Order of Suleiman
Throughout the years since the founding of the Order of Hermes, magi have spoken of the danger that Arabian wizards present, calling them "The Order of Suleiman" and whispering how they seek to bring about the ruin of Hermetic magi. Some speculate that these stories were started by followers of Flambeau the Founder, or perhaps by others opposed to the introduction of similar wizards in Iberia and elsewhere in Europe into House Ex Miscellanea. In any case, the idea that an organized group of Middle Eastern sorcerers exists and plots against them is very common among magi.
They are right.
Of course, this "Order of Suleiman" is not exactly what magi fear it is, though it does pose a grave threat to those who they consider their enemies. It is composed of sahirs, usually unGifted Muslim summoners who wield magic spells and devices similar to their Hermetic counterparts, and who command jinn or other spirits in battle. Their animosity toward the Order of Hermes is fairly recent, as for most of their existence they have been an introverted group, generally devoted to the growth of Islamic culture. Since the start of the Crusades, however, these powerful sorcerers have become more dangerous, and have turned their eyes upon Europe.
Sahirs are designed primarily as adversaries for magi exploring the Mythic Middle East, though it is also possible to play them as player characters in a saga with a Middle Eastern focus.
