XKCD (A webcomic of romance, sarcasm, math, and language) offers up a map of online communities done in a fantasy or “D&D” style.
Click on the image above or the image below to be taken to the full map. It’s well worth it as there are any number of excellent (if not obtuse) geek references as well as at least one cartography joke for those of us who enjoy that sort of thing.
