"Prince of Persia" tells the tale of Raez's magic carpet ride throughout a parallel, unheard of, dimension. The journey he underwent took him to a place where the most popular activity among Jinns is listening to Purple Rain while playing 3rd generation video-games. Where, inside the many street Bazaars, sacred gems are bought and sold, all hours of the day (and of the 1001 nights) . And where everything is paid for in the local official currency: funky beats.
He could've stayed and become Maharaja (he was actually asked so). But he had to come back to tell the story and, mostly, to share the tunes he come up with.
