> I don't think it's to much to remember what kind of vehicle the characters are traveling in within the same paragraph. I'm reading this and all I can think of is metadata. What kind of books could people write with the right tools? I cannot imagine G. R. R. Martin holding all the knowledge of the universe he designed on his head. I imagine he built a whole on-paper encyclopedia of the world of GoT. I suspect even with all his notes he sometimes makes mistakes and introduces inconsistencies. Are there any world-building tools for writers? (CAW? -- computer-aided-writing... :-p)
