Majilis Al Jinn is perhaps the most beautiful Sim I have yet seen in Second Life. It reminds me of Al -Analus, or Southern Spain for the 700 year period before 1492 -- when gorgeous Islamic designed buildings such as The Alhambra in Granada took central stage.
The Sim and everything on it are for sale, including full rights for all of Caleins creations. . Please contact Calein Flux if you are interested.
And please make sure to visit, since builds this beautiful have a way of quickly disappearing in Second Life.
