As Islam spread, so did the tribes of the Djinn. In some instances, other Djinn were found and told of the Choice, whereupon many fled this world or made a decision themselves. Along with the Jinn, Jann, and loyal Marids, the corrupted Djinn tribes too came north, spreading evil and corruption while battling the Faithful. Many Djinn fought in battles, gaining renown or infamy. By the 7 Islamic century (13 Christian), most Djinn are more reclusive, for the further they stray from the sands and mountains of Arabia and the Holy Land, the weaker they become. Even in the presence of a great holy or unholy place, the powers of the Djinn are suppressed, though they are not destroyed, as they once were. There are even many Djinn who have not made their Choice, though, being bound by the angel's words, they indeed have souls.
Djinn are still concentrated in the Arabian Peninsula and the Holy Land, though some of the more powerful can be found throughout the reach of Islam. Yet every year, as the might of the Christians and the followers of the Prophet grows, fewer Djinn can be found, and it is said that many have given up nearly all their power in order to remain in areas now strong in Dominion.
