What elements of this fictional map do not follow common principles of map hierarchy?

A fictional map is described as the setting or the visual representation of an imaginary or fictional geography. When making a fictional map, one has to consider the real world geography. Take for instance, the real map of London will really make a very good setting and much more if this will be made as an inspiration perhaps in the fantasy map of Ragnarok (role playing online game). The maker of fictional maps may create his / her map based on completeness and complexity that he / she wants to show. This means that the maps made may be made from simple drawings of small areas down to an entire fictional world like in the Game of Thrones by George Martin to even an entire galaxy just like in Star Wars.
