Page "Planescape" Paragraph 19

David " Zeb " Cook developed Planescape when he was assigned to create " a complete campaign world ( not just a place to visit ), survivable by low-level characters, as compatible with the old Manual of the Planes as possible, filled with a feeling of vastness without overwhelming the referee, distinct from all other TSR campaigns, free of the words " demon " and " devil " and explainable to Marketing in 25 words or less ".

For inspiration, Cook listened to Pere Ubu, Philip Glass and Alexander Nevsky, read The Dictionary of the Khazars, Einstein's Dreams, and The Narrow Road to the Deep North, and for fun at " Bad Movie Nights ", watched such films as The Naked Lunch and Wolf Devil Woman.
