from the Introduction:
The creation of this guide is a result of what happened when a I wanted to add a Arabyan sorcerer with a Genie to my campaign and one didn't exist in official or unofficial supplements. Yes, that's all I needed, one single Magi with a Marid Genie, and this is what I ended up with.
While creating this piece I attempted to stay with an Arabian flair to the whole work, while still remaining true to the Warhammer setting. I tried to include what little official information exists on Araby which mainly comes from the Warmaster game. Also of great use was the player made supplement for Warhammer Fantasy Battle: Warhammer Araby. Unfortunately neither of these sources really go into much on the way a Maji is to use a Genie to power their spells, only that they do. So I made it all up the way I liked.
The Maji Career path is very similar to the Wizard Career path while the Djinn themselves are much like a glorified Familiar. As a Maji requires a Genie in order to cast spells a very unique magical atmosphere is added to the setting. One that I think is both fun and interesting to use and play. Though this material was written for my use as a GM it is completely suitable for player use, especially in the southern regions of the Old World.
