Should send some empty charms..... could be useful..... in case of a "breaktrough" Let's see.... coal, gold and... well, guess I have all materials.... but maybe this disguise-spell should be trained a bit. Just in case you want to move with them... also only on request.. no money needed... I ever wanted to study Djinn I also want to study kitsunes but.... they eat flesh so.... I will prefer you before them!
Actually, there are many types of Djinn, some of which really are monstrous cretins; the Ghul, for example, is a Djinni that rises up out of the ground and devours the flesh of the dead.
These two appear to be Ifrit. Ifrit are semi-insubstantial Djinn made of a sort of living fire. They are exceptionally strong and cunning and are effectively immune to physical harm, but they are easily trapped or killed with magic. Because of their weakness to magic and overall strength, they are common targets for Djinni binding, but this can backfire on the binder when they try to make the Ifrit grant their wish, only for the Ifrit to use its cunning to twist it into something much worse.
Also, while I'm here, I'll also state that Djinn and Genies are not exactly the same creature. Genies were originally European teacher spirits who would accompany a single individual upon their birth to teach and protect them throughout their life. The confusion started when someone translated "One Thousand and One Nights" into English and used the word "Genie" in place of "Djinni" because of their similar pronunciation and the fact that some Djinn occasionally do protect newborns and children.
And sorry about the rant. I'm really into mythology.
