Um, wow. A Lands of Ice and Fire map pack, created by one of the best mappers I’ve found – Jon from Fantastic Maps.
Jon’s blog and the Westeros.org site have further info.
Conceptually this is as cool to me as a Tolkien atlas, or years ago when I found a Dragon Riders of Pern atlas for my mother who was a fan of the series. True that you have to be a nerd, but hey. Yup.
“Now this dazzling set of maps, featuring original artwork from illustrator and cartographer Jonathan Roberts, transforms Martin’s epic saga into a world as fully realized as the one around us.”
