HBO has unveiled a Visual Guide to the new Game of Thrones. Featuring interactive maps—including an excellent look at the coast of Essos and the placement of most (but not all) of the Free Cities, apparently based on GRRM’s own maps—and details on various characters, organization, and history, it’s a great guide to the TV show’s version of the novels. There are little changes, here and there, and it’ll be fun spotting some of the departures from the setting’s history in particular.
