Id have to say my number one place would be zertinan caverns (yes i know its infested with all sorts of creppy crawlies) i just love the scene of being underground with the yellow sand and colourful rock plant things and the sunlight poking through the walls. But rabanstre would not be far behind, i absoulutely love the arabian architecture and as being half arabic my self it gives a feel of conection and patriotism.
