[Mashar al-Bisu]
Be wary when you go out travelling through the desert in the dark of the night. Somewhere in the dune lies a djinn far more powerful than any other djinns known to man, excluding the dreadful Iblis and a few others. This djinn in question is known, and feared, by many as Mashar al-Bisu.
Cunning, greedy, sadistic and capricious. These are amongst many words describing this foul spirit. It resembles a travelling nobleman of Byzantine origin, who rides on a brown horse and is always followed by an army of servants, constantly playing music and adulating their proud master.
Whenever it come across a traveller, he will act generous towards them, offering them foods and drinks and a way to its camp, where they could stay for the night. But know to never mistake its supposed "generosity" as an act of kindness; it is all a ruse, the equivalent of moths flying into the flame in hopes of a warmth.
If you do accept its offer to go and stay in its camp for a night, you will be driven into a deep slumber only to wake up in a nightmarish realm where you, and others fallen into Mashar al-Bisu's deceit, are forced into games of life and death, much to the entertainment of the djinn and its many demonic audiences, which are countless sets of floating phantasmal eyes. It is also there where you can finally see its true form: a floating mass of flesh with many maws covering every surface of its being
It matters not as to how much you beg, how much you try to bribe it, and how much you kill it, it would never let you all go. Not without finishing whatever twisted games it would bestowed upon you and winning the prize, and it is the prize where the height of Mashar al-Bisu's sadism has reached its peak.
If you manage to be the winner of its games, you will be given a chance to have your deepest desire look to be made a reality, but at a heavy cost. You will get what you wanted but in exchange, calamity will befall upon you. Unfortunately, even if you know the heavy deal behind the prize, there is no way for you to refused such offer from the djinn, for to refuse it is to enquire its wrath.
So if you ever come across Mashar al-Bisu in the desert, flee. Keep fleeing and do not look back.
