Well, it's like that... if you look at it within the context of Heroes 5, Egypt could have fit well into the world, but in the sixth and seventh games, the mages got the Eye of Horus as a symbol and the Cabiri in Egyptian trinkets. I would split the Academy into Indian, Arabic, and Egyptian factions based on the styles used. Naturally, the djinns and Arab sorcerers would be with the Haven faction, the Indian style would be with the Chimera mages, and the Egyptian style would be with the Necropolis, but this would be suitable for some kind of map or RPG game.
