowledge, in the hopes that they will become more powerful themselves. In some instances, there is intense rivalry between evil Djinn and demons. All Djinn lose their power in strong Infernal areas or Dominion. They remain in whatever form they have while under the influence of those areas. Djinn entering into areas opposed to their Choice may suffer a body level every turn if they have a magic might less than twice the level of the aura. This applies to Christian and Jewish auras as well.
More strict forms of Islam hold the Djinn in suspicion, due to their magical nature and secrecy. The Almoravids in Morocco and Spain actively kill any Djinn they find. It is said that because of this, there are Djinn who will aid those who seek the overthrow of the Almoravids, be they Christian, Magus, Sahir, or Muslim.
